On the Commentary in Chessbomb, GM Delchev mentioned a game of his (he was white) from 4 years ago:
Quote:Qc2 Re8 Rare move for the Top Level. I met it for the first time 4 years ago in one of my games, when I considered it as an interesting novelty.
10. Bg5 Be7 Impressive Novelty by Carlsen (In my game there followed 10... d4 11. Bxf6 (11. O-O-O e5 12. exd4 Nxd4 13. Nxd4 Bxd4 14. Nb5 Bg4 (14... Qb6) 15. f3 Be6 16. Kb1 a6 17. Nxd4 exd4 18. Qd2 was played before in Ernst, S-Hoeksema,H /Hoogeveen 2004/ and I believe this is the best for white, although I was then afraid to play this sharp move) 11... gxf6 12. exd4 Nxd4 13. Nxd4 Qxd4 14. Bd3 Qe5+ 15. Kf1 Kg7 16. Re1 Qc7 17. b4 Be7 18. Re3 f5 19. g4 f4 20. Rh3 h6 21. Rh5 Rd8 22. h4 Qd6 23. Rh3 e5 24. Bf5 Be6 25. Qe4 f6 26. g5 and white won with direct attack in Delchev-Elbilia 2010 /French gOP 16/. I had the impression that somewhere around move 14 black may considerably improve their play)
Anyone know of this game? It is probably not in databases?
