'''M2 митраљез''' или '''Browning .50 калибар митраљез''' је [[тешки митраљез]] дизајниран предкрај [[World War I|Првог свјетског рата]] од стране [[John Browning|Џона Браунинга]]. Дизајн је сличан ранијем Браунинговом [[M1919 Browning machine gun|митраљезу]], који је био дизајниран за [[.30-06 Springfield|.30-06]] калибар. M2 користи много већи и моћнији [[.50 BMG]] (12.7 mm) калибар, који је разивјен упоредо и и своје име носи по самом оружју (BMG значи ''Browning machine gun''). Означен је као "Ma Deuce",<ref>{{cite book |last=Rottman |first=Gordon |title=The US Army in the Vietnam War 1965–73|publisher=Osprey Publishing |location=Reading |year=2008 |isbn=978-1-84603-239-4|page=56}}</ref> у односу на његову M2 номенклатуру. Дизајн је имао много специфичних ознака; званична америчка војна ознака за тренутни пјешадијски тип је '''Browning Machine Gun, Cal. .50, M2, HB, Flexible'''. Ефикасан је против пјешадије, неоклопљених или лако оклопних возила и чамаца, лаких утврђења и нисколетаних авиона. |

The Browning .50 caliber machine gun has been used extensively as a vehicle weapon and for aircraft armament by the United States from the 1930s to the present day. It was heavily used during [[World War II]], the [[Korean War]], the [[Vietnam War]], the [[Falklands War]], the [[Soviet–Afghan War]], the [[Gulf War]], the [[Iraq War]], and the [[War in Afghanistan (2001–present)|War in Afghanistan]] in the 2000s and 2010s. It is the primary heavy machine gun of [[NATO]] countries and has been used by many other countries as well. The M2 has been in use longer than any other [[Small arms|firearm]] in U.S. inventory except the [[.45 ACP]] [[M1911 pistol]], also designed by John Browning. |

Штурмгевер 44 (нем. Sturmgewehr 44) је прва немачка јуришна пушка из периода Другог светског рата, претеча данашњих аутоматских пушака. Студије развоја започеле су 1942. и наставиле се до 1944. Неколико модела је произведено у различито вријеме, као што је МП 43, почетни исход дизајнерских радова на јуришној пушки, Запад и посебно током битке за Нормандију. Извештаји о ефикасности оружја веома су охрабрујући за Немце који одлуче да наставе са побољшањима.[1]
Историја
Током Првог свјетског рата, њемачки инжињер Хуго Шмајсер је закључио да су 7.92mm пушке врло незгодне за јуриш на ровове и зато је развио компактно аутоматско оружје помоћу метака пиштољског калибра који су жртвовали тачност великог домета за мале димензије, малу масу и смањени одбој. Године 1934. Хересвафенамт (војни биро за наоружање) почео је да развија метке средњег домета са скраћеном чауром и смањеном количином барута, и даље способне за ефикасан домет од 400 метара. Године 1938. Амт је издао уговор Ц.Г. Хаенел Вафенфрабрик ће развити машински карабин за настали „7,92x33mm Infanterie Kurz Patrone“ или кратки метак, способан да служи и као аутомат, и као аутоматска пушка, и максимално користи утиснуте металне дијелове како би поједноставила производњу. Главни Хаенелов инжењер Хуго Шмајсер прихватио је изазов постављањем цијеви и кундака у равну линију како би се смањио удар повратног удара, са пиштољским рукохватом за окидач и постављањем нишана. Гасна акција покретала је клип који је покретао затвараћ, а пушка је била сва метална, осим код кундака.
До 1940. године Шмајсер је изнио своје основне ствари, али бројни технички проблеми претходили су његовом прихватању. Погон Хаенел могао је да поднесе мали степен потребне обраде, али није имао алате за штампање, па су они подуговарани са другим компанијама, попут ЕРМА и Мерзверке, које су у том процесу редизајнирале неке дијелове. [2] Од самог почетка, дизајн је требало да обезбеди Њемачкој оружје које би се могло масовно производити, јер су ратни ресурси постајали све оскуднији са сваке године. Користећи Руски фронт као развојни полигон од јула 1943. надаље, пушка се у свом садашњем облику развила у серију МП43 као МП43/1. Овај нови облик омогућио је да се на цијев причврсти бацач граната и садржао је одредбе за постављање оптичких нишана.
Како је рат одмицао, развој МП43 претворио се у систем МП44 који је на крају уступио мјесто новој ознаци Штурмгевер СтГ44 - што је преведено у оно што данас идентификујемо као пушку. Ово је ефективно промијенило идеју ознаке „машински пиштољ“ (по узору на аутомат) у потпуно нову врсту оружја у свијету јуришних пушака. [3] Послије битке за Нормандију, ово оружје користе и њемачке снаге током битке код Ардена. Дизајн јуришне пушке АК-47, који је развио Михаил Калашњиков, у великој мери је инспирисан од стране СТГ 44.[1]
Опис
МП 43, МП 44 и СтГ 44 биле су различите ознаке за у суштини исту пушку са мањим допунама у производњи. Разноликост у номенклатурама резултат је сложене бирократије у нацистичкој Њемачкој.[4] Развијен од Mkb 42(H) "машинског карабина", СтГ 44 је комбиновао карактеристике карабина, аутомата, и аутоматске пуше. СтГ је скраћеница од Sturmgewehr. Према једном извjештају, име је лично одабрао Адолф Хитлер[5][6] из пропагандних разлога и значи „јуришна пушка“ као и „напасти непријатељски положај“, мада неки извори оспоравају да је Хитлер осим потписивања наредбе имао и много везе са ковањем новог имена.[7] Након усвајања СтГ 44, енглески превод „јуришна пушка“ постао је прихваћена ознака за ову врсту пјешадијског малог оружја. Током његове производње дошло је до мањих промена на задњем дијелу, компензатору трзаја, облику основе предњег нишана и степеништу цеви.
Пушка је била направљена за 7.92×33mm Kurz метак.[8][9] Ова краћа верзија њемачке стандардне (7,92×57 мм) пушке, у комбинацији са дизајном селективне ватре оружја, пружила је компромис између контролисане ватрене снаге аутомата из непосредне близине са тачношћу и снагом карабина 98 на средњим дометима. Иако је СтГ 44 имао мањи домет и снагу од моћнијих пешадијских пушака тог дана, армијске студије показале су да се мало борбених дејстава десило на више од 300 m (330 yd) а већина на удаљености од 200 m (220 yd). Пушчани меци пуне снаге били су претјерани за већину употреба просјечног војника. Само обучени специјалиста, попут снајпера, или војници опремљени митраљезима, који су испаљивали више метака на познату или сумњиву мету, могли су у потпуности да искористе опсег и снагу стандардног пушчаног метка.
Британци су били критични према оружју, рекавши да би пријемник могао бити савијен и затварач закључан самим чином куцања наслоњене пушке на тврди под.[10] Америчка процена у касном рату исмијавала је СтГ 44 као „просјечни“, „гломазан“ и „незграпан“, проглашавајући га неспособним за аутоматску ватру и склоном ометању, мада је извјештај прихватио да је његова тачност „одлична за оружје тог типа".[11]

- Берлинска одбрана 3. Сф6
- Морфијева одбрана 3. а6
Морфијева одбрана је најпопуларнији наставак после 2. Лб5. Главни циљ овог потеза је да после , најчешћег, повлачења ловцем на а4, црни добије могућност да путем 4. ...б5, уклони непријатно везивање. Бели сад треба да се чува да не упадне у замку названу "Нојева барка", у којој црни осваја белог ловца са пешачким напредовањем а6, б5 и ц4. Осим 4. Ла5 варијанте, постоји још и варијанта размене са 4. Л:ц6.
- Класична одбрана 3. Лц5
- Норвежанска варијанта 3. Са5
Морфијева одбрана: 3. a6
By far the most commonly played third move for Black is the Morphy Defence, 3...a6, which "puts the question" to the white bishop. The main point of 3...a6 is that after the common retreat 4.Ba4, Black will have the possibility of breaking a future pin on his Шаблон:Chessgloss by playing ...b5. White must take some care not to fall into the Noah's Ark Trap, in which Black traps White's Шаблон:Chessgloss on the b3-square with a ...a6, ...b5, and ...c4 pawn advance on the Шаблон:Chessgloss. Ercole del Rio, in his 1750 treatise Sopra il giuoco degli Scacchi, Osservazioni pratiche dell'anonimo Modenese (On the game of Chess, practical Observations by an anonymous Modenese), was the first author to mention 3...a6.[1] The move became popular after it was played by Paul Morphy, however, and it is named for him. Steinitz did not approve of the move; in 1889, he wrote, "on principle this ought to be disadvantageous as it drives the bishop where it wants to go". Steinitz's opinion did not prevail, however; today, 3...a6 is played in over 65 percent of all games beginning with the Ruy Lopez.[2]
Morphy Defence: alternatives to Closed Defence
After 3...a6, the most commonly played line is the Closed Defence, which goes 4.Ba4 Nf6 5.0-0 Be7, discussed in the two following sections. Alternatives to the Closed Defence described in this section are:
- 4.Bxc6 (Exchange Variation)
- 4.Ba4
- 4...b5 5.Bb3 Na5 (Norwegian Variation)
- 4...b5 5.Bb3 Bc5 (Graz Defence)
- 4...b5 5.Bb3 Bb7 (Caro Variation)
- 4...Bc5 (Classical Defence Deferred)
- 4...Nge7 (Cozio Defence Deferred)
- 4...g6 (Fianchetto Defence Deferred)
- 4...f5 (Schliemann Defence Deferred)
- 4...d6 (Modern Steinitz Defence)
- 4...Nf6 5.Nc3 (Ruy Lopez Four Knights Variation)
- 4...Nf6 5.Qe2 (Wormald Attack)
- 4...Nf6 5.d4 (Mackenzie Variation)
- 4...Nf6 5.d3 (Anderssen Variation)
- 4...Nf6 5.0-0 d6 (Russian Defence)
- 4...Nf6 5.0-0 Bc5 (Møller Defence)
- 4...Nf6 5.0-0 b5 6.Bb3 Bb7 (Arkhangelsk Defence)
- 4...Nf6 5.0-0 b5 6.Bb3 Bc5 (Modern Arkhangelsk Defence)
- 4...Nf6 5.0-0 Nxe4 (Open Defence)
Exchange Variation: 4.Bxc6
In the Exchange Variation, 4.Bxc6, (ECO C68–C69) White damages Black's pawn structure, giving him a ready-made long-term plan of playing d4 ...exd4 Qxd4, followed by exchanging all the pieces and winning the pure pawn ending. Max Euwe gives the pure pawn ending in this position (with all pieces except kings removed) as a win for White.[3] Black gains good compensation, however, in the form of the bishop pair, and the variation is not considered White's most ambitious, though former world champions Emanuel Lasker and Bobby Fischer employed it with success.
After 4.Bxc6, Black almost always responds 4...dxc6. 4...bxc6 is rarely played due to the reply 5.d4 exd4 6.Qxd4 and White is in Шаблон:Chessgloss. After 4...dxc6, the obvious 5.Nxe5Шаблон:Chesspunc is weak, since 5...Qd4Шаблон:Chesspunc 6.Nf3 Qxe4+ 7.Qe2 Qxe2+ 8.Kxe2 leaves White with no compensation for Black's bishop pair.
In the late 19th and early 20th centuries, Lasker had great success with 5.d4 exd4 6.Qxd4 Qxd4 7.Nxd4, most notable his famous win against Jose Raul Capablanca in the St. Petersburg 1914 chess tournament.[4]
Since then, better defences for Black have been developed, and this line is considered to slightly favour Black. Jon Jacobs wrote in the July 2005 Chess Life (p. 21): "A database search (limited to games longer than 20 moves, both players FIDE 2300+) reveals the position after 7.Nxd4 was reached 20 times from 1985–2002. White's results were abysmal: +0−7=13."
After 5.Nc3, Black usually plays 5...f6 to defend his e-pawn. A notable game is Adhiban–Nakamura from the 2013 FIDE World Cup.[5]
The flexible 5.0-0 is sometimes called the Barendregt Variation, but it was Fischer who developed it into a serious weapon in the 1960s. Unlike 5.d4, it forces Black to defend his e-pawn, which he usually does with 5...f6, 5...Bg4, 5...Qd6 (the sharpest line, preparing queenside castling), 5...Qe7, 5...Qf6 or 5...Bd6. A rare but playable move is 5...Be6 (or 5...Be7), the idea being that if White plays 6.Nxe5, Black plays 6... Qd4, forking the knight and the e4-pawn. The move ...Qd4, regaining the pawn at e4, is usually impossible in these variations once White has castled, due to the open e-file.
Notable games are Fischer–Portisch,[6] and Fischer–Gligoric,[7] both played at the 17th Chess Olympiad in Havana 1966.
White may also delay the exchange for a move or two: 4.Ba4 Nf6 5.Bxc6 or 5.0-0 Be7 6.Bxc6 (the Delayed Exchange Deferred), for example; at first glance this seems a waste of time, but Black having played ...Nf6 rules out defending the pawn with ...f6, and the bishop already being on e7 means that ...Bd6 would be a loss of tempo.
Norwegian Defence: 4.Ba4 b5 5.Bb3 Na5
The Norwegian Variation (also called the Taimanov or Wing Variation) (ECO C70), 3...a6 4.Ba4 b5 5.Bb3 Na5 aims to eliminate the white bishop but is generally considered too time-consuming for Black. The usual continuation is 6.0-0 d6 7.d4 Nxb3, but the speculative sacrifice 6.Bxf7+Шаблон:Chesspunc Kxf7 7.Nxe5+, which drives the black king out, has been played. With accurate play, however, Black is supposed to be able to consolidate his extra piece.
In the 1950s, Mark Taimanov played it with some success, though it remained a sideline, as it has to this day. This defence has been known since the 1880s and was reintroduced in 1901 by Carl Schlechter. The Norwegian connection was first introduced by Svein Johannessen who played the line from 1957 and later strengthened when Simen Agdestein and some other Norwegian players adopted the variation. In 1995 Jonathan Tisdall published the article "Ruy Lopez. The Norwegian Variation" in New in Chess Yearbook 37.
Variations combining 3...a6 and ...Bc5
The Graz Defence, Classical Defence Deferred, and Møller Defence combine 3...a6 with the active move ...Bc5. For a century it was believed that it was safer for Black to place the bishop on e7, but it is much more active on c5. White can gain time after playing d4 as the black bishop will have to move, but this does not always seem to be as important as was once thought.[8]
The Møller Defence, 3...a6 4.Ba4 Nf6 5.0-0 Bc5 was already an old line in 1903 when Dane Jørgen Møller (1873–1944) analysed it in Tidsskrift för Schack. Alexander Alekhine played this for Black in the early portion of his career; despite his advocacy, it never achieved great popularity, and even he eventually came to consider it dubious.
The Graz Defence, 3...a6 4.Ba4 b5 5.Bb3 Bc5, was analysed by Alois Fink (b. 1910) in Österreichische Schachzeitung in 1956 and in Wiener Schach Nachrichten in 1979, although it did not become popular until the 1990s.
Modern Steinitz Defence: 4.Ba4 d6
In the Modern Steinitz Defence (also called Neo-Steinitz Defence) (ECO C71–C76), Black interpolates 3...a6 4.Ba4 before playing 4...d6, which was frequently played by Alekhine, José Raúl Capablanca and Paul Keres. The possibility of breaking the pin with a timely ...b5 gives Black more latitude than in the Old Steinitz Defence; in particular, in the Old Steinitz, White can practically force Black to give up his strongpoint at e5, but in the Modern Steinitz, Black is able to maintain his Шаблон:Chessgloss. Most plausible White moves are playable here, including 5.c3, 5.c4, 5.Bxc6, 5.d4, and 5.0-0. The sharp Siesta Variation arises after 5.c3 f5, while a manoeuvring game results from the calmer 5.c3 Bd7 6.d4. The game is also sharp after 5.Bxc6+ bxc6 6.d4 (ECO C73) or 5.0-0 Bg4 6.h3 h5 (ECO C72). The older lines starting with 5.c4 and 5.d4 are not regarded as testing for Black, though the latter offers a tricky gambit. There are six ECO classifications for the Modern Steinitz. White's responses 5.d4, 5.Nc3, and 5.c4 are included in C71, while 5.0-0 is C72. The delayed exchange 5.Bxc6+ bxc6 6.d4 is C73. C74–C76 all begin with 5.c3. C74 covers 5...Nf6, but primarily focuses on 5...f5 6.exf5 Bxf5 with 7.d4 or 7.0-0. C75's main continuation is 5...Bd7 6.d4 Nge7, the Rubinstein Variation. C76 is characterised by the Black Шаблон:Chessgloss fianchetto 5...Bd7 6.d4 g6.
Schliemann Defence Deferred: 4.Ba4 f5
The Schliemann Defence Deferred, 3...a6 4.Ba4 f5, is rarely seen, with practically its only top-level appearance being in the 1974 Candidates Final, when Viktor Korchnoi adopted it versus Anatoly Karpov.[9] It is considered inferior to the regular Schliemann, since White can answer effectively with 5.d4! exd4 6.e5.
Mackenzie Variation: 4.Ba4 Nf6 5.d4
The variation 5.d4 (ECO C77), named after George Henry Mackenzie who employed it on a regular basis, is an old line which, according to modern theory, does not promise White any advantage, though is adopted as an alternative to the main variation 5.0-0. The main line continues with 5...exd4 (5... Nxe4 6.0-0 transposes to the Open Defence) 6.0-0 (6.e5 Ne4 is harmless) Be7 (6...Nxe4 transposes to the Riga Variation of the Open Defence) which leads to the Centre Attack (ECO C84) of the Closed Defence.
Steinitz Defence Deferred: 4.Ba4 Nf6 5.0-0 d6
The Steinitz Defence Deferred (ECO C79) also called Russian Defence. With the move order 3...a6 4.Ba4 Nf6 5.0-0 d6, Black waits until White castles before playing ...d6. This can enable Black to avoid some lines in the Steinitz Defence Deferred in which White castles Шаблон:Chessgloss although the position of the knight on f6 also precludes Black from supporting the centre with ...f7–f6. These nuances seem to have little importance today, as neither the Steinitz Defence Deferred nor the Russian Defence have been popular for many years.
Chigorin played the Russian Defence in the 1890s, and later it was adopted by Rubinstein and Alekhine. The last significant use of the Russian Defence was in the 1950s when it was played by some Russian masters.
Arkhangelsk Defence: 4.Ba4 Nf6 5.0-0 b5 6.Bb3 Bb7
The Arkhangelsk Defence (or Archangel Defence) (ECO C78) was popularized by Soviet players from the city of Arkhangelsk such as GM Vladimir Malaniuk. The variation begins 3...a6 4.Ba4 Nf6 5.0-0 b5 6.Bb3 Bb7. This line often leads to sharp positions in which Black wagers that the fianchettoed bishop's influence on the centre and kingside will offset Black's delay in castling. White has several options, including attempting to build an ideal pawn centre with c3 and d4, defending the e-pawn with Re1 or simply developing. The Arkhangelsk Defence is tactically justified by Black's ability to meet 7.Ng5 with 7...d5 8.exd5 Nd4! (not 8...Nxd5, when White gets the advantage with 9.Qh5 g6 10.Qf3).
Modern Arkhangelsk Defence: 4.Ba4 Nf6 5.0-0 b5 6.Bb3 Bc5
The Modern Arkhangelsk Defence (or Modern Archangel Defence) (ECO C78) is a refinement of the regular Arkhangelsk Defence by incorporating ideas similar to the Møller Defence. Black normally does not fianchetto the Queen's bishop, which would transpose to regular Arkhangelsk setups, but plays ...Bg4 to increase the pressure against White's pawn centre. White's main continuation is 7.a4 after which Black responds with the typical move 7...Rb8 reaching the starting point of this highly complex variation. Another line is the more traditional 7.c3 d6 8.d4 and after 8...Bb6 Black's position is fine. 8...exd4 occurred in Loewenthal–Morphy, London 1859,[10] which seems to be the first time this variation was ever played.
Peter Svidler recorded an entire video series about this defence.[11]
Open Defence: 4.Ba4 Nf6 5.0-0 Nxe4
In the Open Defence, 3...a6 4.Ba4 Nf6 5.0-0 Nxe4, Black tries to make use of the time White will take to regain the pawn to gain a foothold in the centre, with play usually continuing 6.d4 b5 7.Bb3 d5 (but not 7...exd4? 8.Re1 d5 9.Nc3!, Bobby Fischer–Petar Trifunovic, Bled 1961[12]) 8.dxe5 Be6.
Here 8.Nxe5, once adopted by Fischer, is much less often seen, and Black should equalise after the accurate 8...Nxe5 9.dxe5 c6, which avoids prematurely committing the light-squared bishop and solidly defends d5, often a problem in the Open.
The Riga Variation, 6...exd4, is considered inferior; the main line runs 7.Re1 d5 8.Nxd4 Bd6! 9.Nxc6 Bxh2+! 10.Kh1! (10.Kxh2 Qh4+ 11.Kg1 Qxf2+ draws by perpetual check.) Qh4 11.Rxe4+! dxe4 12.Qd8+! Qxd8 13.Nxd8+ Kxd8 14.Kxh2 Be6 (14...f5Шаблон:Chesspunc 15.Bg5Шаблон:ChessAN!) and now the endgame is considered to favour White after 15.Be3 or Nd2 (but not 15.Nc3 c5!, playing to trap the bishop). A famous example of this line is the game José Raúl Capablanca–Edward Lasker, New York 1915.[13] However, this variation has been somewhat revived by a Ukrainian analyst and author Yuriy Krykun in his course on 1.e4 e5 which can be found here https://www.chessable.com/unleash-the-bull-1e5-a-full-repertoire-for-black/course/25866/, as he claimed that while White can keep an objectively better position, Black often obtains some very lively counterplay.
White has a variety of options at move nine, including 9.c3, 9.Be3, 9.Qe2 and 9.Nbd2.
The classical line starts with 9.c3 when Black may choose 9...Be7 (the main line) or the aggressive 9...Bc5.
After 9.c3 Bc5 10.Nbd2 0-0 11.Bc2, Black must meet the attack on e4, with the following possibilities from which to choose: 11...f5, 11...Bf5, both of which aim to maintain the strongpoint on e4, or the forcing line 11...Nxf2, introduced by the English amateur Vernon Dilworth.
Today, 9.Be3 Be7 10.c3 is often used to transpose into the main line, 9.c3, while obviating the option of the Dilworth.
An old continuation is 11...f5, when after 12.Nb3 Ba7 13.Nfd4 Nxd4 14.Nxd4 Bxd4 White can gain some advantage with Bogoljubov's 15.Qxd4. Instead, the very sharp La Grande Variante continues 15.cxd4 f4 16.f3 Ng3 17.hxg3 fxg3 18.Qd3 Bf5 19.Qxf5 Rxf5 20.Bxf5 Qh4 21.Bh3 Qxd4+ 22.Kh1 Qxe5, with unclear consequences. Perhaps the most famous game in this variation is Smyslov–Reshevsky, 1945 USSR–USA Radio Match.[14] An analysis of the line had just been published in a Russian chess magazine, and Smyslov was able to follow it to quickly obtain a winning position. Reshevsky had not seen the analysis and he struggled in vain to solve the position over the board with his chess clock running. The Dilworth Variation (or Attack), 11...Nxf2 12.Rxf2 f6 13.exf6 Bxf2+ 14.Kxf2 Qxf6 has scored well for Black, with many traps for the ill-prepared White player. The main line leads to unbalanced endgames which are difficult to play for both sides, though with a strong drawing tendency. Artur Yusupov is one of the few grandmasters who has adopted the Dilworth repeatedly.[15][16][17]
In the Howell Attack (ECO C81), 9.Qe2, White aims for play against d5 after Rd1. The game usually continues 9...Be7 10.Rd1 followed by 10...Nc5 or 10...0-0. Paul Keres played this line against Max Euwe and Samuel Reshevsky at the World Chess Championship tournament 1948.[18][19]
Karpov's move, 9.Nbd2, limits Black's options. In the 1978 Karpov–Korchnoi World Chess Championship match, following 9.Nbd2 Nc5 10.c3 d4 (10...Be7 is an old move that remains popular) Karpov introduced the surprising 11.Ng5Шаблон:Chesspunc, a move suggested by his trainer, Igor Zaitsev.[20] If Black takes the knight with 11...Qxg5 White regains the material with 12.Qf3. This variation played a decisive role in a later World Championship match, Kasparov–Anand 1995, when Anand was unable to successfully defend as Black.[21]
Closed Defence 4.Ba4 Nf6 5.0-0 Be7: alternatives to Main line
In the main line, White normally retreats his bishop with 4.Ba4, when the usual continuation is 4...Nf6 5.0-0 Be7. Black now threatens to win a pawn with 6...b5 followed by 7...Nxe4, so White must respond. Usually White defends the e-pawn with 6.Re1 which, in turn, threatens Black with the loss of a pawn after 7.Bxc6 and 8.Nxe5. Although it is possible to defend the pawn with 6...d6, Black most commonly averts this threat by driving away the white bishop with 6...b5 7.Bb3.
After 4...Nf6 5.0-0 Be7, the most frequently seen continuation is 6.Re1 b5 7.Bb3 d6 8.c3 0-0, discussed in the next section. Examined in this section are the alternatives to the main line:
- 6.Bxc6 (Delayed Exchange Variation Deferred)
- 6.d4 (Centre Attack)
- 6.Qe2 (Worrall Attack)
- 6.d3 (Modern Line)
- 6.Re1 d6 (Averbakh Variation)
- 6.Re1 b5 7.Bb3
- 7...Bb7 (Trajković Variation)
- 7...0-0 8.c3 d5 (Marshall Attack)
Delayed Exchange Variation Deferred: 6.Bxc6
The Delayed Exchange Variation Deferred (or Exchange Variation Doubly Deferred) (ECO C85), 6.Bxc6, loses a tempo compared to the Exchange Variation, though in compensation, the black knight on f6 and bishop on e7 are awkwardly placed. The knight on f6 prevents Black from supporting the e-pawn with ...f7–f6, and the bishop is somewhat passively posted on e7.
Centre Attack: 6.d4
The Centre Attack (or Centre Variation) (ECO C84), 6.d4, leads to sharp play. After 6... exd4 (6... Nxe4 and 6... b5 are viable alternatives) 7.Re1 b5 (7... 0-0 8. e5 Ne8 is a playable alternative) White can play either 8.Bb3 or the sharp 8.e5. In case of the immediate 7.e5 Black takes advantage of the absence of the white rook from e1 and plays 7... Ne4 with the idea of 8... Nc5.
Worrall Attack: 6.Qe2
In the Worrall Attack (ECO C86), White substitutes 6.Qe2 for 6.Re1. The idea is that the queen will support the e-pawn, leaving the rook free to move to d1 to support the advance of the d-pawn, although there is not always time for this. Play normally continues 6...b5 7.Bb3 followed by 7...0-0 8.c3 and 8...d5 or 8...d6.
Paul Keres played the line several times. More recently, Sergei Tiviakov has played it, as has Nigel Short, who essayed it twice in his 1992 match against Anatoly Karpov and won both games.[22][23]
Модерна линија: 6. д3
Играњем 6. д3[24] White steers clear of the Marshall Attack and any of the Anti-Marshall lines. White threatens 7.Bxc6 winning the e5-pawn leaving Black a choice of either 6...d6 or 6...b5. After 6...d6 the e5-pawn is firmly defended and Black threatens to trade off White's Ruy Lopez bishop with 7...b5 and 8...Na5. White normally continues with 7.c3 and after 8...0-0 White can choose between 9.Nbd2 or 9 Re1. Black can also play 6...b5 and after 7.Bb3 d6 (7...0-0 is a viable alternative) White has to deal with the threat of 8...Na5 by playing 8.a3 (8.c3 or 8 a4 are perfectly playable as well) and after 8...0-0 (the immediate 8...Na5 is also feasible) 9.Nc3 we have reached a modern tabiya of the Ruy Lopez. This position was first reached in a high-level encounter between Viswanathan Anand and Michael Adams, Grenke Chess Classic 2013.[25] 6.d3 has gained wide popularity among the top players and has almost supplanted the Ruy Lopez main line with 6.Re1.
Peter Svidler has dedicated an entire video series to the fashionable 6.d3 line.[26]
Averbakh Variation: 6.Re1 d6
In the Averbakh Variation (C87), named for Yuri Averbakh, Black defends the threatened e-pawn with 6...d6 instead of driving away the white bishop with the more common 6...b5. This defence shares some similarities with the Modern Steinitz and Russian Defences as Black avoids the ...b5 advance that weakens the queenside. White can reply with either 7.Bxc6 bxc6 8.d4 or 7.c3 Bg4 (it is too late for Black to transpose into the more usual lines of the Closed Defence, because 7...b5 would allow 8.Bc2, saving White a tempo over the two-move sequence Bb3–c2 found in other variations). The pin temporarily prevents White from playing d2–d4. In response, White can either force d4 with 8.h3 Bh5 9.Bxc6 bxc6 10.d4, or postpone d4 for the time being and play 8.d3 followed by manoeuvering the queen knight to the kingside with Nbd2–f1–g3.
Trajković Variation: 6.Re1 b5 7.Bb3 Bb7
An alternative to 6...d6 is 6...b5 7.Bb3 Bb7. This is known as the Trajković Variation. Black may sacrifice a pawn with 8.c3 d5 9.exd5 Nxd5 10.Nxe5 Nxe5 11.Rxe5 Nf4.
7...0-0
After 6.Re1 b5 7.Bb3, Black often plays 7...0-0. Here White can play 8.c3, but he has other moves. Alternatives are 8.a4, 8.h3, 8.d4, and 8.d3, which are often called "anti-Marshall" moves. White can also play 8.Nc3 with the idea of playing 9.Nd5 later.
When White opts for 8.c3, Black can and often does play 8...d6, which is a commonly used transposition to the main line. However, he can also play 8...d5 for the Marshall Attack.
Маршалов напад: 7...0-0 8.c3 d5
One of Black's more aggressive alternatives is the Marshall Attack: after 3...a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 0-0 8.c3 Black plays the gambit 8...d5, sacrificing a pawn. The main line begins with 9.exd5 Nxd5 (9...e4?!, the Herman Steiner variation, is considered weaker) 10.Nxe5 Nxe5 11.Rxe5 c6 (Marshall's original moves, 11...Nf6, and 11...Bb7 are considered inferior, but have also yielded good results at top levels of play for Black. GM Joel Benjamin suggests that 11...Bb7 is inferior due to 12.Qf3). The resulting position is shown in the diagram. To the casual observer it might seem that Black has been careless and lost a pawn; however, the sacrifice has also stripped White's Шаблон:Chessgloss of its defenders, given Black a lead in development, and rendered White's 8.c3 irrelevant. Since Black's compensation is based on Шаблон:Chessgloss rather than Шаблон:Chessgloss considerations, it is difficult or perhaps impossible to find a refutation. Black generally goes all-in with a massive kingside attack, which has been analysed to great depth (sometimes beyond move 30) with no definite conclusion as to the Marshall's soundness. The Marshall Attack is a very sharp opening system in which a great amount of theoretical knowledge is vital, and many White players, including Garry Kasparov, avoid it by playing one of the anti-Marshall systems, 8.d4, 8.a4 or 8.h3 instead of 8.c3.[27][није у датом извору]
This gambit became famous when Frank James Marshall used it as a Шаблон:Chessgloss against José Raúl Capablanca in 1918; nevertheless, Capablanca found a way through the complications and won.[28] It is often said that Marshall had kept this gambit a secret for use against Capablanca since his defeat in their 1909 match.[29] The most common counterclaim is that Marshall had used a similar approach in 1917 against Walter Frere.[30] However, Edward Winter found no clear evidence of the date for Frere–Marshall; several games between 1910 and 1918 where Marshall passed up opportunities to use the Marshall Attack against Capablanca; and an 1893 game that used the same line as in Frere–Marshall.[31]
Improvements to Black's play were found (Marshall played 11...Nf6!? originally, but later discovered 11...c6!) and the Marshall Attack was adopted by top players including Boris Spassky, John Nunn and more recently Michael Adams. In the Classical World Chess Championship 2004, challenger Peter Leko used the Marshall to win an important game against World Champion Vladimir Kramnik.[32]
Currently, Armenian Grandmaster Levon Aronian is one of the main advocates for the Marshall Attack.[33]
Main line: 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 d6 8.c3 0-0
The main lines of the Closed Ruy Lopez continue 6.Re1 b5 7.Bb3 d6 8.c3 0-0. White can now play 9.d3 or 9.d4, but by far the most common move is 9.h3 which prepares d4 while preventing the awkward pin ...Bg4. This can be considered the main line of the opening as a whole and thousands of top-level games have reached this position. White aims to play d4 followed by Nbd2–f1–g3, which would firmly support e4 with the bishops on open diagonals and both knights threatening Black's kingside. Black will try to counter this knight manoeuver by expanding on the queenside, taking action in the centre, or putting pressure on e4.
After 6.Re1 b5 7.Bb3 d6 8.c3 0-0, we have:
- 9.d3 (Pilnik Variation)
- 9.d4 (Yates Variation)
- 9.d4 Bg4 (Bogoljubow Variation)
- 9.d4 Bg4 10.a4 (Yates Variation, Short Attack)
- 9.a3 (Suetin Variation)
- 9.Bc2 (Lutikov Variation)
- 9.h3
- 9...Na5 (Chigorin Variation)
- 9...Nb8 (Breyer Variation)
- 9...Bb7 (Zaitsev Variation)
- 9...Nd7 (Karpov Variation)
- 9...Be6 (Kholmov Variation)
- 9...h6 (Smyslov Variation)
- 9...Qd7 (Smyslov Variation)
- 9...a5 (Keres Variation)
Pilnik Variation: 9.d3
The Pilnik Variation, named for Herman Pilnik, is also known as the Teichmann Variation from the game Teichmann–Schlechter, Karlsbad 1911.[34] White plays 9.d3 intending to later advance to d4 under favourable circumstances. Although d2–d3–d4 appears to lose a tempo compared to d2–d4, White may be able to omit h3 regaining the tempo, especially if Black plays ...Bb7.
Yates Variation and Bogoljubow Variation: 9.d4
White usually plays 9.h3 instead of 9.d4 (the Yates Variation) because after 9.d4 Bg4 (the Bogoljubow Variation), the pin of the white Шаблон:Chessgloss is troublesome. The variation takes its name from the game Capablanca–Bogoljubow, London 1922.[35]
Chigorin Variation: 9.h3 Na5
The Chigorin Variation was refined by Mikhail Chigorin around the turn of the 20th century and became the primary Black defence to the Ruy Lopez for more than fifty years. With 9...Na5 Black chases the white bishop from the a2–g8 diagonal and frees the c-pawn for queenside expansion. After 10.Bc2 c5 11.d4 the classical Black follow up is 11...Qc7, reinforcing e5 and placing the queen on the c-file which may later become open after ...cxd4. Other Black moves in this position are 11...Bb7 and 11...Nd7; the latter was adopted by Keres a few times in the 1960s. The Chigorin Variation has declined in popularity because Black must spend some time bringing his offside knight on a5 back into the game.
The Chigorin is divided into four ECO classifications. In C96, Black or White deviate after 10.Bc2, and do not reach the classical main line position 10...c5 11.d4 Qc7. In C97, White proceeds from the diagram with 12.a4, 12.d5, 12.b4, or the main line 12.Nbd2 when Black responds with ...Be6, ...Rd8, ...Re8, ...Bb7 or ...Bd7. The C98 classification covers 12.Nbd2 Nc6, while C99 covers 12.Nbd2 cxd4 13.cxd4.
Breyer Variation: 9.h3 Nb8
The Breyer Variation was recommended by Gyula Breyer as early as 1911,[36] but there are no known game records in which Breyer employed this line. The Breyer Variation did not become popular until the 1960s when it was adopted by Boris Spassky and others. In particular, Spassky's back to back wins over Mikhail Tal at Tbilisi in 1965 did much to enhance its reputation, and Spassky has a career-plus score with the Breyer. The variation is the choice of many top level players today as White has had trouble proving an advantage against it.
With 9...Nb8 Black frees the c-pawn and intends to route the knight to d7 where it supports e5. If White fortifies the centre with 10.d3 the opening is classified ECO code C94. The more common continuation, 10.d4, is ECO C95. The main line continues 10.d4 Nbd7 11.Nbd2 Bb7 12.Bc2 Re8 13.Nf1 Bf8. Black is threatening to win the e4-pawn via ...exd4 uncovering an attack on the pawn, so White plays 14.Ng3. Black generally plays 14...g6 to stop White's knight from going to f5. White then usually tries to attack the Black queenside via 15.a4. Black seeks Шаблон:Chessgloss in the centre via 15...c5. White can attack either the kingside or the queenside. This forces resolution of the centre via 16.d5. Black can exploit the weak squares on the queenside via 16...c4. White will try to attack on the kingside via 17.Bg5, moving his forces to the kingside. Black will kick the bishop with 17...h6. The logical retreat is 18.Be3, which is met by 18...Nc5. White plays 19.Qd2, forcing 19...h5. The point of this manoeuver was to weaken Black's kingside.
Zaitsev Variation: 9.h3 Bb7
The Zaitsev Variation (also called the Flohr–Zaitsev Variation) was advocated by Igor Zaitsev, who was one of Karpov's trainers for many years. A Karpov favourite, the Zaitsev remains one of the most important variations of the Ruy Lopez. With 9...Bb7 Black prepares to put more pressure on e4 after 10.d4 Re8 11.Nbd2 Bf8, when play can become very sharp and tactical. One drawback of this line if Black is playing for a win is that his opponent can force him to choose a different defence or allow a draw by repetition of position with 11.Ng5 Rf8 12.Nf3.
Karpov Variation: 9.h3 Nd7
Karpov tried 9...Nd7 several times in the 1990 World Championship match, but Kasparov achieved a significant advantage against it in the 18th game. It is solid but slightly passive. Confusingly 9...Nd7 is also called the Chigorin Variation so there are two variations of the Ruy Lopez with that name, but 9...Na5 is the move more commonly associated with Chigorin. This defence is also known as the Keres Variation, after Paul Keres.
Колмов варијанта: 9. х3 Лe6
Колмов варијанта, 9. Лe6, је била популарна 1980-их али се данас ријетко игра. Главна линија је 10. д4 Л:б3 11. a:б3 (11. Д:б3 је друга опција) e:д4 12. ц:д4 д5 13. e5 Сe4 14.

Варијанта Смислова: 9. х3 х6
Варијанта Смислова (ECO C93) је план сличан варијанти Зајцев. Са 9. х6 црни се спрема играти 10. Тe8 и 11. Лф8 без страха од 10. Сг5. Губитак темпа са 9. х6 даје бијелом довољно времена да заврши Сбд2–ф1–г3 маневар, и потез пјешака може ослабити краљеву страну црнога. Зајцев се може сматрати побољшаним Смисловом у коме црни покушава да сачува темпо изостављањем х6.
Каспаров је играо варијанту Смислова у губитку против Deep Blue-а шаховског компјутера у 2. игри из 1997. Меч човјек против машине.[37]

The Indian waited for things to unfold rather than forcing the pace in his characteristic way but after waiting for sometime on move 21 he deviated from the known track. Though he seemed to have got something out of the opening, the World champion did not have anything special.”

4chan је анонимни енглески веб-сајт за отпремање и преглед слика. Покренут од стране Кристофера "moot" Пула у октобру 2003, 4chan угошћује табле (board-ove) посвећене најразличитијим темама, од аниме-а и манге до видео игара, музике, литературе, фитнеса, политике, и спорта, између осталог.[2] Регистрација није могућа, и корисници сајта објављују анонимно; приче које примају недавне одговоре "набијају се" на врх своје табле и старе приче се аутоматски бришу како се креирају нове. 4chan прима више од 22 милиона јединствених мјесечних посјетилаца, са приближно 900,000 објава свакодневно.[3][4]
Страница је креирана као пандан јапанској страници Futaba Channel, такође позната као 2chan,[5] и прве табле су направљене за објављивањљ слика и дискусија везане за аниме. 4chan је описан као средиште интернетске субкултуре, при чему је заједница веб локације утицала на формирање и ширење истакнутих интернет мимова, укључујући лолкет, рикролинг и рејџ комиске, као и хакерске покрете попут Анонимоус. Иако је раније постојао велики број лијево оријентисаних либертаријанских активиста 4chan-а, дошло је до постепеног окретања десници на политичкој табли 4chan-а. Ова смјена се догодила средином 2010-их..[6] Значајни 4chan активизми укључујући акције преузете против Сајентолошке цркве као и против политичких покрета попут Окупације, Арапског прољећа и алт деснице.[7][8] 4chan је често био предмет медијске пажње као извор контроверзи, укључујући координацију подвала, узнемиравања, напада на друге веб странице и кориснике Интернета и објављивање илегалних садржаја, претњи насиљем, мизогинија и расизма. The Guardian је једном приликом резимирао заједницу 4chan-a као „луђачку, малољетничку ... бриљантну, смjешну и алармантну“".[9]

M2 митраљез или Browning .50 калибар митраљез је тешки митраљез дизајниран предкрај Првог свјетског рата од стране Џона Браунинга. Дизајн је сличан ранијем Браунинговом митраљезу, који је био дизајниран за .30-06 калибар. M2 користи много већи и моћнији .50 BMG (12.7 mm) калибар, који је разивјен упоредо и и своје име носи по самом оружју (BMG значи Browning machine gun). Означен је као "Ma Deuce",[1] у односу на његову M2 номенклатуру. Дизајн је имао много специфичних ознака; званична америчка војна ознака за тренутни пјешадијски тип је Browning Machine Gun, Cal. .50, M2, HB, Flexible. Ефикасан је против пјешадије, неоклопљених или лако оклопних возила и чамаца, лаких утврђења и нисколетаних авиона.
The Browning .50 caliber machine gun has been used extensively as a vehicle weapon and for aircraft armament by the United States from the 1930s to the present day. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan in the 2000s and 2010s. It is the primary heavy machine gun of NATO countries and has been used by many other countries as well. The M2 has been in use longer than any other firearm in U.S. inventory except the .45 ACP M1911 pistol, also designed by John Browning.
The current M2HB is manufactured in the U.S. by General Dynamics[2] Ohio Ordnance Works,[3] and U.S. Ordnance[4] for use by the U.S. government, and for allies via Foreign Military Sales, as well as by foreign manufacturers such as FN Herstal.
