Zurich 1953 round 21: Boleslavsky vs. Keres

Paul Keres plays a novelty against Isaac Boleslavsky in the closed Ruy Lopez (the Chigorin variation). Boleslavsky finds himself worse after one inaccurate move and decides to give up the exchange to remove the raging bishops, but falls victim to the dancing knights. From the book “Zurich International Chess Tournament 1953“, by David Bronstein.
