French Defense Rubinstein Variation Discovered Attack Puzzle (Rated 1225): Use a Discovered Attack — Tactical Advantage
This French Defense middlegame shows how a discovered attack can turn a cramped position into a decisive tactical win. White’s active piece placement creates a direct threat against the enemy king while also exposing a vulnerable piece on the h-file. The key idea is that one forcing move can do two jobs at once: give check, and open a line for another piece to win material. In classical chess, these double-purpose tactics often outweigh static material deficits.
