SICILIAN DEFENCE - Rossolimo Var.
(to) Noah's Ark Trap
Black's pawn to QR3(a6) attacked to dislodge White's bishop - an inferior move (here tending to favour White, unlike in the Morphy Ruy Lopez), it assisted a trap but was better delayed.
White's Bishop retreats disastrously to the QR-file (the a-file), trying to maintain the half-pin. W-Alt.
