Learn How to Fork: Tactical Refutation
This middlegame puzzle comes from the Bird Opening, specifically From's Gambit, where one active bishop and queen coordination create a forcing tactical refutation. The key idea is a fork that also works as a skewer: the attacking piece checks the king while simultaneously targeting a major piece and a loose defender. Because the position is already tactically loaded, the best move is not a quiet improving move but a forcing one that wins material and keeps the initiative.
