Puzzle #257 solution:
Liu – Williams, X Chess Championship 2012. Brandon and Oliver common answer is the chosen one this time around:
"a) Even though if White moves Bb4 and pins the Black bishop, it's the wrong move because if White moves Rc7, it' s mate in one.
b) There is no answer for this question."
"1.Rc7#! ... This is a checkmate in one move. Finito, Kaput! The White bishop is protecting the rook and the Black bishop is pinned by the White rook and the pawn is blocking two of the escape squares. A surprising checkmate.”
