Movei is a chess program that I developed. There is a version for download but it is not the latest version. The program simply play chess and also knows to read Fen. The program is not supposed to be a mate solver. I have the >impression that I never heard about this program. If this program look for mate >with some kind of extentions, or search for mate is done by some independent >segment in the program, like me program do. It simply searches for the best move like other normal chess programs. It is not at the level of the top programs and I guess that it may get a rating of 2200 against humans. Part of the commercial programs like Junior7 can do clearly better than movei in your position but when I tried deep fritz it crushed. Junior7 can see the mate in 11 in only 35 seconds on p800 (16 mbytes hash).
