The sacrifice on e4 in the Paleface Pirc

Yesterday I was crushed to death in a Paleface Pirc. The game was played at fast speed, but still, I was sort of humiliated with my opening. read carefully so you dont end up like this !

Guido De Bouver - Roel Hamblok ( Antwerpen )

White has declared his intentions on the kingside whilst blacks expands on the queenside - a typical idea in the Paleface Pirc.

My next move was too slow : 9.h4. This move is too slow as it allows for 9...h5, but my opponent had a different plan : 9...b4 (diagram)

Oh horror - black is attacking a piece first. Probably an indication that I am not doing so well. But now I missed a simple sacrifice.

10.Nce2 ??? (diagram)

As soon as I released my piece, I saw the combination. 10.Nd1 would have been ok for white.

10...Nxe4 Of course.
11.fxe4 Bxb2 12.Rad1 Bxg4 (diagram)

And with one piece for three pawns, I could safely resign here as my position is hopeless.

Dont fall for this idea - it can happen in other Paleface Pirc positions also.
