The Principle of Two Weaknesses: How to Beat a Solid Defence | Capablanca vs Lasker 1921

Capablanca beat the reigning World Champion with one quiet idea: when a single weakness won't fall, you make a second. Emanuel Lasker had held the world title for twenty-seven years. In the tenth game of their 1921 match, Capablanca - with the Black pieces - reached a position where White had just one weak pawn, comfortably defended. Most players shuffle here and offer a draw. Instead Capablanca manufactured a second weak pawn on the other wing, and suddenly Lasker's pieces could not guard both. Lasker himself called the play from move 24 on "enchanting." Capablanca called it the finest win of the match. Read the position before you read the moves. ♟️ One weakness isn't enough - White's isolated d-pawn was weak for twenty moves and never fell. A single, well-defended target does not win on its own. ♟️ Manufacture a second weakness - 31...a5! forces White to create a second isolated pawn on the far wing. Now there are two weaklings, a board apart. ♟️ One defender can't hold two - Chernev's verdict at move 36: the rook is "tied to the defence of two weak, isolated Pawns." 36...Ra6! gets behind them and one falls (44...Rxb3!). ♟️ Convert with precision - keep the more active rook, march the king up, and break with 64...e5! to make the passer. The technique that ended Lasker's last hope. This is the classic principle of two weaknesses - the idea, going back to Nimzowitsch, that one weakness is rarely enough to win against good defence, so you create a second and overstretch the defender. For the improver who keeps getting stuck in front of a solid position, this game is the model: tie the defender to one target, make a second somewhere else, and attack where he cannot bring enough force.
