Modern Defense Three Pawns Attack Puzzle (Rated 991): Win with a Fork — Opening Tactics
This opening puzzle shows how a single active queen move can combine check, pressure, and material gain in one forcing sequence. White’s pieces are developed enough to exploit Black’s loose kingside setup and the vulnerable bishop on b2, which is overextended and difficult to support. In the opening, tactics often come from forcing moves that win time and expose undefended pieces. Here, the key idea is to use a check to pull the defender away from the critical square and then convert the resulting tactical weakness into a winning material advantage.
