This model game, Bondarevsky–Smyslov (Moscow, 1946), turns on a single instructive error and serves as a counterpoint to the previous game's lesson on central majorities. From a Ruy Lopez with the delayed exchange on c6, White's natural-looking push e5 hands Black exactly what he wants: a knight blockade on e6 that freezes the central pawns and lets Black's bishop pair and queenside pawns take over. Smyslov then gives a model demonstration of positional play by restricting White's pieces, gaining space with g5, c5, and b5, and steadily converting an accumulation of small advantages into a winning endgame.
