The story behind the game
This drawn 2013 Candidates game is useful for studying active defence without a dramatic final tactic. Aronian challenges the centre as the queens face each other along a diagonal, then keeps the rook active in the ending. The final rook exchange leads to a balanced knight position; the lesson asks which exchanges preserve activity rather than promising a forced win.

c5 challenges the centre and uncovers the queen exchange. White takes on a8, Black recaptures with the a7-rook and the central pawns are exchanged. The simplification preserves active squares for Black’s pieces. It is one supported route among several saved candidates, not a claim that every queen exchange is automatically safe.
Nd3 improves the knight while attacking the bishop. Black retreats the bishop to f8, and a pair of rooks is exchanged on c8. White then uses the b-file to recover a pawn. The activity of both sides matters more than an isolated tempo: follow the available files and pawn targets after each exchange.
Ke7 brings Black’s king into the ending. The rook remains active on the second rank while the knight helps guard central squares. White can expand with e4 and f3, so Black needs active coordination rather than a passive defence of every pawn. The saved lines retain a near-level evaluation.
Rc5 offers a supported rook exchange. White captures on c5 and Black’s knight recaptures. The recorded game ends after White’s next knight move as a draw. Compare the resulting king, knight and pawn activity; an engine score near zero is supporting evidence, not a mathematical proof of a draw.
Result: 1/2-1/2. The recorded score ends here; it does not imply checkmate.
