1.e4 c5 2.c3 d6 3.d4 Nf6 An antidote to the 2 c3 system that is now used frequently. If now 4 dxc5 with the idea 4 ... Nxe4?? 5 Qa4+ or 4 ... dxc5? 5 Qxd8+, then Nc6, intending 5 cxd6 Nxe4, 5 Bd3 dxc5, or the pawn sac 5 f3 d5! 4.Bd3 Nc6 Black can also play 4 ... g6, avoiding the inconvenience of a later d4-d5 hitting the knight on c6. An interesting line is 4 ... g6 5 Nf3 Bg7 6 O-O O-O 7 Re1 Nc6 8 d5 Na5!? 5.Nf3 Bg4 5 ... g6 6 d5 is not so appetizing now for Black. 6.d5 Bxf3 Of course not 6 ... Ne5?

7 Nxe5 Bxd1 8 Bb5+ 7.gxf3 Ne5 8.Be2 Kotliar preserves the 2 bishops and bases his strategy on his space advantage. 8...g6 9.c4 Bg7 10.Nc3 0-0 11.f4 Ned7 12.Qd3 a6

White's original play has given him a good game, and he is about to embark on a kingside attack. But before staking everything on a direct attack, it is imperative to deny Black the chance for Benko-Gambit-style counterplay. Clearly correct is 13 a4! and if then 13 ... Qa5, then 14 Ra3! 13.h4? b5 14.cxb5 axb5 15.Nxb5 Ra4 The position has transformed, and Black has the superior practical chances. 16.Nc3 Rb4 It is hard to find a concrete follow-up to 16 ... Rd4 17 Qc2. 17.a3 Rb3 18.Qc2 Rb7 19.h5 Qa5 20.hxg6 fxg6 The correct recapture, despite the weakening of e6.

Moulin now has the unusual task of combining Benko Gambit play with pressure on the f-file. But Kotliar's pawn center and control of the light squares is not to be underestimated. 21.Kf1 Rfb8 22.Nd1 Moving into a defensive mode. Things could have gotten wild on the sealer-sweeper 22 e5! dxe5 23 f5! 22...Nb6 23.Nc3 Ra7 24.Ra2 Na4 25.Nd1 Nb6 After all that work to get the knight to a4, he should have left it there and played 25 ... Rab7. 26.b3 Nbd7 27.Bc4 Nh5 28.Qe2 Rf8 29.Bd2 Qc7 30.Rh4 Rfa8 31.a4 Qd8

White has built up a fantastic position. Perhaps it was time for a4-a5-a6, but Kotliar decides that the time is ripe for a positional exchange sacrifice. 32.Rxh5 gxh5 33.Qxh5 Kh8 34.f3 Nb6 35.Bd3 Qe8 36.Qh3 Bd4 37.Nf2 c4 Suddenly Moulin becomes very active. 38.bxc4 Rxa4 39.Rc2 Ra1+ 40.Ke2 Na4 41.e5 h5 42.Qe6 Qf7 43.Qh6+ Kg8 44.Ne4 Qg7 The position is unclear after 45 Qxg7+ Kxg7 46 Ng5.
