Fruit cannot see advantage for black by 26...Rag8 27.Nxa7 Note that black could get equality and maybe more than it by other means. 34...Bf6 probably lead to equality but draw does not justify 26...Rag8. 27...Qh7 28.Nc6 g4 29.hxg4 Bh4 30.Qc3 hxg4 31.fxg4 R8g7 32.Qh3 Bxf2+ 33.Bxf2 Bxg4 34.Bxg4 Nxg4 35.Qxh7+ Rxh7 36.Re1 Rgh6 37.Kf1 Rh1+ 38.Ke2 R1h2 39.Kf3 Nxf2 40.Rxf2 ² (0.26) Depth: 19/53 00:23:11 798200kN (, 21.11.2005) Hydra - Kasimyanov, II Man vs Machine, Bilbao 2005 6rk/6q1/npNp2r1/2pPp2b/1PP1PR1b/P1B4P/1R4P1/5QK1 b - - 0 1 Analysis by Fruit 2.2.1: 34...Bf6 35.Rf5 Qh6 36.Ra2 R8g7 37.Kh1 Bg4 38.Bd2 Qh4 39.Be1 Qh6 40.Bd2 = (0.00) Depth: 16/40 00:01:49 69969kN (, 21.11.2005)
