Hi, [...] >>>fast up to mate in 18 assuming many move are checks. In this position, CM6000 >>>took 58 seconds to see the mate but when forced to move announced "MATE IN 8". >>>If given several minutes to analyze the problem it correctly anounced "MATE in >>>5". >>>White to move - mate in 6 >>> >>>5N1R/5R2/5N2/K4k2/5p1p/1PB4b/2pp1P2/2bq4 w >>I set up this position (as above) 5N1R(rank 8) to bottom (rank 1) and my CM6000 >>says no mate found in about 3 secs - assume this position is correct as Caps >>are black. > >No, the position is correct as written. White is upper-case. As he said above, >CM6k took about a minute to find the mate, whereas you only let it search 3 >seconds. > >Crafty 16.3(modified) takes slightly longer to find the mate: > >8 1:29 Mat06 1. Rb7 Bf1 2. Rbh7 Be2 3. Rd7 Bc4 4. > bxc4 f3 5. Rd5+ Kf4 6. Rxh4# > >It finds the mate here, but takes until 2:09 to verify it. I gave this position to CM4000 on my Mac. It found the solution after 115 seconds (with score 99.94). When forcing it to move it moves Rb7 and announces "Mate in 5". cu, -daniel
