Grob Opening Spike Attack Puzzle (Rated 1521): Win Material — Fork Tactics
This middlegame puzzle from the Grob Opening shows how active piece placement can create a decisive material gain. White’s queen and knight work together to exploit loose black pieces and the exposed king. The key idea is a forcing check that improves White’s activity while keeping the opponent’s king and defenders tied up. In positions like this, tactical refutation often comes from attacking two targets at once and using the opponent’s awkward piece coordination against them.
