1)I do not find in the pseudo code in figure 3 undo null move. I assume that it should be before if value>=beta and after value=-search(...) Am I right? 2)What is the value of the research for tactical strength? Should it help significantly relative to searching to reduced depth when value>=beta without research (even when we get value that is less than beta). 3)What should be in the research? I think that only calling search with the original alpha and beta. My first thought was that I can do it at the end of the search but the problem is that at this stage I do not know alpha. Note that in movei I did not use (!verify||depth>1) because I do not do null move with depth=1 so this condition always happen. Uri
