This puzzle is a classic middlegame mating net built around a discovered check. White’s queen and knight already create heavy pressure around the black king, but the key idea is to open a line so a bishop can give check with tempo. Once the king is forced to respond, the queen joins the attack on the h-file for a forced finish. These are the kinds of patterns that appear in classical chess and in sharp supergm tactics alike.
