King valid move performace problem #3
Description
Whenever a king can move to an opponent attacked square it take a lot more
time to process.
To reproduce: set the maximum depth and maximum limit of depth to 1 and
place a piece so that it attacks squares where the engine's king can move.
You will see it takes a few seconds to decide on the move. At 1 depth the
decision should be instantaneous!
