1.d4 Nf6 2.Nf3 c5 3.d5 b5 4.e4


4...Bb7?! According to my database this move had been played only once. [I'm not sure about White's intentions after the most natural 4...Nxe4 as 5.Bxb5?? would just blunder a bishop after 5...Qa5+, however both 5. Nbd2 and 5. a4 seem to give White strong initiative for the pawn.] 5.Bxb5 So, we got a new position on 5th move! [5.Nbd2 Qa5 6.c3 e6 7.Nb3 Qb6 8.dxe6 dxe6 9.e5 Nfd7 10.Be2 etc., Jahner, M-Rafiee,M (2048)/Willingen 2006/] 5...Qa5+ [5...Nxe4 6.0–0 and it would be really hard to finish the development for Black - 6...e6 7.c4 Be7 8.Nc3!

14.Bxc6?! Inaccuracy, which gives away huge part of White's advantage. [Much stronger would've been 14.Qh5+! Kxd7 (14...g6? loses on a spot after 15.Qe5) 15.Qf7+ Kd8 16.Rd1+ Bd5 (16...Kc8 17.Bxc6 Qxc3+ 18.Kf1 Nxc6 19.Qd7+ Kb8 20.Qxc6+-)


17.Qxe6 with decisive advantage, for instance 17...Qxb5 18.Qxd5+ Kc7 19.Qxa8 Re8+ 20.Kd2 Qe2+ 21.Kc1 Nc6


22.Rd7!+ Kxd7 23.Qb7+ Ke6 24.Qxc6+ Kf7 25.Qxc5+-] 14...Qxc3+ 15.Qd2 [15.Kf1 Nxc6 16.Qd6 Qxc2 17.Rb7 Qc4+ 18.Ke1 Qc3+=] 15...Qxd2+ 16.Kxd2 Nxc6 17.Nxc5 White has won a pawn, however Black's rising initiative promises him some compensation. 17...0–0


18.Nd3?! [18.Ne4!? Rad8+ 19.Ke3 Rd4 20.Rb7 Ra4 21.Rd1±] 18...Rad8 19.f3 Rf5 20.Ke3?! [20.Rb7 Ra5 21.Ra1! with some chances to convert the advantage.] 20...Ra5 21.Rb2 Ne5! Now Black is out of danger. 22.Nxe5 [22.Ke2 Nc4 23.Rb4 Nb6 24.Ra1 Rc8 25.Kd2 Nc4+ and Black's active pieces fully compensate minimal material deficit.] 22...Rxe5+ 23.Kf4 Re2 24.Kg3 h6 [24...Rdd2 25.Rg1 Rxc2 26.Rb8+ Kf7 27.Rb7+ Kf6 28.Rxa7 Rxa2 29.Rxa2 Rxa2=] 25.a4 Rd4


26.c3 White failed to find any chances to win this game and decided to force simplifications. 26...Rxb2 27.cxd4 Ra2 28.Rd1 Rxa4 29.d5 exd5 30.Rxd5 1/2

Muzychuk, Mariya - Can, Emre

1.e4 c5 2.Nf3 d6 3.Bb5+ Bd7 4.Bxd7+ Qxd7 5.c4


This move leads to Marozi-type pawn structure. The position shouldn't be that dangerous for Black, however some precision is required. [Another option for White is 5.0–0 Nf6 6.Qe2 (6.Re1 e6 7.c3 Be7 8.d4 cxd4 9.cxd4 d5 10.e5 Ne4 11.Nbd2 Nxd2 12.Bxd2 considered to be absolutely harmless.) 6...e6 7.c3 Be7 8.d4 cxd4 9.cxd4 d5 10.e5 Ne4 11.Ne1 Nc6 12.Be3 with complicated struggle.] 5...Nf6 [An attempt to snatch the pawn is quite dubious - 5...Qg4 6.0–0 Qxe4 7.d4! and White has strong initiative.] 6.Nc3 g6 [Bad for Black would've been 6...Qg4 7.0–0 Nxe4 8.Qb3! and White is nearly winning.] 7.0–0 Bg7 8.d4 cxd4 9.Nxd4 0–0 10.f3


10...Rc8 11.b3 d5! 12.exd5 [12.e5 Ne8 13.Nxd5 e6 14.Nc3 Bxe5 15.Nde2


15...b5! and has got a nice position in Vescovi,G (2633) -Areshchenko,A (2564)/Moscow 2004/] 12...Nxd5 13.Nxd5 e6 14.Bh6 exd5 15.Bxg7 Kxg7 16.cxd5 Accepting the fact White has got nothing from the opening. (16.c5 Na6 17.Nc2 Nxc5 18.Qd4+ f6 19.Ne3 Ne6 (Kamsky,G (2705)-Gelfand,B (2733)/Elista 2007/) and here White should've take on d5 with equality.)


16...Rxc5?? Terrible blunder! 17.Nf5+ and Black resigned.[17.Nf5+ Qxf5 18.Qd4+ Kg8 19.Qxc5 +-] 1–0

Kaya Emel - Ozturk, Kubra


Black has got serious advantage in the previous stage of the game and here Kubra goes for a nice exchange sacrifice: 23...c5! The easiest way to convert the advantage! [23...Kc5? 24.Nxe5 Bxe5 25.Rxd7 and White can hope to survive.] 24.Bxa8 Rxa8 25.Nxd4 [25.Ng5 f6 26.Ne4+ Kc6–+] 25...exd4 26.Ra1 Rxa4 27.Rxa4 Bxa4


The worst thing for White is the fact that he's losing c4 pawn. 28.Ra1 Bb3 29.Kf1 Bxc4+ 30.Ke1 Bb3 Black pawns are unstoppable. 31.Kd2 h5 32.Rh1 g6 33.f3 Be6 34.Ra1 c4 35.Ra5 c5 36.Ra7 Ke5 37.Rc7 c3+ 38.Kc2 Kd5 39.g4 h4 40.Ra7 h3 41.Ra8 h2 42.Ra1 Kc4 43.Ra4+ Kb5 44.Ra1 Bd5 45.Rh1 Kc4 0–1

Iordachescu, Viorel - Nielsen, Peter Heine


Black had been overplayed and has to give the pawn. 32...Bb6! Best practical chance! 33.Qxc6?! Tempting but not the best. Perhaps White underestimated Black's defensive potential in arising endgame. [Much stronger would've been unexpected 33.Bxf6! gxf6 34.Qxc6 and the opposite colored bishops doesn't promise Black an easy life - 34...Kg7 (34...Qc7? 35.Qxf6+-) 35.Bd7!


35...d4 (35...Qc7 36.Qxc7 Bxc7 37.d4! and White is winning d5-pawn.) 36.Qd5!+- with complete domination and no chance to give the opponent any counterplay.] 33...d4! 34.Bb2 Qd5+ 35.Qxd5 Nxd5


36.Bf5? [36.Ba3! cutting the king, would probably still be enough to win the game. 36...Nc3 37.Bd7! and than White should be able to open up the kingside and activate the king with decisive effect.] 36...Nc3! Setting a sort of fortress on the queenside. 37.Bd7 Bc5! 38.Bc1 Kf8 39.Bf4 Ke7 40.Bc6 Bd6

Just in time! White can't make any progress. After 40 more moves a draw was agreed. 1/2
