White to move. Main line: 1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. Nc3 e6 5. e3 Nbd7 6. Bd3 dxc4 7. Bxc4 b5 8. Bd3 Bd6 9. O-O O-O 10. Qc2 Bb7 11. a3 Rc8 12. Ng5 c5 13. Nxh7 Ng4 14. f4 cxd4 15. exd4 Bc5 16. Be2 Nde5 17. Bxg4 Bxd4+ 18. Kh1 Nxg4 19. Nxf8 f5 20. Ng6 Qf6 21. h3 Qxg6 22. Qe2 Qh5 23. Qd3 Be3
Anand answers 13.Nxh7 with ...Ng4, ignoring the attacked knight to accelerate the attack. The central break ...cxd4 and bishop move ...Bc5 bring every black piece toward White’s king.
The sequence 16...Nde5 and 17...Bxd4+ keeps White under checks and threats. By 23...Be3, the bishops, queen and knight have built an inescapable mating net, so Aronian resigns before mate appears on the board.
This game is valuable for move-order study. The attack succeeds because central lines open exactly when the pieces are ready; copying a sacrifice without the preceding development would miss the tactical justification.
