The story behind the game
Black’s advanced c-pawn and active rooks appear to secure space, but White builds pressure against the central defenders. A bishop capture on c4 and a knight capture on d5 transform the position through a long exchange sequence. The surviving rook then uses the seventh rank to restrict Black’s pieces.

- Challenge the pawn that supports the opponent’s activity.
- Count defenders again after each exchange.
- A long liquidation can favour the more active remaining rook.
- Use the seventh rank to restrict the king and minor pieces.

Nd4 brings the knight into the central contest. White has doubled rooks on the d-file, while Black’s c-pawn occupies c4. The knight move prepares a change of squares before White captures that pawn. Compare Black’s replies and the pressure on d5 rather than judging the knight move in isolation.
Bxc4 removes Black’s advanced central pawn. Black answers with a6, attacking White’s knight on b5. White does not have to retreat immediately: a capture on d5 changes the whole exchange sequence. Compare forcing captures before responding automatically to the pawn attack.
Nxd5 starts a sequence of central exchanges. Both sides’ rooks can capture on d5, and White’s bishop finally recaptures there. Black then takes the other knight on b5 with the queen. Count that final capture as well as the central exchanges before assessing White’s surviving rook and bishop.
Rd7 uses the open file to restrict Black. The rook attacks the knight on b7 along the seventh rank and reduces the black king’s freedom. Black retreats the knight to d8 in the recorded continuation. White can then improve the queen and pawns while keeping the rook active.
Result: 1-0. The recorded score ends here; it does not imply checkmate.
