So lately I've been looking at something to play against the bayonet and came across this sideline and I started to do some analysis unfortunately the position is very difficult and I think this is a useful point of discussion.  The line I'm speaking of is after 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 0-0 6. Be2 e5 7. 0-0 Nc6 8. d5 Ne7 9. b4 Nh5 10. Re1 f5 11. Ng5 Nf4!? (the main point of my analysis) 12. Bf4 ef 13. Rc1 Bf6 14. Ne6 Be6 15. de Bc3 16. Rc3 fe 17. Bg4!     I believe this is white's only try for an advantage, however this may be fine.  For the record, I've analyzed h5 Bh5 with the help of my good friend Fritz and while it is not losing for white it provides no advantage after 17... h5 18. Bh5 gh 19. Qh5 Qe8 20. Qg5 Qg6 21. Qe7 Rae8 22. Qd7 and so on, this position should be at least equal for black.  However back to the position after Bg4 I would like to have time to play Rf6, Qf8-g7, and Rah8  along with some kind of a5(b5 responds by white) and b6, but of course there are a variety of plans worth exploring in this position.  Unfortunately in most of the lines I've looked at over the board white has a timely Qd4 to really screw things up.  I'm curious if anybody else has explored this position or if people would like to do some serious analysis on this board.  Thanks
