Would you like me to whip up a program that can see to depth 20 at just about any time control, even with slow hardware, yet still lose every game? FIRST you need the knowledge, THEN you work on speed. What's the point of getting to depth N if you are not able to properly evaluate a position at that depth? The best programs are not the best because they are the fastest. The King is, as you have noticed, relatively slower than most of the other commercials. Why is it as good as the other commercials then? The one MAIN point you have failed to take into account is that when The King reports a certain depth, it is reporting a MINIMUM search depth (unlike some other programs that report a MAXIMUM search depth), and many of the lines that it has searched have been searched WELL PAST that depth. Take a look at this post: http://www.talkchess.com/forums/1/message.html?240127 How do you think it is possible for The King to announce Mate in 11 (22 plies away) at depth 9? And, vice versa, there are probably several amateur programs available that are faster searchers than any of the commercials. Yet, why are they not as strong as the commercials? You continue to fail to see the flaw in your argument.... jm
