While preparing this line for my black repertoire, I found a very promising plan for white. 
Looks like a difficult task for black to defend this position imo.

What I was thinking during the game: 
I am just letting this guy get away with all those positionally dubious moves because I can't put him under any pressure, playing the French Defence. I mean, I would probably have defeated him in another defence I had studied (and played) before. This was the price I paid as a French-newcomer.

As for my ..Nb7: I saw that c4 is the right place, but wanted to force ..c5, possibly before White's a5 move

Thanks for the other two replies (and sample games), too.

Just to encourage you cf attacks without light squared bishops, look at these two rather imperfect games of mine. Especially the nasty blunder to lose one.....

But they might help show how much punishment blacks position can actually take while staying alive. Think the one I lost more useful mind, as thats white launching a logical enough attack but just getting himself mated.
(yes the main game was a bit scary to play Smiley)

Na5 and c7-c5-c4-cxd3 is a (time consuming) idea. You get c4 for your pieces.

(Position after 14.Bxf4)

Black's position already looks very pleasant. In particular, that c4-square just begs for the black knight.

Some observations of mine:

1.) You said you were very afraid of White's space advantage. Why? What is White going to do with it? There have been many exchanges and your remaining pieces have lots of room to operate.

2.) Maybe a matter of taste, but I prefer 14...Na5 to your 14...0-0. It is not entirely clear to me where Black's king should go just yet. Maybe I am wrong, but with no white knight to challenge a black knight on c4, White's attack on the queenside should not be especially frightening. And of course, Black can still play ...0-0 later if he so wishes.

(Position after 15.Bc1)

It would not have occured to me to play 15...f5. MartinC is right...you were way too worried about your king's safety. There aren't any white pieces over there!  Smiley  15...Na5 and opening the c-file was the way forward. Your computer gives then 16.Rd1 Rac8 17.h4 and now I disagree with its suggestion of 17...f6. Black should play 17...c5 with a pleasant game.

(Position after 18.Bb4)

MartinC was right again...18...Nb7 is a bad idea. Your sense of danger should have gone off that this square is not where a knight wants to be. That knight wants to be on c4 where it will laugh at White's bad bishop for the rest of the game.

Your first 14 moves were very well-played. Now you just need a little more experience in the resulting middlegames.  Smiley

Interesting Smiley Terribly harmless approach from white of course. Whether black can win - especially after that horrible looking f4 - not sure but should be able to torture him a bit. 

Not a good idea to exile knight to b7 then swap it for that bishop Smiley (with that many pieces off that is - if there's attacks and stuff it can turn out lethal.).

One thing I would say is that you're seemingly a bit paranoid about your king safety. Understandable of course. The thing is that, especially with white squared bishops off!, black can defend some awfully scary looking attacks in these lines. A knight on f5 works wonders.

Worth studying say a bit of the 7 .. o-o Winaver theory to get an idea of how much leeway there actually is.

Inspired by Moskalenkos book (Great work! I need to buy "The flexible french! soon) I also tried this line once so far in a rated game. I got a winning position before some comedy took place. A good variation especially vs. opponents who are not that well prepared.

Regarding my game, if I could do it over again, I would play 17...0-0. White is hardly threatening to take 18.dxc5 since 18...Rfc8 gets the c5-pawn back and the c3-pawn is really weak.

After 17...0-0, probably Black tries to win the b-file with a rook to b8 and maybe plays moves like ...c4 (or ...cxd4 if it's timed well), ...Qa4, etc. Go after those weak white pawns. Black should definitely play on the queenside because most of White's pieces are on the kingside (and not doing anything effective over there, either!).

Thanks for the replies, I have played through all (3+2=) 5 sample games.

I had been reluctant to place a knight to e7 when it could be captured by White's bad bishop (from g5/a3).

One more dilemma: when taking on d3 and White recaptures  with the pawn rather than the queen...  How does it affect the Black plans? (no blokade with ..Na5-c4/..Qc4 available)
Yes, in the last game Seth_Xoma played ..c7-c5 and on d3-d4 took on d4 immediately which allowed the opponent to activate the f3N and attack the strong blockading f5N. 
What other plan should he have adopted?

I have experimented with this line playing both sides. Here are a couple of my online blitz games which reveal some typical ideas and plans. These games are by no means perfect.

Black's system focuses on main strategical idea: to exchange light square bishops.

Why ? ... well, another idea in Winawer is to hinder bishop pair activity (because of the choice of Winawer: to trade an active bishop pair for a pawn structure). 

Pawn play (Kmoch-like explanation style): usually this can be done by reaching some Benoni closed center with f5 or c5. After f5, then White has choice to open kingside wing early with exf6 or do it later with a g4 pawn push. The c5 pawn push is good too to attack center pawn chain or to close all center with a c4 push.

Dream of exchanging light square bishops...can it be real ? Yes, but it takes time..and that's why White usually plays on the kingside, to win something there. For example: if we think about Petrosian's line: 4..Qd7 5.a3 Bxc3+ (Petrosian idea was Bf8...and you have not the Winawer trade as given before: bishop pair vs pawn structure) 6.bxc3 b6 (6...Ne7 7.Qg4 Ng6 - very bad idea is to play Winawer with tempi less: 7..oo 8.Bd3 7.Qg4 f5 8.exf6 Rxf6 9.Bg5 - 8.Bd3 and attack for White is sooo easy, playing normal moves for a wing attack if 8...oo and if 8...c5 9.h4 c4 10.h5 Ne7 11.Be2 +-) 7.Qg4 f5 8.Qg3 Ba6 9.Bxa6 Nxa6 10.Nh3 Nb8 11.Nf4 +/- now knight has reached one excellent square and pressure is on weaknesses e6 and g7 pawns.

Comeback to system after 4...Ne7 5.a3 Bxc3+ 6.bxc3.

Most aggressive is now: 7.Qg4 where Black has no time, and need to play 7..Ng6 (7...Nf5 8.Bd3 and too late for Ba6 now because of Bxf5 ; 7...oo? 8.Bg5 Qd7 9.Bd3 ; 7... Kf8 (Euwe's idea as given by Suetin) 8.Nf3 Ba6 9.Bd3!? Bxd3 10.cxd3 c5 11.dxc5 bxc5 12.oo and now 12...Nbc6 13.Rb1 and 12...Nd7 13.Bg5 (Khalifman)) 

Line to follow is now 8.h4 with focus on hindering Black not to long castle. One good book about it, is Shirov's Fire on Board 2.

8...h5 9.Qd1 (9.Qg3 Ba6 10.Bxa6 Nxa6 11.Qd3 Nb8 12.Bg5 Qd7 is the common position where Black had no time to play Qa4 and long castle....and now 13.Ne2 Nc6! is right plan for Black: blockade with pieces on light color squares Petrushin-Vaisser,Volgodonsk 1983 ... if 13...c5 then White has plan with 14.f4 and an attack on f5 square with help of Ng3 and oo) Qd7 10.Bg5  (better than 10.Bd3 or Be2 where Black has Ba6) Ba6 11.Bxa6 Nxa6 12.a4 (Dom) (12.Qd3 Qa4 and now Black has his counterplay on c file with a later c5-Rc8 and sometimes Nc7 to cover e6 after f4-f5-exf5 moves ; 12.Ne2 Qa4 13.Rh3 c5 or 13...Qc4 Balcerak-Lalic, 2006 ) c5 13.Qd3 Nb8 14.Ne2 transposes to Masisch-Westerinen,Senior Men world championship vallee d'Aoste 2006

***

Now some answers to questions:

"When exactly to redeploy the a6N (after Bxa6) via b8...? " 

Later is better, usually when you are forced to play this move...you need to have in your middlegame plan, safety of king as one main goal..and usually you cannot put it on kingside (because White attacks there) and not safe on center when center is not closed, then long castle is quickest way...that's why you see Bg5 often as a White move.

"When to move it forth to c6 (which is preceded or not by ..c5) and then to a5 ?"

Previous answer and analysis above give a clue: using knight to keep a blockade on light squares takes time, usually knight is well placed on a6 (where he has choice between Nb8 and Nc7)...whereas blockading with queen is  easier with Qc7-Qa4/Qc6-Qc4. My answer is: usually your opponent will not let you do it, better to have two 
ideas (use queen and use knight) than only one.

"When is the right moment to move the a8R (to c8)?"

It's part of the "what about my king's safety ?" question. White will have soon an attack on f and g files, can your king stay safely long time on e8 or f8 squares ? If king safety is not a problem, for example reaching a semi-ending usausally by trading queens, then c file is famously known (cf French pawn structures) as an excellent file for Black: for attacked squares and pawns...then the "moment" is "near the ending" or "not so far from queens removal off the board"

"When to castle long and when to short...?"

I prefer to castle "quickly"...   Smiley   ... If White plays regular sleepy moves as Nf3-Bd3-oo then after Ba6 and a bishops trade, I believe kingside catsling will be available...otherwise, you will to have to engineer long castle or maybe a "manual" castle (with Kd7).

"When is the queen shortie to a4 (via d7) sensible...? When to play for the exchange of it by ..Qd8-c8-a6 ?"

Those who have the "queen blues" will say...quite early (queen is a wonderful blockading piece)...but I will say sometimes queen is useful to protect f7 and g7 pawns..and help a manual castle.

"When is it correct to play for ..f6?"

System b6 is special, and undermining pawn center with f6 is clearly unavailable in many lines.


Don't be shy, you can post your games.. Wink

Not sure if this is a terribly easy line to play. Lots of very subtle manouvering needed, and I suspect not many outright rules. 

cf pressure on whites position - well you're not really aiming for that. You're taking out one of his main attacking pieces and long term after endings and stuff.

Lots of studying of games I guess. Although say Petrosian's might leave you even more confused Smiley

It arises after the moves
1. e4 e6 2. d4 d5 3. Nc3 Bb4 4. e5 Ne7 5. a3 Bxc3+ 6. bxc3 b6 *

This is a closed handling of the Winawer, where ..c5 is delayed.
The line is covered in Wonderful Winawer, where the author cites a CBM article on the subject (which I have not studied yet) and even offers improvements on it.
These six pairs of moves are also mentioned in the repertoire book by Vituigov and Flexible French by Moskalenko. 

I am new to the Winawer (after a break of 14 years) and have started to employ this closed line as Black, but only in blitz games for the time being. (31 games up to now, mostly against not too strong opposition, when even 7.Nf3/Bd3 occurred besides the most frequent 7.Qg4 Ng6 8.h4 h5 9.Qg3/Qd1.)

My problem is that I don't fully understand the position.
For example:
When exactly to redeploy the a6N (after Bxa6) via b8...? When to move it forth to c6 (which is preceded or not by ..c5) and then to a5 ? 
When is the right moment to move the a8R (to c8)?
When to castle long and when to short...?
When is the queen shortie to a4 (via d7) sensible...? When to play for the exchange of it by ..Qd8-c8-a6 ?
When is it correct to play for ..f6?

It is not so obvious how to exert pressure on White's position, which may be a cause of my uncertainty. 
So, I need some verbal explanation. Is there any?

P.S.: Maybe I could even show the games, although I am reluctant because they are poorly played.
