1.d4 f5 2.g4 hxg4 3.h3 g3! nearly put an end go 2.g4. That is until a shabby pawn sac was discovered. After the standard 4.fxg3 Nf6, there is 5.e4!? . This is probably a TN (Theoretical Novelty)!
5. ... Nxe4 (5. ... d5!?) 6.Bd3
A.) 6. ... Nxg3
Black has gone too far. Sure, he stops Qh5, clips a pawn, and threatens the rook but ...
The knight is lost (7. ... Nxh1 8.Qg6+ and mates).
B.) 6. ... Nf6
This is one interesting way to go. Obviously, there are other 7th moves for white as well.
C.) 6. ... d5
7.Bxe4 dxe4 8.Nc3
As you can see, all these variations lead to interesting untested positions.
All you have to do is keep an open mind and an eye out for a shabby pawn sacrifice, and you are in business.
