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)
