Tarrasch Defense Rubinstein System Puzzle (Rated 1700): Win Material — Crushing Opening Tactic

This puzzle comes from the Tarrasch Defense and shows how a well-timed tactical shot can punish loose coordination in the middlegame. White’s active knight jumps into the enemy camp, creating multiple threats at once and forcing Black’s pieces into awkward defense. The key idea is that tactical pressure on the king, queen, and rook can outweigh simple material counting. When pieces are overloaded and key squares are weak, a forcing sequence can turn a balanced position into a winning material advantage.
