In the game below, I belief that by dislodging c4 at move 32 should be a draw. As a human player one would consider c5/c6 etc as a viable option to defend against the queening threat by forcing the opponent rooks into a defencive position in order to trade the d4 pawn for it. It would be interesting to see craftys version after 32. c5 Crafty 19.15 - ParSOS [B50] WCCC 2004 Ramat-Gan (10), 12.07.2004 1.e4 c5 2.Nf3 e6 3.b3 d6 4.Bb5+ Bd7 5.Bxd7+ Nxd7 6.c4 Be7 7.0-0 Bf6 8.d4 Ne7 9.Bb2 Nc6 10.Na3 cxd4 11.Nxd4 0-0 12.Nxc6 bxc6 13.Bxf6 Nxf6 14.Re1 Rc8 15.Nc2 d5 16.exd5 cxd5 17.Ne3 Re8 18.h3 d4 19.Ng4 Nxg4 20.Qxg4 e5 21.Rad1 g6 22.h4 f5 23.Qg3 e4 24.Qf4 Qf6 25.f3 d3 26.fxe4 Qb6+ 27.Kh2 Qd4 28.Qe3 Qxe3 29.Rxe3 fxe4 30.Kg3 Rcd8 31.Kf4 Rd4 32.Rd2 (what was crafty calculating here?) for example: [ 32.c5 Kf7 ( 32...Re7 33.c6 Rf7+ 34.Ke5 Rd8 35.b4 Re7+ 36.Kf4 Rf7+ 37.Ke5) 33.c6 Ke6 ( 33...Re7 34.c7 Rxc7 35.Rxe4 Rd6 36.Ke3 Rcd7 37.Rd2) 34.Rxe4+ Kd5 35.Rxd4+ Kxd4 36.b4 Kc3 37.a4 d2 38.b5 Kc2 39.Rxd2+ Kxd2 40.a5 Rc8 41.Ke5 a6 42.Kd6 axb5 43.Kd7 Ra8 44.c7 b4 45.c8Q Rxc8 46.Kxc8 b3 47.a6 b2 48.a7 b1Q 49.a8Q] 32...Kf7 33.g4 Re6 34.Kg3 Rf6 35.g5 Rf5 36.Kg4 Ke6 37.Rd1 Rf2 38.Kg3 Rxa2 39.Kf4 Rf2+ 40.Kg3 Rf7 41.Ra1 a5 42.Kh3 Ke5 43.Kg2 a4 44.bxa4 Rxc4 45.Rae1 d2 46.Rd1 Kd4 47.Re2 e3 48.Rexd2+ 0-1
