Kg2 $3 {[#] Instead of the 30.Qg5+ move played in the game, Stockfish 15 spat this Hidden Silent Move against my PC screen twenty-three years later. I couldn't believe my eyes and really thought I had set up and entered the wrong position (a notorious source of error moves in correspondence chess!). It is so counter-inuitive in this position to move with the King and then also move onto the white squares: the black Bishop's squares! Extreme prophylaxis: it takes the defensive maneuver Dd4 check out of the position to win; the black diagonal is more important.} Kf8 ({By the way, if black now makes his “saving” move} 30...
