Restrain, Blockade and Lose

This was Jose Raul Capablanca's European debut, and his invitation to San Sebastian 1911 was controversial before a single move was played: entry rules required a strong prior tournament result, and only Frank Marshall's personal vouching secured Capablanca's place over objections from other entrants. Capablanca beat Ossip Bernstein in round one and went on to win the whole tournament by half a point over Akiba Rubinstein, instantly establishing himself among the world's elite at the age of twenty-two.

This particular game, against Aron Nimzowitsch, carries a neat irony that chessgames.com's own title for it makes explicit: Restrain, Blockade and Lose. Nimzowitsch would go on to build his entire strategic philosophy around restraining and blockading an opponent's position, publishing the ideas in his 1925 book My System, but here it is Capablanca, playing Black, who restrains White's position and grinds him down, years before Nimzowitsch put the method into print.

The story that Bernstein formally protested Capablanca's eligibility before the event is treated by chess historians as an unverified rumour rather than a documented fact, and is included here only as reported background. The exact calendar date of round eight is also not confirmed against a primary tournament bulletin.
