A "terrific" wait-and-see move is 13..g6  Cool ... aiming for a poker-bluff style of play. 14.Re1 Ng4 ; 14.Ne2 Qb6 ; 14.Qd2 Qd6 15.g3 Nh5 ; 14.Rc1 Qb6 ; 14.Qe2 Qd6 ; 14.Qc2 Qb6

I recorded one analyzed line about this game (I am pretty sure that I read it from chess book about French...maybe in NiC Survey #25 about Geller-Zuger,Berne 1988 and Ivanovic-Maksimovic,Banja Vrucica 1991 and Krabec-Krecmer,corr 1990 ; or Svidler-Volkov,Francfort 1999 (Psakhis Nd2) ):

20.Rc1!  (20.Rg5?!) Qxe5 21.Qa4 Bd7 22.Qxd7 Nxd3 23.Rc8+ Rxc8 24.Qxc8+ Kf7  25.Qxb7+ Kf8 26.Qa8+ Kf7 27.Qxa7+ Kg8 28.Qe3 +/-

Interesting, this 14..Ng5 idea seems to score pretty well. On chesstempo.com database 4 games between 2400+, all draws. Obviously not a big enough sample size, but it is still somewhat encouraging. GM Sergei Rublevsky (2700) - Marc Simonet (2270) was drawn. I haven't analyzed the game yet, but the result is rather surprising. 

Mikhail Ulibin (long time french player) played this line against Zoltan Almasi in 2000, Svidler -Volkov was in 1999, 
and Gelashivili - Mchedishvili was from 2001. All games were drawn.

By the way, you shouldn't be afraid of your opponent's theoretical knowledge. If they are higher rated than you, usually they will be trying to get you out of book early (i.e. play a sideline). 


Actually, this often, not always, makes sense, just from a pure statistics point-of-view. An opponent rated lower than you are more likely to have studied fewer lines, and if they have studied something, it is probably main-lines or early deviations. 

Another thing that I have heard, can't remember where, is that you as lower rated should play the mainlines simply because these are based good moves. That way, you will not play bad moves. I guess it won't hurt if you still know the ideas behind the moves, though. Especially when playing against 2200+ players  Grin

Fair enough. Ziegler's DVD was produced in 2006, when 14.g3 was the trendy move. Then again I don't think 14.Qc1 is enough for an edge either, but if someone proves me wrong I might start playing this line again.

How much theory does one need to know to have a real fighting chance against 2200+ players?  


If you are a reasonable player, very little. But of course additional theoretical knowledge is an advantage. Even when I play openings which either have very little theory or very little theory that I know, my theoretical knowledge of other openings help me to find good moves over the board. For instance, I have beaten many players in blitz with a rare variation of the St George, based on an idea in the French Defence (finally got back on topic =P ).

By the way, you shouldn't be afraid of your opponent's theoretical knowledge. If they are higher rated than you, usually they will be trying to get you out of book early (i.e. play a sideline). 

Re bragesjo's analysis on 14.Qc1 (which is more testing than 14.g3 in my opinion), I don't second the recommendation of 14...Qf6. Instead of 19.Nc3, White has a slight edge after both 19.Qc3 and 19.Nc3. White has won five games and drawn ten from the position after 18...dxe4, which is not a good advertisement for Black; better is 14...Ng5.

I should point out that Ziegler mentioned that his 15..Rd8 may have been an inaccuracy. He gave alternatives, which I posted. 

Thanks, for the advice.

11... Qc7 12. g3 O-O 13. Bf4 : I play this line as Black...enough tactics to enjoy it.

13...Ne4 : you have three alternate interesting systems: 13...Qc7 line I chose vs Khamrakulov (and despite my loss I enjoyed to play it and to get nice analysis with my opponent after the game ; maybe Qd6 is more precise, but I wanted to keep Qb6 move later)  ; 13...Qd6 (variation played by Lautier vs Hellers when he won junior championship in 1988..I don't know why it is not so much covered in books) ; 13...Qb6 ("Watson's line" was Neil McDonald's quote in old chesspub updates ; I have work analyse deeper the 14.b3 sublines with 14..Ne4 and 14..Bd7)

14..Qf6/g5: you have 14..Qb6 too

14..Qf6 15.h4 g5 16.hxg5 Nxg5 17.Kg2 is Tzermiadianos's pawn sacrifice

14...g5 is safer for Black...at current time my best line for White is a draw

My post will not add more than MartinC ones: for each line you will choose, you have work to do to build (as Black) new specific plan for handling well the semi-ending position ( I assume Ziegler's Rd8 was one one of them, to keep an advantage with pawn in center to counter White activity ).

Well you've almost 'got' to investigate them anyway, to see if you like the feel of the play or not. 

New moves not so important, the key is that you've investigated/thought about the position. Hopefully some of that will then stick in long term memory Smiley

In terms of what he's going to show in a DVD: its really not practical to show genuinely dense theory in those. Also authors (books too) do have a tendency to try and show secure lines rather than very tactical things which might just get busted. Very sensible of them really.

In this game below IM Ari Ziegler says that after 14..g5 black needs to know ten more moves of theory in several different lines and that much of it is unpublished. Instead recommends 14..Qf6, which is safer but leaves it structurally dificult for black to play for a win.  

Do most 2200+ players analyze their own openings and come up with new ideas or do they follow book reccomendations? 



I know at least three 2200+ players that don't know that much theory. They just play lines they know well, even if they are not considered the very "best". Of course they know the basic plans, but I am surprised they don't know more theory.  

Where did Ziegler say that Black needs more theory (since there is nothing about it in the annotations)? The CB DVD?


Yes, He consistently states that what he is recommending is good enough for equality. There are several positions that arise in the DVD where he says something like: " And here this move is very theoretical. I have analyzed it for hours and I believe it to be a draw, but you must know another ten plus moves of theory in several lines". He basically opts for the quiet solid approach with black. One such position is the one given above where he suggests Black play 14...Qf6 rather than the more theoretical 14...g5.   

I guess it would be more fun if in investigated some of these lines myself and came up with some new moves.

Mostly at least some work - and some certainly a bit independent - but certainly don't overestimate it Smiley For a fighting chance not much. Rather more likely to get in trouble being outplayed if they're stronger than you.

But.... This specific line? Its been theoretical for ages. 

Once white has decided to play 7 Ne2 and not 7 Ngf3 he's almost committed up to move 14. Since this line is so well known and forcing that they'll (almost) certainly have decided what to play then and at least looked at its consequences.

I'd think they're likely to then remember the basic plan(s) they decided on and maybe the odd tactical sign post. What is much less likely - unless of course they've got time to do specific prep for you! - is them remembering a bunch of very precise theory.

What you really need to decide is whether you'd be confident of doing OK in that position if you're playing off half remembered memory. That really depends on the position, how (un)natural the specific moves involved are to you, risk for both players etc.

In this case I've not checked so don't know Smiley Its a bit personal anyhow.

Also, is 14...g5 really better 14..Qf6?  Maybe i should play a different line altogether if playing for a win?
