Anish Giri – David Navara
5th Gashimov Memorial; Şəmkir, April 25, 2018
Caro-Kann Defence B12

1. e4 c6 2. d4 d5 3. e5 Bf5 4. Nf3 e6 5. Be2 c5 6. Be3 Qb6 7. Nc3 Nc6 8. Na4 Qa5+ 9. c3 cxd4 10. Nxd4 Nxd4 11. Bxd4 Ne7 12. 0-0. If 12. Nc5 then 12. ... Qc7 13. g4 Bg6 14. f4 Nc6 15. 0-0 Nxd4 16. cxd4 Bxc5 17. Rc1 0-0 18. Rxc5 Qd7 19. Qb3 Be4 20. Rfc1 Rac8= Vachier-Lagrave – So, 2nd Gashimov Memorial, Şəmkir 2016. 12. ... Nc6 13. b4 Qc7 14. Rc1 Be7 15. g4!? Theory changes continuously. A recent game ran as follows: 15. b5 Nxd4 16. cxd4 Qa5 17. Nc5 0-0!? 18. Nxb7 Qxa2 19. Bd3 Bxd3 20. Qxd3 Rfc8? (better was 20. ... Rab8 in order to reply 21. Rc7 with 21. ... Bb4 22. Rfc1 Ba5) 21. Rc6!± Bok – Saltaev, 37th SchachBundesliga, Bremen 2018. 15. ... Be4 16. f3 Bg6 17. f4 Be4 18. Nc5 a5!? 19. Be3! axb4? The opening of the c-file will soon prove to be much more dangerous for Black than the a-file for White. 20. cxb4 Ra3 21. Bf2 Bxc5 22. Bxc5 Rxa2


23. b5? 23. Ra1 Rxa1 24. Qxa1 Kd7 25. Qa4 seems a more straightforward way of putting Black in a terrible bind. 23. ... Bc2?? Really a mysterious mirage. 23. ... Na5 was called for, even though after 24. b6 (24. Bd6 Qb6+) 24. ... Qc6 25. Rf2 Black should have had to find 25. ... Rxe2! 26. Qxe2 Nb3 27. Rc3 Nxc5 28. Qe3 0-0 29. Qxc5 Qa4 with full compensation for the Exchange. 24. b6. Sic et simpliciter. It looks like Navara was hoping for 24. Rxc2 Rxc2 25. Qxc2? Nd4!, but even in that case 25. b6 (instead of 25. Qxc2) would be a trivial win for White. 24. ... Bxd1 25. bxc7 Kd7 26. Bxd1 Kxc7 27. Bd6+ Kd7 28. Rb1 1 : 0.
