I missed this thread the first time around, due to vacation...

Palliser (2007) Fighting the Anti-Sicilians has good coverage of the ...e7-e6 systems mentioned here, in his Grand Prix Attack chapter.
1.e4 c5
A) 2.Nc3
A1) 2...Nc6 3.f4 e6 4.Nf3 d5 5.Bb5 Nge7 with a big branch here.
A2) 2...e6 3.f4 d5 4.Nf3 dxe4 5.Nxe4 Nc6 6.Bb5 Bd7
B) 2.f4
B1) 2...d5 3.exd5 Nf6! 4.Bb5+ Nbd7!? (his marks)
B2) 2...e6 3.Nf3 d5 4.Bb5+ Bd7

One thing I was surprised to learn is in line A1 black is doing well after 6.exd5 Nxd5 7.Ne5 Bd7 8.Bxc6 Bxc6 9.Nxc6 bxc6. (A game he quotes is A.Kosten - S.Cvetkovic, Belgrade 1988.  Smiley ) Palliser thinks black is fine everywhere, but it might be useful for English Opening players to have a look and see if they could be more than fine with reversed colors and an extra tempo.

RE 1.e4 c5 2.Nc3 Nc6 2.g3 g6 4.Bg2 Bg7 5.d3 e6 6.f4 Nge7 7.Nf3 O-O 8.O-O d5
I consider this line to be ideal for black, and always avoided it with Smyslov's 6.Be3.

RE 1.c4 e5 2.Nc3 Nc6 3.e3 f5 4.d4 Nf6 5.Nge2 d6 6.g3 g6 7.Bg2 Bg7 8.O-O O-O 9.Nd5!?
The real question here is, why did white castle? Wouldn't it be better to play 8.b3 O-O 9.Bb2 (maybe even 9.Ba3!?) ... ? White can develop flexibly on the queenside while if black wants to get anything going on the kingside he needs to make a commitment. See e.g. Anand - Kasparov, New York rapid 1994 (http://www.chessgames.com/perl/chessgame?gid=1018557). Kasparov said he was doing well until the mistake 16...d4. It's all very reminiscent of the ...e6/...g6 system against the King's Indian Attack.

Wow, I have not got the Cummings book yet, but I been wanting too. The nc3 lines look interesting. Another book in putting on my list. Wonder what they will give vs c5. The Anglo benoni (lines with d4) was never my thing. I usually played things like a3 going for b4 instead.

Given the unforced character of the line I don't think a detailed discussion will yield useful results. However I'd like to point out - I forgot it thus far - that the variation with colours reversed also scores badly for White: 1.e4 c5 2.Nc3 Nc6 2.g3 g6 4.Bg2 Bg7 5.d3 e6 6.f4 Nge7 7.Nf3 O-O 8.O-O d5. Apparently something weird is going on; all the more reason to look at the Closed Sicilian as well when incorporating this line in your repertoire.


I think there can be many reasons some variations score poorly besides the objective worth of the position.  Sometimes more accuracy is required for a few moves to give a plus or to achieve equality.  Maybe someone will use AlphaZero to play itself thousands of times in these positions to figure this out.  Smiley

No, I don't think so but I've been looking at 9.Nd5!? with the help of the computer and it seems promising to me (so far!).  (Should we continue this discussion in another thread perhaps?)

That's a non-sequitur unless you think that opening books can neglect all bad moves.


I believe authors can neglect lines which are both rare and bad, which I thought I stated clearly enough.

I propose we just agree to disagree here,  this discussion has nothing to do with the Georgiev/Semkov book at this point.

That's a non-sequitur unless you think that opening books can neglect all bad moves. Also you carefully neglect the fact that page 107 has more than enough space left for an extra note. Perhaps you prefer empty space to an IM's take on a natural developing move?

After 1.c4 e5 2.Nc3 Nc6 3.e3 f5 4.d4 Nf6, 5.Nge2 seems like a decent enough move.  Maybe there's no advantage but it's English like in that it keeps a lot of pieces on the board and preserves some tension.

I started to look deeper into this recently and I'd say the reverse is true.  I used to play the 3.Nf4 f5 system as Black and it still seems to hold up well.  In the system with e2/Nge2 I can't find an equalizing line.

why not 5.d5?

Wrong question, so I'm not going to answer it. Better question: which famous opening sees White playing d4-d5, attacking Nc6, while Black needs several moves to prepare ...f5 ?
When you've found the answer you'll recognize that a) not being able to play ...Bb4 is irrelevant and b) that the most important difference is the pawn on d7 iso d6. So 1.c4 e5 2.Nc3 Nc6 3.e3 f5 4.d4 Nf6 5.d5 Ne7 6.d6 cxd6 7.Nb5. White has decent compensation, but again that's not the correct question.


I guess you mean the King's Indian? I'm not sure that I follow the analogy. This is a completely different position. Also, in many KID lines, black would love to exchange the dark-squared bishop.

Instead of your 1.c4 e5 2.Nc3 Nc6 3.e3 f5 4.d4 Nf6 5.d5 Ne7 6.d6 cxd6 7.Nb5, I would rather play 6.Nf3. Now if 6...d6, we have 7.Ng5, with a typical King's Indian Bayonet motif of landing it in e6 and grabbing the good bishop. If 6...Ng6, then 7.h4 leaves the knight looking short on squares, or leaves a gaping hole on g5 in the event of 7...h5.

This line is rare, and I believe it is bad for black. Consequently, I think it's completely fine that it is not given any coverage by Cummings.

The Hansen book has a chapter (actually two) on f5 tries, and he generally argues that d4 is a good try at getting an advantage. As in 1 c4 e5 2Nc3 Nc6 3 Nf3 f5 4 d4 then e4.

that the analogous 5..Bb4 from the colours reversed line is an outright blunder.

After 1.e4 c5 2.Nc3 e6 3.f4 d5 4.Nf3 dxe4 I bet that 5.Bb5 is not exactly the very best move. 5.Nxe4 and 6.Bb5 is only promising if White can cripple Black's pawn structure with Bxc6 (...bxc6 being the only possible answer). So you actually confirm that IM Cummings should have given the English version more attention; it's far from obvious how White can show that the extra tempo is useful, this setup being far from the most ambitious one against the GPA. Lack of space is not an excuse as there is plenty room left on page 107.

The question is if White's chances for an opening advantage are better here than in 3.Nf3 f5 4.d4. I doubt it.
Also compare the Black Tango 1.d4 Nf6 2.c4 Nc6. White's 3.e3 is pretty useless. Finally: have you looked at 1.e4 c5 2.Nc3 e6 3.f4 d5 4.Nf3 and now d4? Why would it be so much less popular than dxe4 ? IM Cummings' "3.e3 saves two tempi" only becomes more superficial.

Now we're at those GPA lines with colours reversed: even a more serious omission in Cummings'book is 1.c4 e5 2.Nc3 f5 3.d4 exd4 4.Qxd4 Nf6, which is superior to 4...Nc6. For instance Peter Svidler realized that as a youngster.

My view that IM Cummings'book, with its many qualities, does need a complement stands only taller.

At the other hand, if you like 1.c4 e5 2.Nc3 Nc6 3.e3 f5 4.d4 Nf6 from White's perspective by all means play it.

Does black really need to play 4...dxe4 here? Why not 4...d4? Some strong correspondence players have gone this way and most often have met 5.Bb5+ as the reply.

Quote:
So he doesn't consider 1.c4 e5 2.Nc3 Nc6 3.e3 f5 4.d4 and now the simple Nf6.


After 4...Nf6, continuing with our analog from the colours reversed, why not 5.d5? Makes even more sense now that the analogous 5..Bb4 from the colours reversed line is an outright blunder.

IM Cummings actually recommends 1.c4 e5 2.Nc3 Nc6 3.e3 because compared to 3.Nf3 f5 4.d4 e4 5.Ng1 he wants to win two tempi. Unfortunately one of several flaws in his book (it's pretty good, but not as good as gillbod seems to suggest above) is he not recognizing that the variation is a joy killer with colours reversed: 1.e4 c5 2.Nc3 e6 3.f4 d5 4.Nf3 dxe4 5.Nxe4. So he doesn't consider 1.c4 e5 2.Nc3 Nc6 3.e3 f5 4.d4 and now the simple Nf6.
So I strongly consider buying Georgiev/Semkov's book as a complement.

Speaking of e3, you can even play it a move earlier.  (Dennis Monokroussos on an article in Informant 135:  "GM Ivan Ivanisevic offers a compact white repertoire in the English built on 1.c4 e5 2.Nc3 Nf6 3.e3. He doesn't promise an advantage, but the positions are fresh and not easy for Black to solve at the board - especially if he doesn't play the Sicilian with White, as many of the positions transpose into reversed Sicilians.")

Wasn't that the basis of David Cumming's book?  I suspect that's the primary reason, at least among amateurs.

It may be a reaction to an explosion of theory in the g3 lines since Marin helped to populize them.


This and perhaps a reaction by those following Tony's book and facing the c6 lines that came out in the dangerous weapons one as an antidote?

Also, could transpositions have anything to do with this?

Chess Stars stuff is generally good, so this is welcome news.

Cummings's book is really good, though, so I'm not sure whether I would pull the trigger on this.

Given that the theory on these lines is not so developed (though surely being developed very quickly given the current popularity!), I wonder what to make of a multi-volume tome. Will the extra space be spent on analysis, or explanation? I would generally favour the latter for these lines.

I recall a different view from Timman some months ago (YB 126).  The article was about this 4. e3 line (which he faced from Korchnoi, Miles and Keene 41 years ago ...), and he wrote something like:  I expect to see more of g3, since Black has been doing so comfortably here.

This sounds interesting. It should be a good complement to David Cummings' Opening Repertoire: The English.

Georgiev/Semkov on English
07/23/18 at 08:36:04
Post Tools
Chess Stars Publishing has announced a new book on the English,
(obviously the first volume in a whole series on 1c4 for White)

The Modern English Volume 1: 1.c4 e5
by Kiril Georgiev and Semko Semkov
expected in September

The book is written by White's standpoint and covers non-g3 set-ups:
1.c4 e5 2.Nc3 Nf6 3.Nc3 Nc6 4.e3 as a main weapon and 4.d3 as an alternative.
Some notable exceptions are 1.c4 e5 2.Nc3 d6 3.g3, although 3.Nf3 and 3.d4 are also analysed.
The book goes beyond a straightforward repertoire, and covers different approaches.
Thus it should serve well players with both colours.


Imo Semkov´s books are always very readable, practical and useful!
