Four Knights Game Halloween Gambit Deflection in Chess

In the Four Knights Game Halloween Gambit, White sacrifices material to accelerate development and create threats around the center and kingside. The “deflection” motif happens when White forces the opponent’s key defender to leave a crucial square (often by attacking it with a tempo or tactical threat), so a follow-up capture or fork becomes possible. A defining feature is the gambit’s tactical pressure that makes the defender’s job harder than usual.
