Trompowsky Attack Classical Defense Discovered Attack Chess Puzzles

In the Trompowsky Attack against the Classical Defense, White often starts with 1.d4 Nf6 2.Bg5, and a discovered attack can appear when a piece moves away to reveal a line for another attacker. The key feature is that the bishop on g5 and a hidden rook, queen, or bishop line can suddenly target a defended piece once the blocking piece shifts. For an intermediate player, this motif means using the opening’s early piece activity to create tactical pressure, not just to win the bishop pair.
