When I lose a game of chess, I tend to know exactly where it went awry. Take the following position, where I faced Alireza Firouzja at the XTX Markets London Chess Classic, held at the Emirates Stadium in December. Firouzja, rated in the world top ten, was the top seed at the Elite section, and his canny middlegame play had taken me out of my comfort zone. In the position below, my first instinct was 21 Bxd5, but I was nervous: after 21…Nxd5 22 Qxe5 Bd6 23 Qd4 his active pieces, and my wayward horse on a5, seemed to offer ample compensation for the sacrificed pawn. But then the thought crossed my mind – why trade off my bishop at all? Before I knew it, I had played a howler.
