A [[Checkmate|checkmate]] with a [[Bishop|bishop]] and a [[Knight|knight]] against a lone [[King|king]] is delivered in the corner that can be covered by a bishop of the attacking side. For that reason a program ought to use a separate [[Piece-Square Tables|piece-square table]] for the position of the opponent king in order to drive it to the correct corner. [[Draw]] cases due to tactical loss of one of the pieces <ref>[http://www.talkchess.com/forum/viewtopic.php?t=45009&start=5 Re: Search with bitbase] by [[Joona Kiiski]], [[CCC]], September 05, 2012</ref> or the [[Stalemate|stalemate]] trap are left to the [[Search|search]] routine.
