French Defense Burn Variation Puzzle (Rated 1063): Crush with a Deflection — Chess Puzzle with Theory & Hints

This middlegame puzzle is a classic example of a crushing tactical sequence built on deflection and discovered attack. One defender is pulled away from a critical square, and that creates a direct line for a heavier piece to strike with tempo. The key idea is not a slow positional squeeze, but a forcing combination that wins material by exploiting overloaded defenders and a pinned piece on the d-file. In practical play, these are the moments where classical chess calculation pays off.
