And if in each ply we see only around 2, 3 or 4 moves, your logic Alpha-beta does not visit positions twice. I don't know what you're talking about when you say "we see each ply two times" and "first search." I only do one search. (Unless you count iterative deepening.) >metioned before.

This is probably derive from the logic that checking moves must go You can't have the advantage and the disadvantage at the same time. >only around 2, 3 or 4 moves (very often just one move).
