 It's plain that Chess Tiger has evaluated incorrectly the endgame, thinking
White is winning. Human chess players know that rook+pawn are often stronger
than two minor pieces, as the rook becomes increasingly agile at the endgame.
 It would be interesting to know what other engines have this evaluation bug sas
well.
