24. Ng5!!?? 24. Rh4+− was now very strong, but Basso gets tempted by something more exciting, even if not flawless to the engine’s further check. 24. ... Nxh1 25. Qb3 Be8? 25. ... Qf2! should hold everything together, even if by a hair’s breath (26. Bb5 Ng3). 26. d7!+− Qxe7 27. dxe8=Q+ Qxe8 28. Bb5 Qe7

Regardless of how the tournament ends, Basso can consider himself lucky he can enjoy such an interlude from the emptiness of lockdown at Tegernsee. Photo: schach-tegernsee.de.

And Then There Were None

Pier Luigi Basso – Ashot Parvanyan
Tegernsee Masters 2020; Bad Wiessee, November 1, 2020
King’s Indian Defence E81

Just like in an Agatha Christie novel, today German chess prodigy Vincent Keymer was ordered by the Mainz health authorities to leave Bad Wiessee and undergo a two-week precautionary quarantine at home, because only a few days before the tournament’s start, he was seated in the same classroom for examination with a classmate who then tested positive to COVID-19. The young Grandmaster, though feeling well and healthy, could do nothing else but return home. 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f3 0-0 6. Nge2 a6 7. Be3 b5 8. Qd2 Nbd7 9.

Black could sacrifice a second Pawn — quite in Morphy’s style — by 12. ... d5! 13. exd5 e4! with excellent compensation. 13. Nec3 exd4 14. Qxd4 Nc5 15. b4 Ne6 16. Qd2 c5? The exchange of Queens leaves White with a much better endgame. Probably best was 16. ... Qe7 and if 17. a4 then Black can effectively reply 17. ... c5 with good equalising chances. 17. bxc5 dxc5 18.

26. g3? White groundlessly fears the check at f4, thus giving Black precious time to set up a defence. 26.

King’s Indian Defence E97

1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 0-0 6. Be2 e5 7. 0-0 Nc6 8. d5 Ne7 9. b4 Nh5 10. Re1 f5 11. a4 Nf4. A questionable variation. 12. Bf1 fxe4 13. Nxe4 h6!? A novelty, but no improvement on 13. ... Bg4 14. Ra3 a5 15. bxa5 Rxa5 16. h3 Bd7 17. c5 which quickly led to a strategic win for White: 17. ... Bf5 18. cxd6 cxd6 19. Bd2 Rxd5 20. Bc4 Kh8 21. Bxd5 Nfxd5 22. Bg5 Bxe4 23. Rxe4 Qc8 24. Rb3 Nf6 25. Bxf6 Rxf6 26. Reb4 Nc6 27. Rxb7 h6 28. Qd5 Kh7 29. a5 Nd4 30. Rb1 Nxf3+ 31. gxf3 h5 32. Kg2 Qf5 33. Qe4 Qg5+ 34. Kf1 Rf4 35. Qd5 Qf5 36. R7b4?

Nielsen – Korobov, MrDodgy Invitational Blitz Knockout Blitz Chess Tournament, chess24.com, June 12, 2020, match game 1 (time control: 5 minutes without increment). 14. Ra3 g5. 14. ... a5 15. bxa5 Rxa5 16. Bd2 is also much better for White.


15. h4! gxh4 (15. ... g4 16. Nh2) 16. Nxh4 Nexd5 17. Ng6! Nxg6 18. Qxd5+ Kh8 19. c5! Of course, Black’s extra Pawn counts for nothing because of White’s overwhelming position (and Black’s shattered Kingside). 19. ... Ne7 20. Qd1 d5 21. Ng3 e4 22. Nh5 Nf5 23. Nxg7 Kxg7 24. Rh3 Be6 25. f3 Kh7 26. Qd2 Qf6 27. fxe4 dxe4 28. Rxe4. Now Black cannot even console himself with a Pawn. 28. ... Rad8 29. Bd3 (Δ Re4xe6) 29. ... Kg8 30. Bb2 Qg6 31. Qe2 Ng3


32. Rxg3! A final brilliancy, leaving the stage to White’s Bishop pair. 32. ... Qxg3 33. Re3 Qg4 34. Rxe6 Qxe2 35. Bxe2 Rd2 36. Bc3 Rc2 37. Rg6+ Kh7 38. Rg7+ Kh8 39. Rg3+ 1 : 0.
