I find it hard to feel enthousiasm for this line, as Black should choose a plan with castling queenside after 5.g3 and White should play 5.Nbd2. But I have looked in my database:
1.Nf3 d5 2.d4 Nc6 3.g3 f6 4.c4 e5 5.dxe5 d4 6.exf6 Nxf6 (peculiar move order) 7.Bg2 Bc5 (Bf5 and 8...Qd7) 8.o-o o-o 9.Nbd2 Qe7 (Bf5 10.Bb3 Ne4 11.Nh4!) 10.Nb3 Be6 11.Bf4 Rad8 12.Bxc7 Qxc7 13.Nxc5 Bxc4 14.Rc1 +=/+- Lingnau-Langrock, DEU 2000.

There was a short debate on this Prucha idea in the other Albin's thread, see Daring Defences section. I do not trust it; in my opinion 5.Nbd2! +=/+-.

Last post in that thread:

5.Nbd2 f6 6.exf6 Nxf6 7.a3 Bg4 8.h3 Bh5 9.g4 Bg6 10.Bg2 Be7 11.O-O O-O 12.b4 Ne4! planning ...Bf6>

In this position White has 13.Nxe4 Bxe4 14.b5 Na5 15.Qxd4 as Bf6 16.Qxe4 Bxa1 fails to 17.Ng5!
Also 11.b4 Ne4 12.Bb2 Bf6 13.Nxd4 promises an advantage:
a)13...Nxf2 14.Nxc6 Nxd1 15.Nxd8 Nxb2 16.Ne6.
b)13...Nxd4 14.Nxe4 Nf3+ 15.Bxf3 Bxb2 16.Qxd8+.
Moreover White has 9.b4 Be7 10.Bb2 o-o 11.b5.
As stated before: 5.Nbd2 is so strong because it is flexible.

Does somobody know what is the best white way to play against the IM Prucha black plan in the Albin :
1.d4 d5 2.c4 e5 3.dxe d4 4.Nf3 Nc6 5.g3 f6 6.exf Nxf6 7.Bg2 Bc5 with ... a5, ... Bg4 or Bf5 and 0-0 (not 0-0-0)
The Albin is then played as a real gambit. Black doesn't want to recover his pawn.
Is there a clear good way to handle this on the white side of the Board ?
