I played a game against crafty15_20 two nights ago. Used craftys default settings, with no oppening book or endgame databases. Without any board representation other than "d" option on the command line. The computer is P II 450 with 128 MRam. 180K N/sec Why didn't crafty see the mate after 26. ... Qe7 (under normal conditions, i.e. 2-3min per move)?! How many other programs don't see that mate? BTW after 26. ... Qe7 17. Qg4 f6 crafty finds the mate in about 18 sec. In analize mode it takes something like 30 min or more for crafty to find that Qe7 leads to mate. At what point a program searches for mate instead of material gains? (I have the crafty code but haven't spend the time to learn it.)
