Vienna Game Max Lange Defense Fork Puzzle (Rated 812): Crush with a Fork — Decisive Material Gain
This middlegame puzzle is built around a crushing fork that exploits king safety and loose pieces. Black’s knight jumps into the center with tempo, creating a direct check while also attacking a valuable target. The key idea is that the king’s limited escape squares force a response, and that response leaves another piece vulnerable. In practical classical chess, these tactical shots often appear when development and king safety outweigh static material balance.
