PHILIDOR'S DEFENCE
(to) Albin / "Opera Box" Variations
White threatened 4.PxP to trade pawns and then queens (stopping Black castling), to gain by 6.KtxP.
Black defends his KP by a Queen's Bishop to KKt5(g4) pinning White's KKt. Strategically weak because an open B-for-Kt can ensue (best counter is 3..Kt-Q2), but can lead to a famous game. B-Alt.
     White  Black
 1.  P-K4   P-K4
 2.  Kt-KB3 P-Q3
 3.  P-Q4   B-Kt5?! Transp.from Zukert.
WHITE to Move or Undo or Jump or Clear
