It just means that even if there haven't been a capture or anything, I probe the
first two plys if there are just <= 5 pieces on the board. I guess there is no
reason to, if I have all 3-5 man tables. If there is <= 5 pieces on the board,
there _will_ be a hit at ply 1, and if not, there will only be a hit at ply 2 if
the move from 1 to 2 was a capture, which I already test for.

Right. But I was just describing what I did to limit probing in general. In this
case, it was not relevant.

Sure.
