The whole game below. > New game 5rk1/1ppq1rb1/p2p1nn1/3Pp3/2P1Ppp1/PPN3P1/3BQPB1/2R2RK1 w - - 0 1 Analysis by The King 3.23: [P4 1.8/32 MB hash, CM9_UtzX new unpublished setting] 1.Rfd1 f3 2.Bxf3 gxf3 3.Qxf3 ³ (-0.55) Depth: 3 00:00:00 1.Rfe1 f3 2.Bxf3 gxf3 3.Qxf3 ³ (-0.49) Depth: 3 00:00:00 1.f3 fxg3 2.fxg4 Nxg4 = (0.18) Depth: 3 00:00:00 1.Qd3 Bh6 2.c5 Rh7 3.c6 Qg7 4.f3 fxg3 5.fxg4 Bxd2 6.Qxd2 Nf4 7.g5 Ng4 8.cxb7 Qxg5 ± (0.91) Depth: 3 00:00:00 = (-0.13) Depth: 13 00:02:54 24879kN (Utzinger, MyTown 25.12.2002) A typical but very good example where TheKing 3.23 is suffering from blindness. On the other hand: why should I increase king safety [so much as to get a realistic evaluation of the position] when the engine's overall strength becomes much weaker? I am not a programmer, but in such cases I wouldn't like to be one. Kurt Homepage Kurt & Rolf: http://www.beepworld.de/members39/utzinger
