with 22...bxa4? because 23.bxc5 Rxb1 24.Rxb1 dxc5 25.Bxc5 would have left White's central pawns unstoppable. After the game's 22...c4 23.a5! Qe7 24.Bd4 Black's queenside play had ground to a halt; Pintér later won with a pawn advance on the kingside. Variations After the initial moves 1.d4 Nf6 2.c4 c5 3.d5 e6, the moves 4.Nf3 and 4.g3 reach positions discussed previously, while 4.dxe6 fxe6 is also ineffective, since Black gains a half-open f-file and the chance to take over the centre with ...d7-d5. Instead White's most popular move is 4.Nc3, preparing to support the d-pawn with 5.e4. As mentioned above, were Black to delay the capture on d5, White would then gain the option of recapturing with the e-pawn. Thus Black generally plays 4...exd5 immediately. Following the recapture 5.cxd5, Black has an eccentric option in 5...Bd6, the Snake Benoni. But most players prefer 5...d6, which stops White's d-pawn from advancing to d6. Black's control over the central dark squares d4 and e5 will then be augmented by fianchettoing the bishop on g7. Meanwhile, White must decide whether or not to play 6.e4. Although this move gains space in the centre, it also gives Black a target of attack on the half-open e-file. White can deny Black this target for the time being by playing 6.Nf3 first. 4.Nc3 exd5 5.cxd5 d6 6.e4 g6 The most critical lines in the Modern Benoni occur after 6.e4 g6. At this point 7.Nf3 has historically been White's most popular move, intending to complete kingside development and castle. Here theory divides into three major branches: 7...Bg7 8.Be2 0-0 9.0-0, the Classical Main Line; 7...Bg7 8.h3 0-0 9.Bd3, the Modern Main Line; and 7...a6, an attempt by Black to avoid the Modern Main Line. Apart from 7.Nf3, White also has several important alternatives, including: 7.f4, which leads to the Taimanov Attack, Four Pawns Attack, or Mikenas Attack; 7.Bd3, which often leads to the Knaak Variation but may also transpose to the Modern Main Line; 7.h3, which is yet another way for White to reach the Modern Main Line after 7...Bg7 8.Nf3 0-0 9.Bd3; 7.f3, the Kapengut Variation; and 7.Nge2, which was recommended for White in 2012 by Lars Schandorff. The idea is to develop with Ng3, Be2 and 0-0. 7.Nf3 Bg7 8.Be2 0-0 9.0-0: Classical Main Line Before the advent of the Taimanov Attack and the Modern Main Line, the sequence 7.Nf3 Bg7 8.Be2 0-0 9.0-0 was the
