French Wing Gambit

It goes as 1. e4 e6 2. Nf3 d5 3. e5 c5 4. b4
Anyone has experience with it? I'm interesting in countering it as black. Also probably there is a good alternative for black on the 3d move to avoid it (although c5 is natural move). I imagine that Sicilian wing gambit could transpose into it, so any info about it is welcome as well.

If anybody (preferrably 1600+, unrated or rated game) would like to play it as white against me, please send me a challenge.

I would appreciate in info/ideas/advises.

Thanks,
Igor

PTF gives the line 4 ... cxb4 5. a3 Nc6 6. axb4 Bxb4 7. c3 Be7 8. d4 f6 9. Bd3 fxe5 10. Nxe5

I would prefer 10. fxe5. After Nh6, Bxh6, both castling option does not look safe.

White doesn't have an f-pawn available for capture. Assuming that you meant 10. dxe5, Watson quotes 10 ... Qc7 11. 0-0 Nxe5 12. Nxe5 Qxe5 13. Bb5+ Kf7! -+ Hamed-Garma, Novi Sad 1990.

dxe5 of course. White probably better hold for e pawn with 11.Qe2, but objectively black should be fine. Thanks a lot for the info!
