Why Aronian Plays the English

In recent times I have taken a liking to this move. After all, in the main openings too much is already known, and contortions such as 1.d4 and, after any move, 2. Bf4 do not yet attract me. It only remains to rely on the openings of my early youth - the English and the Reti.

Annotated Game #187: Taking on the "Sniper" with a reloader tactic

(Note: this replaces a previous, duplicated Annotated Game #187)

In the following tournament game, my opponent uses the "Sniper" formation, which was popularized first in a 2011 book then a 2017 ChessBase DVD by FM Charlie Storey.  You can read in more depth about it in the previous links, but basically the idea is to have a system as Black with ...g6, ...Bg7 and ...c5 to meet all of White's options.  Since this formation is a component of some more mainline opening systems, it's not an entirely untrodden path in the opening, although it is an original approach.

Against the English Opening, I don't think the "Sniper" has as much bite, primarily because the key ...c5 pawn move for Black isn't as challenging when White does not yet have a pawn center built up.  Here we get into a Symmetrical English, which is not really what Sniper players are looking to do, and as White by move 9 I feel I have a comfortable, active game.

The turning point of the game is a "reloader" tactic that I spotted the potential for, involving a sacrificial knight fork on g5 that gains me a pawn and a lasting advantage, although I give it back temporarily before my opponent gets too greedy with pawn-grabbing and neglects his king position, allowing me to break through with tactics involving forks, pins and sacrifices.

Nf3 Bg7 3. Nc3 c5 {known as the "Sniper" formation. Without a pawn on d4, however, it does not have independent importance.} 4. g3 Nf6 5. Bg2 { now we're in more familiar Symmetrical English territory.} O-O 6. O-O d5 { a more aggressive continuation than maintaining symmetry with ...Nc6. I am fine with exchanging the central pawn and opening the h1-a8 diagonal, however.} 7. cxd5 Nxd5 8. Qb3 {the second most popular continuation in the database. I liked the idea of hitting b7 and getting my queen on a good diagonal early.} ( 8. Nxd5 {is more popular, for example in this game by Kramnik:} Qxd5 9. d3 Nc6 10. Be3 Bxb2 11. Rb1 Bg7 12.

The d4 square is dominated by Black, but I nonetheless have comfortable development.} Be6 {taking the diagonal for his own, but in the process blocking any idea of advancing the e-pawn.} 10. Qc2 h6 {taking the g5 square away from the Nf3 (and the Bc1). However, Black is starting to get behind in development.} 11. Be3 {developing and targeting the c-pawn, which is isolated from its natural support (the b-pawn) by the Nb6.} Qc8 12. Rfd1 { here I thought for a while, as I saw no obvious plan for White. The rooks seemed to be to be well placed on the d- and c-files, so I decided to continue development that way.} Rd8 {in order to oppose the idea of my advancing the d-pawn.} 13. Rac1 $14 {by this point Komodo gives White a small plus. I have all of my pieces developed, while Black's queenside remains partially undeveloped. The c-pawn also remains a target, which my opponent recognizes with his next move.} Na6 14. a3 {making sure the Na6 does not come into b4, and also removing the a-pawn from the Be6's pressure.} Bh3 15. Bh1 {the engine ranks higher pretty much any alternative to this move, which preserves the bishop. At the time, I felt that its influence over the long diagonal was worth maintaining.} (15.

My opponent did not see the threat on g5, however.} Qb5 $2 {neglecting protection of the now-hanging Bh3.} (17...

Rc1 {although now despite the material equality there is still a plus for White because of the a-pawn weakness, Black's more awkward piece placement, and the Bh1's influence. For example} b6 22. Ne5 Qe8 23. Bxa8 bxa5 24. Bc6 Qh8 25. Qxb2 Bxe5 26. Qb5 $14) 18. Nfg5+ { a genuine "reloader" tactic! The knight fork on g5 is repeated.} hxg5 19. Nxg5+ Kg8 20. Nxh3 $16 {now I am a clear pawn up with no compensation for Black. I also am eyeing Black's weakened king position.} Nd5 {making my next move choice with the Be3 that much easier.} 21. Bh6 Qxb2 22.

Rxb7 $16 {preserves the advantage, although it's not immediately obvious to a Class player (i.e. me) during the visualization/calculation process. The immediate threat is Ra1, winning a piece as both the Na6 and Ba3 are hanging. Black can avoid this, but the a7 pawn is also underprotected. Play could continue} Nab4 {(also protecting against Bxd5 followed by Rxe7)} 25. Bxd5 Nxd5 26. Ra1 Bb4 27. Raxa7 $16 {and I'm back to being a clear pawn up.}) 22... Bf6 $11 23.

Nf4 $16 {and the attack continues.}) (24... Qa4 {pinning the Be4 seems to be the best practical chance for Black.} 25. Nf4 Nxf4 26. Bxf4 $16) 25. Qh5 {after a good deal of thought, this seemed to me to be the best follow-up, taking advantage of the pinned g6 pawn. Komodo agrees.} Rh8 26. Qxd5 Kxh6 27. Qxf7 $18 {material is equal but Black's king is under heavy pressure.} Rag8 28. Nf4 (28. Qe6 {is the idea behind a quicker route to victory by repositioning the queen.}) 28... Rg7 29. Qd5 b6 $6 {protects against the pawn snatching threat, but neglects the king.} 30.

FT: Boxer Wladimir Klitschko - 'Chess is war with an army'

As I've highlighted on this blog several times in the past, the Financial Times (FT) periodically publishes thoughtful chess-themed articles and interviews, the most recent one being with heavyweight champion boxer Wladimir Klitschko.  The chess itself isn't the really interesting part, although Klitschko knows both Kramnik and Kasparov; rather, it's how Klitschko has incorporated it into his life and his outlook on competition and winning.  Here are a couple of the more interesting points from the article for me; the full interview (linked above) is well worth reading.
According to my opponent, there are some unlikely parallels between top-level boxers and chess players. His friend Kramnik told him that grandmasters “lose an incredible amount of weight during a tournament”. “Some tournaments,” Klitschko says, “are long. It shows how much energy and calories your brain can burn. They lose like, if I’m not wrong, during the two weeks or week and a half, up to 20kg. If they go to sleep, they cannot really turn off their mind. It’s just constantly doing combinations and combinations and combinations.”
In his book, he says that before any fight, he visualised the fighting style of his opponents while also imagining victory. He believes the same approach can work in any negotiation. “Internalise your winning pose,” writes Klitschko. “Save similar motivational pictures on your smartphone and have a look at them if you have doubts.”
The champ appears genuinely elated and takes a photograph of the final board to send to Kramnik. “It’s an exciting game because it’s a war with an army,” he says of chess. “It’s a lot of co-ordination, a lot of focus, a lot of endurance. You have to be really agile in everything you do. It actually fits well into sporting life, into business life, into private life, into anything. It just matches with my genes.”

Resuming training and posting in May

Although I'll check in from time to time, I expect that I'll be mostly offline here until late May, due to other pressing demands on my time.  I'll look forward to getting back to chess, for sure.

In the meantime, something to consider...

How to come back from the chess vacation?
