Ke3 Kf5 1/2-1/2 I think your analysis misses a few interesting turning points in this game - at least one of them should be good for a testposition. Diep played on a Dual AMD K7 in this game, so no really big hardware although quite OK of course :). The position after opening and in early middlegame was unbalanced. At move 31 the position is about equal with probably a little advantage for Diep. Then Diep commited a horrible blunder 31...Rd1?? which should have lost the game: WARP - Diep [D]2r2nk1/p2q1ppp/1p1p1P2/4n1P1/2P4Q/2P4R/P2N2RP/4r1BK b - - 0 1 am Rd1 This one could be difficult for some other engines, too. You mentioned the next one, the awful 38. Qe8+?? which in my opinion already spoils the game to a draw ( although this would be very difficult to prove of course) WARP - Diep [D]3r3k/p4p1p/1p1Qn3/4nqP1/2P5/2P3R1/P5RP/6BK w - - 0 1 am Qe8+ This is probably an engine-specific problem, other engines probably have no problems here. Easiest looks Qf6+ with a sure win. Without diagram another maybe interesting one: WARP - Diep 8/p4pkp/1p2n3/4n1P1/Q1P5/2P3R1/P5RP/1q1r2BK w - - 0 1 am Qb3 Qb3 ?! isn't really a bad move but it looks quite senseless. If white wants to play c5 why not do it right now ? After Qb3 the queen is at a worse position for c5. But then there was also a rather brilliant move that might be a good testposition IMHO: WARP - Diep [D]8/p4pkp/1p2n3/2P1n1P1/8/1QP3R1/P5RP/2qr2BK b - - 0 1 bm Nf4 While the obvious 42. .. Nxc5 ?! might have been sufficient to hold after a long and dangerous fight, 42...Nf4 !! is clearly the best move, pretty, surprising, witty and a clear draw although very deep. The mainline to get this with drawscore should be something like 20 ply. Can your engine find this one, too ? Cheers, Peter
