Additional info: Also, I changed the late move reduction algorithm to make it more correct. Here is exactly what I do: 1. At any node - I first must try 3 moves before considering anything else. 2. Additionally, I try captures even if I've already tried 3 moves. 3. Otherwise,

DF: thanks for the link to this new (to me technique). I'll implement it soon. In my alpha/beta searcher a very simple minded version is actually working very well - it will take weeks though to test and refine this. The only thing I am doing now is: At any given node ... If

David, Just one comment on the ETC. This is not internal iterative deepening. Internal iterative deepening is a technique to find a high quality move that hopefully will give you a cutoff (when it gets searched.) It's a good technique to use but it isn't ETC. However, ETC will sometimes
