Vassily Mykhaylovych Ivanchuk – Wesley So
77th Tata Steel Chess Tournament; Wijk aan Zee, January 18, 2015
Spanish C88

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. 0-0 Be7 6. Re1 b5 7. Bb3 0-0 8. h3 Bb7 9. d3 d5 10. exd5 Nxd5 11. Nbd2 Qd7 12. Nxe5 Nxe5 13. Rxe5 Nf4! Chuky was really expecting 13. ... Nf6 as in the game Anand – Aronian, World Chess Championship Candidates, Khanty-Mansiysk 2014? Then Wesley So said: “Actually, Levon [Aronian] told me he fired his seconds for not finding 13. ... Nf4”. 14. Nf3

14. ... Nxg2! 15. Kxg2 a5!! Threatening both ... a5-a4 and ... Ra8-a6. “It was analysed by @anishgiri in NIC 2014/3, which is yet another reason why everyone should subscribe to the world’s best chess magazine!”, Grandmaster Nigel David Short tweeted. 16. Rxe7? This is a panic move! After 16. a4 Ra6 17. Qe2 Rg6+ 18. Kh2 Bd6 White can hardly move, Guliyev – Gustafsson, Baden-Baden 2014. Giri’s main analysis ran 16. c3 Ra6 17. d4 Rg6+ 18. Kh2 Rf6 19. Ne1 (19. d5 Bd6 20. Kg2 Rxf3 21. Qxf3 Bxe5 22. a4 c6! is better for Black) 19. ... Rxf2+ 20. Kg1 Rf6 and Black keeps the attack alive. 16. ... Qxe7 17. c3 Ra6 18. d4 Rf6 19. d5 a4 20. Bc2 Rd8. White is probably already lost. 21. Qe1. More stubborn is 21. Qe4 Qxd5 22. Qxd5 Bxd5, but the ensuing endgame must be won by Black in the long run. 21. ... Qd7 22. Ng5 h6 23. Ne4 Rg6+ 24. Kh2 f5 25. Ng3 Qxd5 26. Qg1 Qf3! British Grandmaster Raymond Dennis Keene promptly showed, without any computer assistance, an elegant “dual”: 26. ... Rxg3!! 27. fxg3 (else 27. Kxg3 Rd6 28. Kh2 Rg6! 29. Qxg6 Qh1+ 30. Kg3 Qg2+ and ... Qg2xg6) 27. ... Qd2+ and wins. 0 : 1. The threat is 27. ... Rxg3 28. fxg3 Qe2+, and if 27. Be3 then 27. ... Qxe3! 28. fxe3 Rd2+ finis.
