The story behind the game
The opening round of the 2013 Candidates leads to a compact lesson in active defence. Carlsen challenges the centre, takes a queenside pawn and then exchanges into a balanced rook-and-knight ending. The drawn result is less important than the move order: each exchange changes which squares Black needs to control.

c5 challenges White’s central space. White’s bishop returns to e2 and Black advances on the queenside. The central pawn exchanges later bring Black’s queen into play. Compare those active exchanges with a passive defence of the original pawn structure.
Qxb4 takes the pawn while opening a sequence of exchanges. White and Black exchange a-pawns on b5, then White offers a queen trade on b1. Black’s active bishop and rooks matter in the position after the queens disappear. Calculate that whole transition before deciding that the pawn capture simply wins material.
Ne5 centralizes the knight and challenges the bishop. White’s other knight moves to d4, and Black exchanges on f3 with check. A rook exchange on b1 follows. Track which minor piece remains for each side rather than treating all exchanges as equivalent.
g5 gains kingside space in the rook-and-knight ending. White answers with g4 and both kings improve. The drawn score still contains useful decisions about pawn contact, rook activity and knight squares. Check the opponent’s pawn breaks before copying the same space-gaining move in another ending.
Result: 1/2-1/2. The recorded score ends here; it does not imply checkmate.
