Reversed Sicilian - The Antidote of 1.c4
GM Boris Avrukh
Every chess player has faced the dilemma of how to meet the English opening.
1.c4 is objectively a weaker move than 1.e4 or 1.d4, but it is by far the trickiest option for White on move 1. With so many transpositions, different setups and move orders, White has plenty of options to turn the game into the desired setup.
That’s why we are pleased to announce this database in which one of the top theoreticians in the world – GM Boris Avrukh, provides you with a complete, aggressive repertoire against 1.c4.
Black has many choices after 1.c4, but the Reversed Sicilian (1…e5) is by far the most principled move.
Hence it is no surprise that GM Avrukh decided to base his repertoire on it.
White has two main branches here: to play 2.g3, or 2.Nc3 3.g3 or to play 2.Nc3 followed by 3.Nf3.
In this database, GM Avrukh deals with the second option.
The main position arises after 2.Nc3 Nf6 3.Nf3 Nc6, the so-called “Four Knights Variation of the English Opening”
In this position, White tried almost everything.
Boris analyzes 4.g3, 4.e3, 4.d3, 4.d4, 4.a3, 4.d4 in detail.
The first chapter is about the move 4.a3.
This move looks dubious, but it not so easy to deal with it.
For example, Kramnik, Topalov, and Ivanchuk have used it with success.
The main line here starts after 4…d5, but Boris was not impressed with this variation and suggested continuing with the second most popular move – 4…g6.
This is the only variation where he recommends to fianchetto the bishop. It makes perfect sense here because White’s 4.a3 looks like a waste of time if the bishop is on g7.
White has two main setups here: 5.e3 or 5.g3, but we meet them in a similar way. Just Bg7, 0-0 and d7-d5 with an excellent play in both cases.
This chapter deals with 4.d3.
This is not the most challenging line but there is some logic to it.
White wants to play Sicilian with a tempo up.
Black should accept the challenge here and play 4…d5!
The main line arises after the moves 5.cxd5 Nxd5 6.e3 Be7 7.Be2 0-0 8.0-0 Be6.
So, both sides achieved their outcomes. White reached his desired setup and Black developed his pieces actively and has an advantage in the center.
Boris analyzed this Scheveningen setup in depth and proved that Black has at least equal play.
In this Chapter, GM Avrukh covers the move 4.e4.
This is a very tricky move after which White’s set-up resembles the Botvinnik variation with the c4 and e4 pawns.
Black should answer this in the most principled way. 4…Bc5 and now White continues with 5.Nxe5 (otherwise Black is simply better, because of the hole on d4) 5…Nxe5 6.d4 Bb4! 7.dxe5 Nxe4
The theory starts here. Boris analyzed 5 different moves.
The main line continues 8.Qd4 Nxc3 9.bxc3 Be7 10.Qg4 and here Boris suggests 10…Kf8 instead of the main move 10…g6.
Boris analyzed this position very deeply and proves that Black’s position is perfectly playable, and White should be careful to maintain the balance.
In this Chapter, you will learn what to do against 4.d4.
This continuation is quite tricky even though it is not that popular at the very high level.
In this line, Boris reveals some of his novelties and opted for some rare continuations.
For example, in the main line 4…cxd4 5.Nxd4 Bb4 6.Bg5, the author suggests the extremely rare 6…d5!
The chapter is full of new ideas and novelties and Boris proves very convincingly that Black’s position is quite promising.
Chapter 5 and 6
In this and next chapter
GM Avrukh deals with the most serious sideline 4.e3.
This move became very popular nowadays. With a lot of games on top level, it is hard to call it a sideline. It is just a serious alternative to the 4.g3 move.
After 4.e3, the best move for Black is, of course, 4…Bb4!. In this chapter Boris analyses 5.Nd5 and 5.d4
If after 5.d4 Black is equalizing easily by exchanging and playing 0-0 followed by d5, after 5.Nd5, the game becomes really complex.
Black should accept the challenge and play 5…e4 when White has two equally good continuations 6.Nxb4 and 6.Ng1. As you will see in the analyses both moves have their pros and cons, but the evaluations of the arising positions do not change – Black has adequate counterplay in very complex positions where both sides can play for a win. Boris thoroughly explains the ideas for both sides and armed with this knowledge you can play these positions with confidence.
In this chapter, you will find the main line after 4.e3 Bb4 – the move 5.Qc2
Now, 5…e4 is not possible and 6.Nd5 becomes a serious threat.
Even though that in most of the games Black allows that and continues with 5…0-0, Boris didn’t like the position after 6.Nd5. Thus he suggests playing the radical 5…Bxc3.
It looks strange to give up your pair of bishops even without waiting for Nd5 or a3, but this move has a logical explanation. With his fifth move, White loses some time and needs a few more moves to finish the development. In the meantime, Black pushes d5 and tries to create some threats whilst White still needs time to finish the development. The main line goes 6.Qxc3 Qe7 7.a3 d5! 8.d4. Here Black should continue with 8…cxd4 9.Nxd4 Nxd4 10.Qxd4 c5
with enough counterplay for Black.
In Chapters 7-10, the author deals with the main line which arises after 4.g3.
Black has various choices like 4…Bc5, 4…Nd4, 4…d6, 4…g6.
Boris stays loyal to his principle to find new ideas in a less explored territory.
His attention was caught by a new and almost unexplored idea.
The starting position arises after: 4.g3 d5 5.cxd5 Nxd5 6.Bg2. In this position for decades the move 6…Nb6 was played almost automatically. This position is very popular at all levels. The theory considers this line as playable. Both sides have various plans and this position is analyzed quite deeply in different sources. That’s why Boris chose another line, which is fresh and quite ambitious – 6…Bc5.
This move was played in some amateur games, but GM Aleksander Grischuk introduced it at the very high level during the Geneva Grand Prix in July 2017.
The game finished with a nice win for the Russian grandmaster. Since that game, GMs such as Caruana, Karjakin, Wang Hao, Inakriev, and Adams tried this move.
At the end of 2017, we can say that this is the most topical like in the English opening and you can expect hundreds of new games in this line. Of course, Modern Chess will keep you updated about the newest trends in this line, but for now White failed to prove an advantage here.
GM Avrukh’s analyses are quite rich of new moves and ideas and most importantly he manages to explain all important strategical and tactical ideas.
In Chapter 7, Boris shows us that all the tricks like 7.Nxe5 or 7.0-0 0-0 8.Nxe5 are not working for White.
He also analyses 7.0-0 0-0 8.d3 Bb6 9.Na4 which was tried by Eljanov in his game against Grischuk.
The verdict is clear – Black has a very promising position in this line.
In this chapter, Avrukh deals with the line 6…Bc5 7.0-0 0-0 8.d3 Bb6 9.Nxd5 Qxd5 10.b4!?
That is a very interesting move tried in several games. The most famous one was Dubov – Karjakin when the young Russian GM crushed his famous opponent. Karjakin faced this position twice and continued with 10…e4 which according to Avrukh is a good move that probably equalizes but requires some memorization and the variations are sharp. Instead of that Boris suggests quite a natural improvement 10…a5 which occurred in the recent game B.Gelfand – Wang Hao. Here the analyses run really deeply, but Black has good and simple play in all the lines.
In this chapter, you can find the position after 6…Bc5 7.0-0 0-0 8.Nxd5 Qxd5 9.Ng5!?
This interesting move was tried by Levon Aronian. He eventually won the game against Caruana, but later analyzes prove that White ought to be the one who should be careful maintaining the balance here.
In the last Chapter Boris covers the most natural approach for White – 6…Bc5 7.0-0 0-0 8.d3 Bb6 9.Bd2
This move was tried by GM Anand and by the current World Champion under 20 the Norwegian GM Arian Tari.
Now after 9…Bg4 10.Rc1
Boris is not quite satisfied with the move 10…Nc3, which Caruana played against Anand, and suggests not one but two novelties here – 10…Re8N and 10…h6N.
Plenty of analyses are done and armed with them you will be able to surprise even the most prepared opponents.
As always at the end, you can find 20 test positions. Here are 5 of them.
