I've often wondered about 5 f4. I guess Black's choice is to go into a Modern with 5 ...Bg7 or else try 5 ...b5!? (which engines seem to favour). Any thoughts on this? The position seems quite weird and unlike many other Pircs ...
Some thoughts:
(1.e4 d6 2.d4 Nf6 3.Nc3 Nf6 4.Be3 a6 5.f4
b5)
(1.e4 d6 2.d4 Nf6 3.Nc3 Nf6 4.Be3 a6 5.f4
Ng4)
(1.e4 d6 2.d4 Nf6 3.Nc3 Nf6 4.Be3 a6 5.f4
Bg7)
Are the reasonable continuations imo.
1.e4 d6 2.d4 Nf6 3.Nc3 Nf6 4.Be3 a6 5.f4 b5 6.e5 looks quite strong. For example:
6...b46...Ng4 7.Bd2! (not 7.Bc1 mentioned in Chess Developments the Pirc p.160) and black's position does not make sense.
7.Qf3 c67...Ra7 8.Nd1 Ng4 9.e6! looks horrible for black.
8.exf6!? bxc3 9.fxe7 Qxe7 10.bxc3And I don't think this is a position where black has sufficient compensation for the pawn.
1.e4 d6 2.d4 Nf6 3.Nc3 Nf6 4.Be3 a6 5.f4 Ng4Is reasonable but releases the pressure on the e4 pawn.
6.Bc1 Bg7 7.Nf3 b5!?7...0-0 8.Bd3 gives white good coordination.
8.h3And black would like to play the following as others don't really look appealing.
8...Nf6Alas.
9.e5! Nfd79...Ng4 10.Bd3 is also good for white.
10.h4!Is a standard idea that seems to work well.
So for me 5...Bg7 seems best when a plausible line is:
1.e4 d6 2.d4 Nf6 3.Nc3 Nf6 4.Be3 a6 5.f4 Bg7 6.Nf3 b5!?With a complex position.
6...0-0 transposes to a not so good looking sideline of the 6.Be3 Austrian btw.
Have a nice day.
