60th ch-RUS Superfinal
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d6 6.f3
This is a little bit unusual in top GM games. Usually they choose the 6.Bg5 or 6.Bc4 6...e5 [Black can also choose 6...Qb6 7.Nb3 e6 8.Qe2 a6 9.Be3 Qc7] 7.Nb3 Be7 8.Be3 0–0 9.Qd2 a5 10.Bb5 Be6 11.0–0 d5 [11...Na7 12.Be2 Nc6 13.Bb5 Na7 14.Be2 Nc8 If black want to avoid draw. 15.Bb5 Nb6 16.Qf2 Nc4 17.Bxc4 Bxc4 18.Rfd1 Qc8 19.Na4 Nd7 20.Nd2 Be6] 12.exd5 Nxd5 13.Nxd5 Qxd5 14.Qxd5 Bxd5 15.Rfd1 (Dreev suggest 15. c4!? Be6 16.Nc5 Bxc5 17.Bxc5 Rfd8 as photo below) Bxb3 16.axb3 White has the pair of bishops 16...Nd4 17.Bd3 Bc5 18.Kf2 b6 19.Rac1 Rac8 20.Bc4 b5 21.Bd5 Rfd8 22.Bb7 Rb8 23.Be4 g6 Planning f5. 24.Ra1 f5 25.Bd3 Bb6 26.Ra2 Kg7 27.g3 b4 Black has a new backward pawn: a5 28.Re1
28...Rbc8 29.Bc4 f4 30.gxf4 exf4 31.Bxd4+ Rxd4 32.Kf1 Rd2 33.Re6?
This was the mistake. Moro lets Dreev rook dominated his second rank. [33.Re2!? and White could well hope to play on 33...Rxe2 34.Kxe2=] 33...Be3–+ 34.Rxa5 [34.Bd3 Rc5 Threatening Rf2+ and Rxf3.] 34...Rxc2 35.h4 Rd8 Black has a mate threat on d1! 36.Rd5 Ra8 Now threatening mate in two starting with... Ra1+ 37.Rd7+ Kh6 Black renewing his mate threat on a1. 38.Ba6 [Probably Moro didn’t want to be to defensive with 38.Be2!? but White actually can hope to live] 38...Rf2+–+ [38...Rxb2?! 39.Ree7 Rf2+ 40.Ke1] 39.Ke1 Rxb2 [39...Rxf3 Probably would be much better. Clearing the way for his passed f pawn . 40.Ree7 Rh8; 39...Rxf3 40.Ree7 Rh8 41.Bc4–+] 40.h5? [40.Ree7!? Attacking the h7 is better. 40...Rh8 41.Bc4 Bf2+ 42.Kd1 Bxh4 43.Rf7µ Creating a nasty trap 43...g5?? 44.Rf6+ Kh5 45.Bf7# mate.] 40...Rb1+ [40...Rxb3 might be the shorter path 41.hxg6 hxg6 42.Rd5–+] 41.Ke2? [41.Rd1 Rxd1+ 42.Kxd1 Kxh5 43.Ke2–+] 41...Rb2+ 42.Ke1 Rxb3 43.hxg6 hxg6 44.Rdd6 Rb1+ 45.Ke2 Rg1 46.Kd3 [46.Rd3 Rg2+ 47.Ke1 Ra7–+] 46...Rb8 47.Ke2 b3 48.Bd3 Exerts pressure on the backward pawn 48...Rg8 49.Re5 [49.Be4–+ the last chance for counter play] 49...Ra8 [49...Ra8 50.Ra6 Rd8 51.Rxe3 Rg2+ 52.Kf1 fxe3 53.Kxg2 Rxd3–+ Black passed pawns are to strong to handle.] 0–1
