It knows that it should not go forward with the king except endgame thanks to piece square table but not more than it. Note that I do not try to teach humans to play chess but to teach my program to play chess better. I plan to teach it about king safety in the future but today I improve it by other ways. I do not like to teach it simple ideas like no pawns near the king are bad(a lot of amateurs use this rule for their program) because there are cases when it is not bad. Maybe I can get some improvement by this rule but I do not like writing evaluation code only to delete it later. inspite of lack of knowledge Movei has chances against everything and recently it drew a blitz game against ruffian(the best freeware program) and it was not a grandmaster draw. see http://www.geocities.com/cpf27/page9.htm for the tournament and you can download the games(The movei that was used there is not the latest movei but it is clearly better than the public version) Uri
