Nc3 e5 {This is an Old Indian which is a sound opening, but not seen much.} 4. d5 ({The inviting} 4. dxe5 dxe5 5. Qxd8+ Kxd8 6. Bg5 c6 7. O-O-O+ Kc7 {is a well-known position that white scores less than 40% from in Mega_DB_2015.}) 4... Nbd7 5. e4 Nc5 6. Qc2 a5 7. Be2 {This was the first critical position. Will GM Ivanov play ...Be7 and keep the game in less chartered waters or play ...g6 and head to regular King's Indian Defense positions.} g6 {Whew, glad to see book.} 8. Nf3 Bg7 9. O-O O-O 10. Bg5 h6 11. Be3 {I have reached this position 6 times in OTB play, once in postal and many times in blitz. The normal way of arriving at this position is 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Be2 e5 7.d5 [More common is for White to play 7.0-0 when Black usually plays 7…Nc6 8.d5 Ne7 with three main moves for White 9.Ne1, 9.Nd2 and 9.b4] 7…Nbd7 (or 7…Na6) 8.0-0 Nc5 9.Qc2 a5 10.Bg5 h6 11.Be3 is the position in the game.} Nh7 {Now Black has the traditional KID idea of moving the Nf6 and pushing the kingside pawns as Ivanov did in this game. Other moves with this idea are 11…Nd7 or even 11…Ne8. The moves 11…Nh5 almost forces White to play 12.g3, but has the downside of making 12…f5 more challenging because the knight on h5 can be left hanging if Black wants to respond to 13.exf5 with gxf5.} (11...

Nxe5 Nxd5 15. cxd5 ({ In my only time facing ...Ng4, I played} 15. Rad1 $6 {1-0 (33) Carter,D (2175) -Asaro,J (2000) South Burlington 2012}) 15... Bxe5 16. f4 Bd4+ 17.

However, this move allows} 12. Nd2 {and White's pieces are well positioned and cannot be hassled from g4 or h5 without allowing White to rid himself of his "bad bishop" and reduce Black's attacking pieces on the kingside.} Bg4 ({The other try is} 12... Ng4 13. Bxg4 Bxg4 14. b3 {Only 7/93 games in Mega 2015DB;} ({I did not think} 14. a3 {was as good as 14.b3, after} a4 15. Bxc5 bxc5 16. Nxa4 Qg5 17. f3 Bd7 18. Nc3 h5 19. Nb5 Bh6 20. Nb1 $14 {with a plus for White, but not that easy a move to find OTB.}) 14... Bd7 15. a3 f5 16. f3 ({I was surprised to see Rybka liked} 16. exf5 {slightly better than 16.f3} Bxf5 (16... gxf5 17. f3 $14) 17. Nde4) 16... f4 17. Bf2 g5 18. b4 Nb7 19. c5 $6 {Too fast. Better to build up with Rfc1 or perhaps Nb3} bxc5 $2 ({Black should have played} 19... axb4 20. axb4 dxc5 21. bxc5 Nxc5 22. Bxc5 bxc5 23. Na4 $11) 20. bxc5 {Now the a-pawn becomes weak} Nxc5 21.

Well, I'm not sure I can play much better than I did here. GM Ivanov was not at his best, of course, but after 11 losses it felts very good to win one.} 1-0
