Bishops Opening Calabrese Countergambit Deflection in Chess

In the bishops opening calabrese countergambit, “deflection” is the tactical idea of luring a key defender away from a critical square or line. Typically, after the countergambit’s early pawn sacrifice, White uses a forcing move (often involving the bishop or a direct threat) to make Black respond with a specific capture or block. The defining feature is that the defender’s relocation creates a new weakness—usually along the bishop’s diagonal or around the king-side dark squares.
