How to win Sir Roger Penrose’s Chess puzzle (that computers can’t solve)


Despite chess computers being very highly rated and winning virtually all human grandmasters, there are still certain positions that the computers can’t solve.

Sir Roger Penrose has documented one of them here:

Chess engines will state that black is winning by a large margin, when in fact White can easily draw, or even win!

Drawing should be easy. Just move the king around (without moving the c6 pawn). The only black pieces that can move are the dark-squared bishops, which can’t checkmate your king.

Winning should be only possible if Black plays badly, e.g. Bishops all give up control of the c7 square. Then c7 followed by c8=B or c8=Q is checkmate!

Very nice study by Sir Penrose that illustrates the weakness of computers!
