French Defense Knight Variation Mate In 2 Puzzle (Rated 1270): Spot Interference — Mate in 2

This middlegame puzzle shows a classic interference motif: one piece is placed so it blocks a key defensive line and leaves the king exposed. In positions like this, the attacker often has a bishop and knight working together to create a mating net, especially when the enemy king is stuck in the center. The idea is not just to give check, but to force the defender into a square where the final attack becomes unavoidable.
