Good to know that you don't loose your time like me. >There is a version for download but >it is not the latest version. I will lately try to look into what it is through Alta Vista engin. I hope that it is with graphics interface. I am not very used to engins. Only exception until now was Heiner's mate solver "Chest". There is simply nothing like this program for mate search anywhere. >The program simply play chess and also knows to read Fen. >The program is not supposed to be a mate solver. Then your program do perfect work! I doubt very much that mine will find mate in 11 moves, through what I call "material exchange" logic, at your time. > I have the >>impression that I never heard about this program.

So it should be by looking into what move give overwhelming material exchange. Probably few other way are possible. Mine mate solver don't look into material echange but only into fact or existence, or not of mate at given depth. MAte will be considered as found not when certain material is accumulated but when it reach position when one side is under check and have no moves to be done. >It is not at the level of the top programs and >I guess that it may get a rating of 2200 against humans. More that good! Would like to be there. >Part of the commercial programs like Junior7 >can do clearly better than movei in your position >but when I tried deep fritz >it crushed. It is normal for Fritz and many other programs. I was surprised when I found this. Certain program that are not so smart at playing chess but not alergic in solving mates. One of them is Chessmaster. >Junior7 can see the mate in 11 in only 35 seconds on p800 >(16 mbytes hash). >Blass,U - Junior 7 Is the Junior 7 some other version of your program, or Rebel Junior?
