[quote]6. ...Bg4 is the mainline, which might be OK for Black, but I did dabble with 6. ...Nbd7, leaving the Bish on c8.
[/quote]
I'm instinctively more attracted to 6 ...ed 7 Nd4 g6, just 'cos it seems a bit more active. Is there a reason why this should be worse than 6 ...Bg4? Toppy's 10 ...Bg4 (from Sion Castro--Azmaiparashvili) looks interesting -- maybe Black can get in ...b5/... b4?

Hmm, sadly not. It just seems Black is trying to hold on and equalise here. 6. ...Bg4 is the mainline, which might be OK for Black, but I did dabble with 6. ...Nbd7, leaving the Bish on c8.

My Pirc philosophy is meet f4 with c5, Nf3 with Nc6 and f3 with c6. Having played c6 on move 3 rather shows your hand, but it's not the end of the world.

I've dabbled with the Czech, but not played it for a couple of years now. 

I don't think the Czech is busted. Even the line I posted earlier on this thread might be ok for Black ...

If 4. ...Bg4 concerns you, then there is 4. ...g6 and go into a Pirc. You're commited to c6, but then f3 and f4 systems have been avoided.

As for books, Carpathian Warrior Book 1 covers it too, if your eyes can bear the cover  Shocked

I learnt it from Soltis's play 1...d6 book, and finding all the errors in that book (watch out for your Queen getting trapped!) was part of the fun of exploring this line.

I remember a game between gms godena and lazic from some 5 years ago where godena (which is generally amazingly prepared) played 4.Nf3, chased the g4 bishop with h3-g4 played Qe2 and blew the other guy off the bord. Not sure where lazic went wrong though. btw the game quite impressed me and i have tried this setup as white with good success. in italy FM de santis published a book on the czech (calling it the crocodile defence!) where he suggested that this system is one of the most dangerous but i have never really studied it in depth...

[quote author=nmga link=1063396315/15#28 date=1215432422]There's quite a lot on the line Toppy cites in Yrjola & Tella's Explosive Black Repertoire book (pp. 131-8), tho' I've no idea how up to date it is. They seem to conclude Black's more or less OK, but implicitly acknowledge there's a lot of murk/unexplored territory ...[/quote]

The real problem for Black is in the note a) 11. d5!? and 15. Nde4 ( p. 135)

You can find 15. Cde4 in the game Cebalo-Halser Graz 1994 1-0 (33)

Please someone give me the names of books on the Czech System.


This system is also known as the Pribyl Indian and there is a small book devoted to it by GM Jansa and IM Pribyl called How To Play The Pirc - A New System For Black!

I myself played this system several years ago and if studied in conjunction with the Philidor Defence-Hanham variation and the Pirc, then the Czech system could prove to be quite a useful weapon in ones arsenal.

Indeed the 4.f4 lines are critical, but many Whites do not fully grasp all the subtleties required to fight for an edge, and without that knowledge White can get a bad game easily and quickly. Even if White has an excellent working knowledge of the 4.f4 lines, a well prepared Black player still has many resources and even some of the lines given in OFWATA are unconvincing for White, for example in Sion Castro vs Zurab Azmaiparashvili 1996 10...Bg4!? is an interesting unmentioned alternative to the ones given in OFWATA.

I no longer play the Pribyl Indian as black, but for sure it still remains a viable defence with considerable surprise value and it is incredible how very often even strong OTB players haven't the slightest clue how to fight for advantage against it as a quick search on ICC will confirm. 

Simple developing moves get White zilch in this system and the 4.f4 lines require considerable theoretical Knowledge. Attempts by White to steer the game towards quieter Pirc channels with moves such as 4.h3 or 4.a4 allow Black to tranpose to the Philidor Defence - improved hanham variation where the aforementioned moves could prove a bit premature.

Considering most of what I wrote so far, some of you maybe wondering why I abandoned this defence, well part of the reason lies in the following variation: 

1.e4 d6 2.d4 Nf6 3.Nc3 c6 4.Nf3 Bg4 [The key idea of the Pribyl in the quiet lines is to get an improved french position with tha bad bishop outside the Black pawn chain] 5.h3 Bh5 6.g4 Bg6 7.Qe2! e6 8.h4! [This is the most dangerous move for Black to face, the alternative is 8.Bg5 and was used successfully by Ian Rogers in a game that should have won the Brilliancy prize at one of the Olympiads, I forget which, but somehow Kasparov managed to convince the judges that one of his games better constituted the definition of a modern day brilliancy.] 8...h5 9.g5 Nfd7 10.Bh3and I much prefer White in this position.      

The other part of my reason for abandoning this defence is safely stored in my chessbase files.  Wink

What is White's best move after 1.e4 d6 2.d4 Nf6 3.Nc3 c6 4.f4 Qa5 5.Bd3 e5 6.Nf3 Bg4 7.Be3 Nbd7 8.0-0 Be7?
What is wrong with 9.h3? How should Black answer it?
(I have started to play the Czech System as Black. I need help and study material.)
It occurred in one of my web-based correspondence game and I played 9..Bxf3 10.Qxf3 0-0. Should I have played 9..Bh5 instead?

I have played the Czech both OTB and in correspondance and had great fun with it not loosing OTB and only once in correspondance. 

I want to ask about the following line which I think is critical:

1. e4 d6 2. d4 Sf6 3. Sc3 c6 4 f4. Da5 5. Ld3 e5 6. Sf3 Lg4 7. Le3 Sbd7 8. 0-0 Le7 9. De1!

Most games have instead had h3 flicked in and I think black is fine with this. Without h3 black is struggling (IMHO) and our game continued

9..Lf3: 10. Tf3: Sg4 11. Ld2 Db6 12. Se2! ed: 13. La5 Db2 14. Tb1 Da2: 15. Sd4: 0-0 (TN)


However, I feel that black is now busted. 15..Lh4 fails as does Lf6 albeit entertainingly! I think black has to chop on f3 and try and play on the dark squares.

What do you think? 

I struggled on to loose in 30 moves.

It seems true that this is the critical test of black's system but I really think black has enough play here and there are a lot of interesting positions that arise after 6.Qf3 d5 7.Bd3 Na6!
If white now plays 8.Bxe4 dxe4 9.Qxe4 g6! is very strong planning Bf5 and Nb4 gaining light square control and an severely pressuring the c2 square.


White can play Qe2, O-O and g4 with compensation for the exchange. Interesting, but with ...

Quote:

White then may play 8.Nge2 Nb4 and again 9.Bxe4 dxe4 10.Qxe4 is a mistake this time due to the surprising ...f5! 11.exf6 Bf5 when I would love to play this position as black
so White be best to continue wih 9.0-0 Nxd3 10.cxd3 Nxc3 11.bxc3 g6 12.a4 h5 which it seems that white has a nice space advantage but i dont think black's position is unplayable here.  What do you guys think.  Any instructive games in this variation?

thanks


9. f5! and coming down fast along the f file, Black could be in trouble.

How about 6 Qf3 f5 !?

There is certainly nothing wrong with 4.a4,  but if Black then changes plan and goes for a Pirc with 4...g6, White cannot go for the sharpest lines as in the Austrian Attack and the lines with Be3 and Bg5, White will very rarely meet ...c7-c6 with a2-a4.
