Hi Christophe, Wouldn't you be able to accomplish the same thing by beefing up your qsearch? You might sacrifice a small amount of full width search for the extra investment in a "tactical search". You could think of the full-width plies as "positional search" and the qsearch plies as "tactical search", if you want. That would seem to solve the problem you mention above, where the full-width search could see that it could get its queen into a good position, but it would never be viewed as the best move since the tactical search would end up at a position where the queens had already been exchanged. Am I thinking about this right? Or am I misunderstanding what you are trying to accomplish?
