White’s pieces are already aimed at the enemy king, and the key defender is overloaded by tactical pressure on the e7 square. When a king is stuck in the center and the surrounding pieces are pinned or trapped, even a material deficit can disappear in one move. In classical chess, these patterns often reward active pieces over raw material.
