Re: An idea I have... "semi-TT"...

I agree with you HG but I also think the idea of Bill is really interesting. I have thought of a related idea. My idea is a way of overcomming some of the problems with the history heuristics. The basic idea is to store a type of history heuristics for all (???) positions with a locked pawn structur...

Re: Outpost evaluation

Hi Michael!

I think you have a point :)
I have to fix my engine and test my ideas in code before I say too much.

Re: Outpost evaluation

Hi Lucas! I do not have a working chess engine right now so I have not been able to implement my ideas. I think an outpost should only be counted as an outpost if it cannot be threatened by a pawn. What I think is important is that you should give the knight outpost higher value the more pieces the ...

Counting depth as a function of number of legal moves

Hi all of you! This is my first post here even though I have read and enjoyed most of the threads in this forum for at least half a year. First of all I apologize that I do not know the computer chess terminology very well. I hope my idea is not too stupid. It has to do with how to count the depth o...
