one more small advantage. If I am in check, I see immediatelly how many legal
moves I have left, and can extend if it is only 1 or 2 or whatever my flavor of
forcing check extension.

While with your type of legal move generation, the first move I try might be
indeed singular, but I dont know that yet since I falsely believe I have two
legal moves.

This is of course far less relevant if I do singular extensions or something
such which , of course, produces its own overhead
