1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.d4 exd4 6.Qxd4 Qxd4 7.Nxd4 The exchange variation where White has an end game advantage because he can, in a pawn ending, create a passed pawn on the King side. In compensation, Black has the two Bishops and open files in the centre.  7...Bd7 8.Nc3 Bd6? Better to castle immediately  9.Nde2 O-O-O 10.Bf4 Bf8 Admitting that my 8th move was a loss of time.  11.O-O-O Ne7 12.Bg3 Ng6 13.Nf4 Gradually working towards and end game.  13...Nxf4 14.Bxf4 Bc5 15.f3 f6 16.Rd3 Better would be (16.h4 to stop Black's "minority" attack. ) 16...g5! 17.Be3 Bd6 18.h4 gxh4 19.Rxh4 h5! 20.Bf4 Be7 21.Rh2 Intending to double Rooks on the Rook file. As events prove (21.Rh1 would have been better ) 21...h4 22.Rd1 Rhg8 23.Rd2 f5! White's forces are going to be too mobile to exploit a passed King pawn.  24.e5 Rg6 25.Kd1

Bringing the King to release the Rooks from the defence of the backward pawn.  25...Rdg8 26.Ke1 Be6 27.a3 b6 28.Nd1 Kb7 29.Kf1 Kc8 30.Nf2 Bc4+ 31.Kg1 Bc5 32.Kh1 Bf1 33.Nh3 ( Not 33.Nd3 for  33...h3 wins ) ( nor 33.b4 Rxg2 ) 33...a5! Keeping the Bishop permanently placed on c5  34.c3 a4 35.Rc2 Kb7 36.Bc1 Rg3 37.Bf4 Kc8 38.Ng1 R3g6 39.Bc1 Rg3 Time pressure on both sides!  40.Nh3? Llorens in the Barcelona tourney book gives (40.Bf4 as necessary, though Black has a good game with  40...Rd8 ) 40...Rd8! 41.Rd2 Rxd2 42.Bxd2 Bxg2+ 43.Rxg2 Rxh3+ 44.Rh2 Rxf3! 45.e6 (45.Rxh4 loses a piece ) 45...h3 46.Re2 Bd6 47.Re1 Kd8 48.Bg5+ Ke8 49.Bf6 f4 50.Kh2 Re3 51.Rxe3 fxe3+ 52.Kxh3 e2 53.Bh4 Bf4 54.Kg2? (54.Be1 held out a little longer but the Queen side Pawns go. ) 54...Bd2 0-1

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.g3! e5 Opocensky's system, not so appropriate now White has played 6.g3 and can retreat his knight to e2  7.Nde2 Be7 8.Bg2 Be6 9.h3 Qc8 10.g4 Nbd7 11.Be3 O-O 12.Ng3 Qc4 13.g5 Ne8 14.Nf5 Bxf5 15.exf5 Nc7 16.f6! gxf6 17.gxf6 Bxf6 18.Be4 Bg7 19.Qg4

Threatening to win Black's queen  19...f5 20.Bxf5 Qxg4 21.hxg4 h5?? ( However, after 21...Nf6 22.g5 Black's position is markedly inferior ) 22.Bxd7 and won 1-0
