[Event "FIDE Candidates Tournament"] [White "Caruana, Fabiano"] [Black "Alekseenko, Kirill"] [Site "Yekaterinburg"] [Round "2.1"] [Annotator "Stephen Gordon"] [Result "1-0"] [Date "2020.03.18"] [WhiteElo "2842"] [BlackElo "2698"] [PlyCount "67"] {A really impressive game from the world number two. Choosing a serve-volley approach with the f3 Nimzo, Caruana came very well prepared and it was really all one-way traffic when Alekseenko started to err from around move 15 onwards. Current games are suggesting that Black needs to have very deep preparation against 4.f3 to avoid falling into tough spots.} 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. f3 {The most uncomprimising variation against the Nimzo-Indian. White threatens to achieve a big pawn centre straight away, however Black has a number of different options in response.} d5 {Probably the most solid of Black's main three options} (4... 0-0 {Is possible but is likely considered slightly dubious at top level as very few elite players tend to go for this.} 5. a3 (5. e4 d5 $5 )Bxc3+ 6. bxc3 {Leads to very double-edged play. I think the current opinion is that this is quite risky for Black.} )(4... c5 5. d5 b5 6. e4 0-0 {is probably still considered the mainline. Both sides really need to know what they are doing here. An advert for White players is the following game played around this time last year:} 7. Nh3 bxc4 (7... d6 {is another line that requires serious consideration.} )8. Bxc4 exd5 9. Bxd5 Nxd5 10. Qxd5 Ba6 11. Bf4 Nc6 12. Kf2 Ba5 13. Rhd1 Nb4 14. Qd6 Re8 15. Kg1 c4 16. Bg3 Re6 17. Qxd7 Nd3 18. Qxd8+ Rxd8 19. Rab1 Ree8 20. Nf4 Nxb2 21. Rxd8 Rxd8 22. Nfd5 Nd3 23. Bc7 Bxc7 24. Nxc7 Bc8 25.

Kc7 {1-0 (48) Anton Guijarro,D (2643)-Nguyen,T (2546) Prague 2019.} )5. a3 Be7 {This line has become topical recently. It was used most recently by Vishy Anand to defeat the phenomal prodigy Alireza Firouja in Wijk earlier this year. Black's idea is to accept a space disadvantage in the centre, in return for dark-squared control.} 6. e4 dxe4 7. fxe4 c5 (7... e5 {is also playable in this position, but practice has shown that after} 8. d5 Bc5 9. Nf3 {White has a good game. Just one thing to note here - after} Ng4 {White can respond with} 10. Na4 {after which Black doesn't have a good follow-up.} )8. d5 exd5 9. exd5 0-0 10. Be2 $1 {A very important move order that White must use to maximise chances in this variation. The differences can be seen when looking into the options that Black has after the natural 10.Nf3.} (10. Nf3 Bd6 {In the position with the bishop on e2 rather than the knight on f3, 11.Nb5 is a good option for White. Here it falls short.} 11. Be2 (11. Nb5 Bg4 $1 { This is an issue for White - Black is gaining time on the e-file after} 12. Be2 Bxf3 13. Bxf3 (13. gxf3 {might actually be a better move, but White's position is not at all attractive.} )Re8+ $1 14. Be2 Be5 )Bg4 12. 0-0 Nbd7 13. Nb5 Bb8 $11 )Re8 (10... Bd6 11. Nb5 $1 (11. Nf3 Bg4 {is giving Black exactly what he is aiming for in this line.} 12. 0-0 Nbd7 {To me this looks fine for Black.} )Re8 12. Nf3 Bg4 13. 0-0 {In this version White looks to be slightly better due to it being awkward for Black to both keep the dark-squared bishop on the h2-b8 diagonal and get the queenside developed.} )11. Nf3 Bg4 12. 0-0 Nbd7 13. d6 $5 {Very uncomprimising. This must have been part of team Caruana's preparation. It looks strange at first sight to move the supported passer forward at this stage, but Caruana is of course aware that Black was one move off achieving an ideal coordination with ...Bd6.} (13. h3 Bxf3 14. Bxf3 Bd6 {is the sort of position Black is looking for in this line. Although White has a supported passed pawn and the bishop pair, Black has very nice central control, especially on the dark squares - and all of Black's minor pieces are healthy. In the long-term there could be some strategic risk in this for White. There are possible scenarios in which, if the position simplifies, White's light-squared bishop can end up being a prospectless piece. Of course that's some way off, but Black absolutely has a clear game plan here and I think it's the reason why players are turning attention to this line.} )Bf8 14. h3 Bh5 15. Nb5 Re6 $2 {Caruana's comments in the press conference suggested that he was happy to see this move, because he bishop belonged on f4 anyway. It's the first red flag raised by the engines.} ({Both} 15... Rb8 {and} )(15... Qb6 {were mentioned by Caruana as valid alternatives. Surely areas of investigations for players interested in playing this line from either side.} )16. Bf4 a6 {This is Kirill's idea behind ...Re6 - he's making sure to be able to answer Nc7 by hitting the loose bishop on f4.} 17. Nc7 Re4 18. Bh2 ({The engine suggests that White has a huge advantage after} 18. Qd2 Rb8 19. Rad1 {Black is really struggling to do anything about the thorn on d6.} )Rc8 19. g4 $5 {Fabi has been steam-rolling so far. This must have been extremely difficult for Alekseenko to face. By this stage he was already very low on time and he must have been questioning whether Caruana was still in preparation.} Bxg4 ({Black is ill-advised to try and keep the material balance. Taking a quick look at the squares that are available to the rook on e4 indicates that it's very likely some material is going to fall shorlty.} 19... Bg6 20. Bd3 Re3 21. Bxg6 hxg6 22. Qd2 Re4 23. Rad1 {is a sample line - White is fully coordinated and Black's pieces can barely move.} )20. hxg4 Nxg4 21. Bd3 {Again Fabi continues to force the pace, judging that the following simplification will be in White's favour.} Nxh2 {There's really no other option for Black. In some way it's a small victory that Black should now be able to round up the d6-pawn.} 22. Bxe4 Nxf1 23. Qxf1 Bxd6 {At a glance this may look ok for Black, but it really isn't. White's piece activity is fantastic and the major pieces are coming into play with a gain of time. Caruana felt that after 23...Bxd6 White is probably winning.} (23... Nf6 {was suggested by Caruana as a better alternative. The point being that now White isn't able to post the light-squared bishop on d5.} 24. Re1 {is the move Fabi indicated he would play} (24. Bf5 Rb8 {would still objectively be better for White, but Black has a much improved version of the game.} )Qxd6 (24... Bxd6 25. Nd5 )25. Nd5 Nxe4 26. Rxe4 Qg6+ {This from a distance could have put a lot of players off playing 24.Re1, but Caruana sees deeper.} 27. Qg2 $1 {after which} Qxe4 { is answered by} (27... Qxg2+ 28. Kxg2 $16 )28. Nf6+ )24. Nd5 g6 25. Qh3 Kg7 26. Kh1 Ne5 (26... f5 27. Bxf5 gxf5 28. Qxf5 {highlights the weakness of the Black king, which is being caused by how dominant all of White's pieces are. The black pieces just can't get over to the kingside to help.} )27. Nh4 $1 { Keeping the knight on the board - it's another dangerous attacking unit.} (27. Nxe5 Bxe5 {Would have let Black back in it.} )h5 28. Rg1 Bf8 29. Nf4 { The pawn cover for the black king is about to crumble.} Ng4 30. Nxh5+ gxh5 31. Bf5 Be7 32. Bxg4 hxg4 33. Qxg4+ Bg5 34. Qh5 $1 {Nice. Other moves end the game, but Fabiano finds the quickest way. A great game by Caruana. Energetic opening play and excellent judgement during the middlegame. Unfortunate for Alekseenko, who it seems was a bit ambushed by Fabi's opening, never really getting into the game. What can you do if your opponent just plays a phenomenal game?!} (34. Qh5 f6 {White forces mate after this. One sample line:} 35. Nf5+ Kf8 36. Qh8+ Kf7 37. Qh7+ $1 Kf8 38. Qg7+ Ke8 39. Re1+ )1-0
