Learn How to Win Material: Queen Sacrifice
This middlegame puzzle from the Modern Defense shows how a tactical queen sacrifice can convert activity into a decisive material gain. The key idea is that an exposed king and loose pieces can make a seemingly strong queen vulnerable to forcing exchanges. When the opponent’s queen is overextended, a forcing capture can open lines, simplify the position, and leave the defender unable to coordinate. In classical chess, these tactical refutations often decide the game before any endgame begins.
