They extend pretty deeply even at small depths. >I doubt if the moves of Fritz are significant positional errors. Maybe not, but they do reveal that the positional knowledge of programs are basicly infantile. I do not think it is possible to be 2700 elo strong if you have such poor judgement of the position, this is why GMs only use programs to assist the tactical lines, they do not think much of them when it comes to positional understanding. >>Fritz killed me later on the king side, I can't hold the tactics, the best I can >>do is to get fritz to play 20 nonsense moves, but it always finds a tactical >>shot. > >If it finds a tactical shot then it means that maybe the moves are not nonsense. >There is a simple rule in chess that when your position is really bad you have >no opportunity for a tactical shot. True. Fritz position is not bad, but it takes a while for fritz to crack me open, GMs would be much faster at that. >> >>Of cause you can make it so, it is easy go give a higher score for positional >>gain, but programs do not know when it is correct to sac, you said yourself you >>disagreed with the program :) > >Humans also play sometimes wrong positional sacrifices. > >I gave the wrong move only as an example to prove that programs can sacrifice. > >Both humans and machines may be wrong or right in sacrificing but if I give >cases of a right sacrifice you may claim that maybe the program saw everything >in advance so it is not a sacrifice(something that is not always correct). Hehe, well maybe. I have however never seen a program sacrifice a bishop or knight into the opponents king position if it did not see the mate or material gain 10 moves later. -S. >Uri
