I played a few Fischer Random games between CM9000 and Genius 7 and decided to test the "learning" feature of Genius 7. All fives games were started from the same position. Notice in the first game how Genius is crushed (mate was announced in 16 by CM9000 around move 29). In game two at move 22 Genius as black decides on 22...fxe5 instead of 22...Qe8 but is still crushed a few moves later. In game 3 Genius 7 tries 22...Ng5 although Chessmaster sees a pawn plus advantage several moves prior to move 22. In game 4 Genius 7 decides to wait until move 23 and to change from 23...Ke8 to 23...Qe8 and once again gets crushed a few moves later. In game 5 Genius 7 waits until move 24 to change 24...Qf8 to 24...b5. Again same result a few moves later with a crushing defeat for Genius 7. It seems the crude attempt of Genius 7 to "learn" from its mistakes are laughable since its position has already been lost according to CM9000. It could continue to make minor move variations and would probably lose the next 20 games in a row doing this. The fischer random starting position basically forces both programs to play without an opening book and shows one reason why a good opening book is vital to a program. I understand Genius has a learning feature that is not tied to the opening book but attempts to vary it's moves when it starts having a losing score. Wouldn't it be much more effective to tie the learning feature in so that when a loss occurs the program refuses to play the exact variation of that particular opening in which the loss took place? I know that playing with opening books, games aren't duplicated like they would be with fischer random chess but in a long match that might be found at SSDF it seems CM9000 would be at a tremendous disadvantage if there was no mechanism to stop playing losing lines against other programs. The flip side of this little experiment is if a position was started and Genius won the game then Chessmaster would be on the losing side every single game.
