Another question about the 4 pawns:
I gave it a try in a recent game and was faced with this move order:

1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f4 0-0 6. Nf3 Bg4!? 7. Be2 c5

I intended to play the dxc5 lines against 6...c5 but could find a way to make use of black's early bishop move. So play continued

8. d5 e6 9. 0-0 exd5 10. cxd5

when we were back in the main line.
My question is: Is there any way for white to benefit from the early Bg4?

In addition to the works mentioned here, there's an in-print book in German on the 4PA that is also worth having.  It's named, prosaically, Konigsindische Verteidigung: Vierbauern-Angriff.  It's accessible since it's written in straightforward chess German.

what would you play against QGA?

It looks as though you're adapting my repertoire for White:

I play:

4 Pawns against the KID
Exchange with Nf3 and Rb1 against the Grunfeld
4. f3 against the Nimzo
Zaitsev against the Benko
5. a4 and 6. Ne5 against the Slav
Bf4 systems with 0-0-0 if allowed in the QGD
Staunton with Bg5, d5, Qe2 against the Dutch

It's a nice repetoire. None of the lines are unsound or bad, and they lend quite well to specialization, etc...since they still have amassed theory that's quite sharp. I've scored really, really well with this repertoire.

Regarding the Zaitsev, it's certainly interesting, and very little played, so you stand good chances of surprising people. You can reach some really bizarre positions, most of which are quite un-Benko like.

Good luck, feel free to ask more questions. Quite an interesting thread for me....

I love the 4-pawns, and have played it as my main weapon against the KID for as long as I've been playing 1. d4. I think both "Beating the KID and Benoni" and "The Fearsome Four Pawns Attack" are both great books. The former is written by an expert on the 4P's, and is quite good, with more explanation, but still a lot of theory. Sometimes I prefer to use this book because it's a little easier to follow and learn from. The Fearsome Four Pawns Attack is much denser, thicker, and contains a lot more information. Also, it gives some more aggressive treatments than in Vaisser's book. I'd say both are worth having. A lot of times when I'm preparing a line in the 4P's I use Vaisser's book first to try to understand everything and build the theory up, then I use the Fearsome Four to extend my knowledge and as a reference after I've played the line in question a few times. Get both!
