Puzzle #242 solution:
Fischer - Dely, 1967. Answer by Coco:
a) White should take advantage of the pin on the d7-rook before black has a chance to castle and take advantage because it's up an exchange. Since black's king is in the center, it can be attacked from the center, the kingside, and the queenside. White should do this because it is easier to attack the black king in the center not when it's castled and then or before win a piece or mate.
b) Solution:
