Micro-optimization for SEE: remove a superfluous condition This condition can never be true, it's superfluous. It never triggers even with a bench 16 1 20 run. To met the condition it would imply that the previous recapture was done by a higher rated piece than a Queen. This is only the case when the King recaptures and that's already handled in line 1161: (return (attackers & ~pieces(stm)) ? res ^ 1). closes https://github.com/official-stockfish/Stockfish/pull/5839 No functional change
