Be4 Be4 is a bad move. 37.Qb6 is winning there because it goes to a won opposite bishops endgame (if you toss pieces with black) which directly explains why some programs want to make this move. Just tune higher in crafty for example opposite bishops, recompile and you'll see. Diep 1997 wanted to play Be4 too up to 10 plies. from 11 ply and further it preferred the better Qb6. Nowadays version has better opposite bishop code and prefers Qb6 pretty soon. There is only one shot in the deep blue - kasparov games (there are many in the log files visible though) and that's in game 6 where DB played Bf5! winning a queen. IN contradiction to what some non-analyzing dudes post here, nearly all programs play that move after seeing the same tactical line. Deep Blue plays it at 8(6). > >so far both of these moves have been found by two or more of todays >programs, in very short time. i can post more eval of both positions, if >requested. deep fritz does not choose these moves. my point was that >if deep fritz was able to choose these moves with a change in parameters, >then i would have to assume it would be capable to play these two moves >if the overall strength was not decreased from the change. > >junior7 >shredder5 >gandalf >goliath light >gambit tiger finds f4 not Be4 >these are just some that find these moves. > >conclusion: these two moves can be found by todays programs. > >kburcham
