Well, that 8...f3! was a very cold shower when I found it, especially since I'd spent a very long time on the supposed main line with black's queen picking up Rh1, finally more or less refuting black's exchange snatching idea, but all in vain due to the presumed inferior 6...Bg4...
5.e5 d5 6.Bb5 Ne4 7.Nf3!? is unclear I think. 6.Be2 is bordering on a forced draw, but there are so many different and similar ideas that it may still be playable in practice as black needs to be rather booked up not to get nervous OTB... And finally, after 6.Bb3 white will be forced to sac an exchange, fritz doesn't approve but it's probably not completely out of the question that white might dig something up here...
If you're really interested in these variations I think you should get the book! But I can give a general direction:
My main recommendation is a new gambit, 5.Nc3 Bb4 6.Ne2!? The Modest Gambit (named thus as it resembles another new gambit, the Humble...)
I also spent a lot of time and energy on 5.Bd5!? The Obstruction Gambit, though here I'm not 100% convinced - one could say this is something of a Muzio in the Bishop's gambit...
Anyway, as this is an open forum and all, I don't want to discuss just my analysis... If there should be any reasonably high level games in these lines it would be more interesting - since with all analysis it's hard to foresee what will prove to be the main line in practice.
One could compare with the exchange snatching idea mentioned above - there's been written a whole lot about it, making it 'the main line' - but as far as I know it has never been played!
But unofficially I wouldn't mind discussing these lines via email, if anyone should find a hole in my analysis or better yet a strong improvement!
