Fully correct stealmate detection In the (rare) cases when the two conditions are true, then fully check again with a slow but correct MoveList<LEGAL>(pos).size(). This is able to detect false positives like this one: 8/8/8/Q7/5k1p/5P2/4KP2/8 b - - 0 17 When we have a possible simple pawn push that is not stored in attacks[] array. Because the third condition triggers very rarely, even if it is slow, it does not alters in a measurable way the average speed of the engine. bench: 8678654
