The Bad Mood

Viacheslav Diu – 韦奕 (Wéi Yì)
7th HDBank International Open Chess Tournament; Ho Chi Minh City, March 12, 2017
Queen’s Gambit Declined D44

“The most dramatic surprise of round two was the top seed 韦奕 (Wéi Yì) (China, Elo 2725)’s defeat to Viacheslav Diu (Russia, Elo 2421), which pushed Chinese Grandmaster down to 38th place with only 1 point”, reads today’s vietnamchess.vn report. 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 c6 5. Bg5 h6 6. Bh4 dxc4 7. e4 g5 8. Bg3 b5 9. Be2 Bb7 10. 0-0 a6 11. Ne5 b4?? An unfortunate novelty, giving White both time and squares. For 11. ... Bg7 12. f4 0-0 see Lputian – Sveshnikov, European Chess Club Cup, Yerevan–Chelyabinsk, Chelyabinsk 1991. 12. Na4 h5. A questionable corollary to the previous (bad) idea, evidently aimed to prevent Be2-h5. Black, however, does not seem to have particularly better moves; for instance: 12. ... Nxe4?? 13. Bh5 Rh7 14. Re1 with a devastating attack. 13. f4!+− Black is in a very serious mess, just to put it euphemistically. 13. ... h4 14. fxg5 Nxe4. 14. ... hxg3 15. Rxf6 would equally lead to a disaster. 15. Bf4! Bg7 16. Bxc4 0-0

17. g6! fxg6 18. Bxe6+ Kh7 19. Qg4 1 : 0. 韦奕 (Wéi Yì) must have been in a bad mood.
