Learn How to Trap a Piece: London System Tactics
This London System puzzle shows how a seemingly active queen can become a liability when it overreaches into the enemy camp. The key idea is to recognize a trapped piece motif: one side’s queen has invaded, but the supporting squares and escape routes are limited. In practical classical chess, these positions often reward calm calculation over automatic recaptures, because the best move can force a decisive material gain by exploiting overload and poor coordination.
