Learn How to Spot a Tactical Refutation: Decisive Material Gain
This puzzle comes from the Englund Gambit and shows how a seemingly active position can collapse when one piece is left undefended. White’s extra material looks comfortable, but Black has a forcing tactical refutation based on king safety, a discovered attack, and the vulnerability of the white queen’s back rank. In classical chess, these patterns often appear when development is incomplete and one side’s pieces are lined up on the same file or diagonal.
