I do not complain about using book and I believe that at least in part of the games movei is not going to have significant problems in book positions unless tiger use aggresive learning and repeat the same opening that movei blunders again and again but if you do not repeat the same time control again and again then there is a hope that even aggresive learning is not going to help tiger. The main problem of movei is the fact that your palm is 70 elo better that the palm that Jorge used when movei does not use a significantly faster computer. I expected movei to have some chances after seeing that faile could score 1.5/2 against palm tiger inspite of the fact that palm tiger beated stronger programs and the fact that movei won a tournament when monarch and the baron played also encouraged me to send movei for testing but even on Jorge's hardware I evaluated palm tiger as favourite to win a match. movei may have more chances after I do a significant improvement in the search rules and some improvement in the evaluation but I am afraid that at that time the palm is going to be significantly faster because of better hardware relative to the hardware that it is using today so it can win the match again.
