Learn How to Remove the Defender: Decisive Material Gain
This chess puzzle is a classic middlegame example of removing the defender to win material. One piece is doing double duty: it protects a key square while also holding the position together. When that defender is exchanged, the follow-up tactic becomes possible because the remaining pieces are overloaded and the coordination collapses. In classical chess, these patterns often decide games without any need for a mating attack.
