I was impressed by Deep Fritz's result in one of the position from my correspondence games when Gandalf needed more than an hour when Deep Fritz could see the right move in a few minutes based on Enrique's post. >not for hiarcs (the more time the better) , not for shredder, I disagree here. I analyze positions with Shredder5 and I am not impressed Here is one example: [D]rn2kbnr/1bqp1ppp/p3p3/1p6/3NP3/2N5/PPP1BPPP/R1BQ1RK1 w kq - 0 1 This position is from my correspondence game(the game began 1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 a6 5.Nc3 Qc7 6.Be2 b5 7.0-0 Bb7 Shredder5 likes to play 8.e5(probably a bad novelty) I gave it a lot of time and Shredder needs more than 8 hours to find something better(Re1) It means that even p10000 is not enough for shredder to find Re1 at tournament time control assuming it has no book to use. The scores of Shredder5(PIII450(192 Mbytes hash) are Re1 +0.46 5:48 depth 12 e5 +0.47 6:22 depth 12(failed high) e5 +0.60 7:05 depth 12 e5 +0.48 12:39 depth 13 e5 +0.58 49:02 depth 14 e5 +0.40 93:23 depth 15 e5 +0.32 331:10 depth 16 Re1 +0.33 485:13 depth 16(failed high) I did not decide if to play Re1 or to play another move. Re1 is a sacrifice because black can win material by b4 and I have to analyze Nd5 and Na4 that were played in the past. Uri
