So, Wesley - Grandelius, Nils
Rd. 4
Nimzo-Indian Classical Noa
1. c4 e6 2. Nc3 Nf6 3. d4 Bb4 4. Qc2 d5 5. cxd5 exd5 6. Bg5
First of all, the line is popular not because it gives White an opening advantage but because it leads to very sharp play where one misstep can lose.
6... c5
Very sharp opening play by Black. Grandelius is also very young and as can be seen in this game, must have burnt the midnight oil for this encounter.
7. dxc5
Surprisingly, this is the best move.
7... h6 8. Bh4 g5 9. Bg3 Ne4 10. e3 Qa5 11. Nge2 Bf5
Despite appearances, White is actually enjoying a slight plus in this position.
12. Be5 O-O 13. Nd4 Re8 14. Bxb8
Here, 14. Nxf5! is stronger. 14... Rxe5 15. Nxh6+ Kg7 (15... Kf8! 16. Bd3 Nxc3 17. O-O Ne4 18. Bxe4 dxe4 19. f4 and White has a winning attack against the King.) 16. Ng4 Re8 17. Bd3 Nxc3 18. O-O Ne4 19. a3 Qxc5 20. Qd1 Bd2 21. Bxe4 Rxe4 22. h3 Ba5 23. b4 Bxb4 24. axb4 Rxb4 25. Rc1 Rc4 26. Rxc4 dxc4 (26... Qxc4 27. f4 with a strong attack) 27. Qd8 and Black is unable to develop his pieces and the White Rook will soon join the attack.
14... Nxc3 15. Nxf5 Ne4+ 16. Kd1 Raxb8
17. Nxh6+?
Either White is not familiar with the variation or he might have mixed up the moves. 17. f3! is enough for a draw. 17... Rbc8! 18. fxe4 Rxc5 19. Nxh6+ Kh7 20. Qf2 dxe4 (20... Kxh6? 21. Qf6+ Kh7 (21... Kh5 22. g4+ Kxg4 23. Rg1+ Kh5 24. Qxg5#) 22. Qxf7+ Kh6 23. h4 and White wins.) 21. Qxf7+ Kxh6 22. Qxe8 Rd5+ 23. Kc2 Qc5+ 24. Kb3 Qxe3+ 25. Ka4 Ra5+ 26. Kxb4 Qc5+ 27. Kb3 =.
17... Kf8!
Tucking in the King from a possible check.
18. Bd3
From the frying pan into the fire.
The alternative 18. f3 is only slightly less worse. White still has a difficult game.
18... Rbc8! 19. fxe4 dxe4! and White is a piece up but his King is dancing in the center.
18... Rbc8 19. Qe2 Rxc5?!
Missing a faster way to win: 19... Qa4+! 20. Bc2 (20. b3 Qc6!) 20... Qd7 21. f3 Rxc5 and if now 22. fxe4 dxe4+ 23. Kc1 Rec8 24. Rd1 Qc7 with mate to follow soon.
20. Qh5 Qa4+
21. b3?
The only chance lies in 21. Ke2! Understandably, the long walk by the King is not for the timid. 21... Rc2+ 22. Kf1 (The only move.) 22... Rxf2+ 23. Kg1 Bc5 24. Ng4 Re6 25. h3 Rf4 and Black's attack continues. But compared to the actual game continuation, it is easier here for Black to make a mistake.
21... Qd7 22. Ke2 Qe6 23. Rac1 Qf6 24. Ng4 Qb2+ 25. Kf3 Re6 26. Rxc5 Rf6+ 27. Nxf6 Qxf6+ 28. Kg4 Qe6+ 29. Kf3 Qf5+ 30. Ke2 Qxf2+ 31. Kd1 Qd2#
Of course, Wesley saw the mate coming
