Yes. I can see. London players probably need to book up some more on the Pirc though to be honest. Smiley

Don't speak Russian sadly, even though I have some decent (but fast dimming) understanding of the cyrillic alphabet.

I suppose they are just successful at having other animals voluntarily hand over downed prey in some situations. Wink

All of these analyses look like more than I ever saw in other Pirc book. Have you consulted Nunn's Complete Pirc, Wigus, Marin and all others ¿ If you could challenge all of their assessments, that would be a thing. But a lot of work.

I have the books mentioned but don't really look in them with the view to challenge assessment after assessment. Neither Vigus (limited by his book format - essentially he is rarely trying to fix every single possible crack in the lines he favours) or Nunn (book to old) would feel right to do this against actively in my opinion.

On the other hand. This very 4.Bf4 repertoire goes into a Marin line at one point and some time ago I also mentioned a possible improvement in his 4.Be3 c6 line. Also at some point I mentioned I was displeased with Kornev's 4.Bg5 lines. So there are moments when I think the last word has not been said and things like this happen. Checking for such lines is not really rewarding for me in practical play though. I already score very well against the Pirc/Modern Grin Edit: and with it Grin Grin (even though less well in comparison). At my level possible tests as black are also quite rare and mostly in the already very forcing lines.

Have a nice day.

Having said this I do not like encourage too much. After all, I play Pirc from Black's side  Cheesy

Hi.

Well. I've considered changing my current business plan. This can be said without much of a blink. Grin

Write books is not such an obvious phase 2 for me though mainly because a) I'm a weak player compared to most authors and b) because the only subjects that would make sense would be quite niche Pirc/Modern or some other comparativly non standard opening (non-Nf6 KID comes to mind). This will be a hard sell (and a lot of work).

Instead I have more seriously considered making something in pamphlet form (like a self published PDF). On the repertoire I just proposed for example; although there would have to be time for formatting, editing, improving the text etc. In short a fair bit of work. Maybe someday though.

If ever I publish a repertoire book though... You will now get a very nice comment in the introduction  Grin "Some detractors positively salivated over the possibility of making a quick buck from writing their own repertoire book; aimed, of course, solely at bashing this one. Such egregious capitalism and blatant anti-comradeship amongst chess players brings a tear or two to my eyes. Saddest of all though would have been the communist leaders of a bygone era, who tried and (as can be evidenced) failed in ridding the world of the greedy opportunism on display. Cheesy

Have a nice day.

Edit: Corrected complete misspelling.

Have you thought of writing repertoire book ¿ Your analyses are fairly damned detailed.

Then I could publish a Pirc book for Black against your recommendations.

That last part was joke by the way  Cheesy

Hi.

I really need to go through it before posting, but in the near future I intend to post an analysis file. Then it will be possible to deduce exactly how far off the mark I am in my promotion of 4.Bf4 as a serious try for advantage.

Have a nice day.

4.Bf4 Analysis - Part 6: c6 compactness with early Qa5

1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Bf4 c6
As in 4.Be3 and 4.Bg5 this 4...c6 move can be played in order to reach quite different, yet very interesting variations compared to the immediate Bg7. At first it seemed to me (and certain author GMs who reach this by transposition) like the way for black to play in order to reach something reasonable was:
5.Qd2 Nbd7 6.Nf3 Bg7
Where I analysed the reply 7.Bh6 earlier and thought white ends up with chances to press. That's it then? The way I recommend white to play throughout the 4.Bf4 repertoire is to play Bh6 at the right moment and try to get a favourable forcing of the play against most black attempts. Well... chess appears not so easy. That is because there is at least one line, pointed out by MNb, after 4.Bf4 c6 that doesn't really allow a favourable early Bh6. Checking this line I also think I found another move; which seems very solid for black.
5.Qd2 Qa5 6.Nf3
6.a3!? seems quite decent for those who want an easy life. The idea is to postpone Nf3 for one more move in order to keep maximum flexibility and make Bg4 a non-move for black. I covered some other moves in earlier posts although the main problem I found is that black can play 6...e5. A reasonable couple of lines after that would look like:

6.a3!? e5 7.Be3!
Meek-looking but also the only challenging move. I checked some others when I still had hopes for this to work well for white.
7...Nbd7
7...Bg7 8.dxe5!? dxe5 9.Bc4 O-O 10.Nf3 (+/=) I think looks so harmonius for white that it should be slightly better for him.
8.Nf3 Bg7 9.dxe5!? Nxe5
9...dxe5 10.Bc4 O-O 11.O-O Ng4?! Otherwise white just goes h3 and again appears to have harmony in his position, but lunging rarely helps. 12.Bg5 Re8 13.h3 Ngf6 14.Be3!? (+/ = )
10.Nxe5 dxe5 11.Bc4 O-O 12.O-O-O b5 13.Ba2 Re8 14.Kb1 Qc7 15.f3 Be6 16.g4 (+/ = )
White is more comfortable albeit without having made a serious breach of black's position yet. If he is content with something like this 6.a3 is probably simpler than what I am about to recommend after 6.Nf3.

6...Bg4!?
My attempt at giving black a playable position. Even if it isn't really a sexy move the c8 bishop is not so fundamentally important and exchanging it works towards making black's position easier to play and understand. A nice side-effect is also that kingside attacks are not likely to be very dangerous (immediately at least!) without the soon to be eliminated knight's participation. The downside is the loss of the bishop for knight, which tends to mean black limits the types of positions he can go for strategically. With such a flexible pawn structure  bishops tend to be at least a little bit stronger than knights limiting black somewhat.

6...Bg7
After this white has some kind of positional conondrum to solve. Per formula he would like to play Bh6, but this is unworkable because Nxe4 will happen. If not that he would probably like to develop somehow and start to put pressure on black. How is that development and pressure going to look though? Black will take steps towards equalising the position if given time and just getting pieces out is probably not going to be enough to gain much of an advantage for white. He needs to find near enough optimal spots for his pieces but especially where to put the light squared bishop is not so clear.

I have a move suggestion connected to an idea that I will propose below. It seems decent but is also not the easist way of playing. Still. Checking alternatives convinced me it is not so easy to demonstrate advantage anywhere. Because of this I don't think white should principally be to unwilling to enter into slightly more complex lines. I am talking about the following; where black should have a hard time deviating without doing something very non-standard:
7.Bc4!? b5 8.Bd3 Bg4 9.e5 Nh5 10.exd6 Bxf3 11.gxf3 Nxf4 12.Qxf4 e5! 13.dxe5
Now this could well be just unclear, yet I think white may get chances with the following:
13...O-O 14.Qe4!? b4 15.Nb5! Nd7 16.Nc7 Nc5
16...Nxe5 17.Nxa8 Nxd3+ 18.cxd3 Transposes to 16...Nc5.
16...Bxe5 17.Nxa8 Bxb2 18.O-O Qg5+ 19.Kh1 Bxa1 20.Rxa1 Rxa8 21.Qxc6 Rd8 22.Rd1 (+/ = ) White has an extra pawn for the moment and seems at least marginally better.
17.Qe3 Bxe5
17...b3+ 18.Ke2 Nxd3 19.Nxa8 Nxe5 20.axb3 Qb5+ 21.c4 Nxc4 22.Nc7 Qb8 23.bxc4 Qxb2+ 24.Kf1 Qxa1+ 25.Kg2 Qd4 26.c5 (+/ = ) White is better.
17...Nxd3+ 18.cxd3 Qxe5 19.Qxe5 Bxe5 20.d4 Bxd4 21.Nxa8 Rxa8 22.O-O-O c5 23.Rxd4 cxd4 (+/ - ) White gets a pleasant endgame.
18.Nxa8 Nxd3+ 19.cxd3 Bxb2 20.O-O Rxa8 21.Rae1 Qd5 (+/ = ) (Diagram)
The exchange up side should have at least some advantage; with so many pawn islands exact play is still very important though.

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*

7.e5!? Nh5
Critical. The idea is to stabilise the position with exchanges. Otherwise:

7...Nd5 8.Nxd5 Qxd2+ 9.Nxd2 cxd5 10.exd6 exd6 11.f3 Be6 12.Kf2 (+/ = ) to (+/ - ) White is definitely more comfortable.
7...dxe5 8.Nxe5 Be6 9.Bc4 Bxc4 10.Nxc4 Qa6 11.Qe2 Bg7 12.Nd6+ Kf8 13.Qxa6 bxa6 14.Nde4!? Nd5 15.Be5!? Nd7 16.Bxg7+ Kxg7 17.O-O-O (+/ - ) White just has a decent plus.
7...Bxf3?! 8.exf6 Bg4 9.fxe7 Bxe7 10.d5!? (+/ - ) White has a positional advantage.

8.exd6 Bxf3 9.gxf3 Nxf4 10.Qxf4 e6 11.O-O-O Qf5 (Diagram)

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*
This is not at all easy to crack but we'll try. There is another line as well however:

11...Nd7!? 12.Kb1 Qf5 13.Qg3 O-O-O!
Playing to capture d6 at some point and clarify the position a bit.
14.Ne4!? Nf6 15.Bd3 Nh5 16.Qe5 Qxe5
16...Bg7 17.Qc5 Qxc5 18.dxc5 (+/ = ) This may not be quite as bad that one could assume for black but white is better.
17.dxe5 Bg7 18.Rhe1 Bxe5 19.Ng5 Rd7 20.Rxe5 f6 21.Bc4 fxe5 22.Bxe6 Rf8 23.Nxh7 Rxf3 24.Ng5 Rf8 25.c4 b6 26.Rd3 (+/ = ) White has initiative.

12.Qg3 Bh6+ 13.Kb1 Bf4 14.Qh4 g5

14...Bxd6 15.d5!
Seems complicated but probably better for white. See analysis file.

15.Qg4 Qxg4 16.fxg4 h5! 17.gxh5 Rxh5 (Diagram)
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*
Proving something here seems hard. I will suggest just playing to gain space. Conceivably some deep analysis might yield a better plan somewhere but black is essentially not cracking in the short term.
18.Ne4 Nd7 19.c4
19.Be2 Rh6 20.h4 gxh4 21.Rdg1 f5 22.Rg8+ Nf8 23.Bh5+ Rxh5 24.Nf6+ Kf7 25.Nxh5 Kxg8 26.Nxf4 Rd8 27.c3 Rxd6 28.Rxh4 (=) to (+/ = ) Black should survive this.
19...O-O-O 20.c5 Rdh8 21.Rg1!?
It seems like white has to resort to something slow like this. The significant downside being that the h-pawn disappears.
21...Rxh2 22.b4 (∞) to (+/ = ) (Diagram)
This seems closer to unclear compared to a position where white has advantage. White has some positional factors to work with though and if anybody is better it is him.

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *

Enjoy.

Unless Black wants to transpose to other Argentian and 150-Attack stuff 4...c6 and 5...Qa5 is the answer.

It seems like what one would like to play when faced with 4.Bf4 at least.

Decent ideas are nice if they are relevant but all the while looking at this I kept wondering if black can not sidestep it entirely. It struck me earlier that what if black just plays the very straightforward:
1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Bf4 c6 5.Qd2 Qa5 6.Nf3 Bg4!?
I could not find an immediate reply. Black just goes Bxf3 against many moves and if given time he will just play the natural Nbd7+e5 when white would be hard pressed to prove he has a good version of that structure (black after all has not played any especially weird moves). I got as far as checking a bunch of moves, which in most cases all look slow, plus concluding that:
7.e5
Was not good enough because of...
7...Nh5!
Now this just seems to work out fine for black.
8.exd6 Bxf3 9.gxf3 Nxf4 10.Qxf4 e6 (=)
And how to break this? Beats me.

Maybe just giving this as equal was a bit hasty. I don't exactly like doubling white's pawns like this, although probably one can eventually find some kind of an edge. I think I will recommend it for lack of attractive alternatives. So the key proposed lines in a soon to come post would then be:
1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Bf4 c6 5.Qd2 Qa5 6.Nf3 Bg7 7.Bc4!?
+
1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Bf4 c6 5.Qd2 Qa5 6.Nf3 Bg4!? 7.e5 Nh5 8.exd6 Bxf3 9.gxf3 Nxf4 10.Qxf4 e6

Not exactly easy stuff but it will at least lead to interesting games.

Have a nice day.

This line (4...c6 5.Qd2 Qa5) annoys me so much that i"ll probably prefer 4.Be3 or even 4.f3. Though probably not for the first time I took a short look at 4.Bf4 c6 5.Qd2 Qa5 6.O-O-O Bg7 7.Bh6 Bxh6 8.Qxh6 but Black will just be happy to have avoided 4.Bf4 Bg7 5.Qd2 c6 6.Bh6 Bxh6 7.Qxh6 Qa5 8.Bd3.
Unless Black wants to transpose to other Argentian and 150-Attack stuff 4...c6 and 5...Qa5 is the answer.

Hi.

I got some time off because of easter and looked a bit more at 4.Bf4 c6. The positions are sometimes quite interesting. With seemingly natural moves doing not a whole lot in black's 5...Qa5 continuation I got stuck quite a bit. The main problem at first seemed like black's natural 6.Nf3 Bg7 reply. It looked fairly hard to tackle actually. Then I came up with the following line, which I think works even if it's a bit complicated:

1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Bf4 c6 5.Qd2 Qa5 6.Nf3 Bg7 7.Bc4!? (Diagram)

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*
The reasoning is that white's pieces are almost absurdly naturally placed. If black just goes Nbd7 and e5 it seems especially nice to have the bishop on the a2-g8 diagonal. In fact I more or less think white should have no problems finding a small positional advantage against such means of play. Instead what I felt more troublesome was the following:

7...b5 8.Bd3 Bg4
A very important move. Black, starting with his b5, plays to inconvenience white early. At first I think this was good enough for some kind of unclear play after:
9.e5!? Nh5 10.exd6 Bxf3 11.gxf3 Nxf4 12.Qxf4 e5! (Diagram)

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*
On further inspection however; I would definitely take white in the following continuation:

13.dxe5 0-0 14.Qe4!? b4 15.Nb5! Nd7 16.Nc7 Nxe5 (and another diagram...)

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*
The position is still sort of unclear and the lines (they tend to multiply...) continue but I feel white's king will be safe on g1 or f1 and he should be able to play to make his material advantage count. I wouldn't hesitate recommending this at all; unless there is something clever for black that I've missed. When this continuation appeared to me I was therefore quite pleased.

Decent ideas are nice if they are relevant but all the while looking at this I kept wondering if black can not sidestep it entirely. It struck me earlier that what if black just plays the very straightforward:
1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Bf4 c6 5.Qd2 Qa5 6.Nf3 Bg4!?
I could not find an immediate reply. Black just goes Bxf3 against many moves and if given time he will just play the natural Nbd7+e5 when white would be hard pressed to prove he has a good version of that structure (black after all has not played any especially weird moves). I got as far as checking a bunch of moves, which in most cases all look slow, plus concluding that:
7.e5
Was not good enough because of...
7...Nh5!
Now this just seems to work out fine for black.
8.exd6 Bxf3 9.gxf3 Nxf4 10.Qxf4 e6 (=)
And how to break this? Beats me.

For whatever reason I also looked at white just playing useful moves but it didn't look convincing:
1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Bf4 c6 5.Qd2 Qa5 6.Nf3 Bg4!? 7.a3 Nbd7 8.0-0-0 e5 9.Be3
This is a downside to white's whole piece arrangement. If black gets in e5 white will lose a tempo.
9...Bg7
And when that happens I don't see why black can't just start playing natural moves, not really afraid of any possible white initiative since it would be started with black having been gifted an extra tempo.
10.Be2 0-0
If white is to gain advantage here it will be because of good middlegame play.

So anyone have any ideas against 6...Bg4? Otherwise I am seriously tempted to just recommend 6.a3 even if it feels wrong somehow to not go for 6.Nf3 after black plays something non-obvious (at least over Bg7 or Nbd7) like 5...Qa5. I think this is enough for some kind of minimal positional advantage but nothing that will punish black.

Have a nice day.

Hi.

I have been meaning to post something more here but have regretfully not had much time to do analysis. Am doing a lot more time sink heavy tasks at work right now compared to a few months ago and this is the main reason for not working on chess.

Will try to do one final post covering 4.Bf4 fourth move alternatives in the near future I guess.

When it comes to this continuaton after 4...c6:
1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Bf4 c6 5.Qd2 Qa5 6.Nf3 Bg7(!)
I think it gives black a playable game without much effort. White can apply pressure but black seems generally flexible. Plausibly white can find some kind of advantage by just playing natural moves but how is not clear to me. I tried a lot of continuations but often it seems like white does not put enough pressure. Once black gets to make his most natural moves (Bg7, Nbd7, 0-0 and usually e5) his position makes a lot more sense compared to a few moves earlier.

If this line props up I would probably forego 6.Nf3 and try 6.a3 instead. The main upside being white can then try to not include Nf3. For example:
1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Bf4 c6 5.Qd2 Qa5 6.a3 Bg7
6...Nbd7 7.Nf3
Now this goes into some lines I covered earlier. Taking away the option of Bg4 is a bit inflexible from black.
7...Bg7
7...e5 8.Bh6 Bxh6 9.Qxh6 exd4 10.Nxd4 Qh5 11.Qd2!? O-O 12.Be2 Qe5 13.f3 (+/ = ) White is at least a little bit more comfortable.
7...b5?! 8.e5 Nh5 9.Be3 dxe5 10.dxe5 Ng7 11.Nd4 Bb7 12.O-O-O O-O-O 13.f4 (+/ - ) Black's position doesn't really make that much sense.
8.Be2 c5
8...e5 9.Bh6 O-O 10.Bxg7!? Kxg7 11.O-O-O (+/ = ) White is very comfortable.
8...O-O 9.Bh6 b5 10.Bxg7!? Kxg7 11.e5 dxe5 12.dxe5 Nxe5 13.Nxe5 b4 14.Nxc6 bxc3 15.Nxa5 cxd2+ 16.Kxd2 (+/ - ) This should be very nice for white with some technique.
9.Be3 Qc7 10.dxc5 Nxc5 11.e5 Nfe4 12.Nxe4 Nxe4 13.Qb4 f5 14.exf6 Nxf6 15.Qb3 d5 16.O-O (+/ = ) to (+/ - ) White looks to have the clear better of it in this IQP position.
7.h4!? b5 8.Rd1!? Nbd7 9.Be2
I'm not sure white is really better but there are dynamics waiting to play out in the position. Supposedly white should have some kind of pull; in the short term at least.

Have a nice day.

Hi.

Wow. The forum is back.

If nothing else this means we can have long discussions about the Pirc again.

6...Bg7 is worth taking a look. Most interesting is probably 7.O-O-O and while b5? is refuted by 8.e5 Black may try Nbd7, Bg4 and O-O.
It's a bit weird that there are only two games with 7...Nbd7 8.h3 and both saw two strong players blundering with b5?

6...Bg7 appears very relevant. I was focused on Nbd7+e5 plans and missed it of course but on the face of it I think it's a second major way to handle the 4...c6 move order.

White can not, obvously at least, make his main ideas of Bh6, e5 or h4 work well. Some reasonable couple of moves seems in order and then perhaps something active but black should have decent development. I am not sure if there is something very clever for white but your 7.0-0-0 is up there as one of the moves that looks critical.

Have a nice day.

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.

Hi.

Maybe a bits late to ask. But are you trying to make a White repertoire for 4. Af4, or
various Black repertoires against it ¿ Or both ¿  Cheesy

A white one. If in the process there would be some half-decent black line that got figured out then that's also good.

Good people who both read and recollect will note that only black's fourth move alternatives are not yet looked at. Was hoping to find something comfortable for black up to this point, basically making a dent in my own repertoire, although I haven't really managed.

There is yet another option: 6...b4 7.exf6 bxc3 8.Qxc3 and it's exactly here that Bf4 is better placed than Be3.

It is an option but looks bleak for black. In large part because this well placed bishop.

Have a nice day.

The alternative is to swap queens but this does not really equalise.
