What's the benefit to having the Bishop on g1 rather than f2?


The weird thing is that it seems to block the first rank, but it is guarded there. On f2, it will either hang after castling by White, or can be captured with check. Totally unintuitive, as I mentioned, at first sight to place it on g1. I would probably not consider it. But Stockfish of course does!

However, I have found yet another variation, which is 8...a6 9 Bxc6 bxc6 10 dxc5 Kf7 (transposition to Avrukh's lines). Now White plays 11 Be3 and after the recommended 11...Nf5, White has 12 Bg1 (Avrukh only gives Bf2), which seems a bit counterintuitive, but I can't find a route to equality for Black after this move.

Maybe 8...a6, and only after 9 Bxc6 bxc6 10 dxc5 play 10...Kf7. This way we at least avoid the dxc5/Ba4 stuff.


That is true. It seems like White may not have many meaningful deviations to choose from, except maybe 11. Bd2 (given at Let's Check as main variation). However, it doesn't really seem scary for Black.

Ahh, I see. Yeah, at a cursory glance with a computer that does look quite strong - 11...d4 looks near-suicidal and so probably best is to bail into a worse ending with 11...Nxe3 and 12...Qe7


Yes, this looks like a totally different thing. But if this is the critical line, is there any chance to save the variation at all for Black?

Am I looking at the right position? Isn't Black just better after 11...c4 - ?


Yes, I wrote down the line wrong.  9.dxc5 Nf5 10.Be3 a6 and now 11.Ba4.

By the way, is there anything wrong with simply [9 Be3 Nf5 10 0-0-0] 10...Nxe3 11 Qxe3 cxd4 12 Nxd4 Bc5 - ?


No. That is the recommendation of Avrukh Smiley

However, because White can start by playing 9. dxc5 Nf5 10. Be3, and here 10...Nxe3 is not good for Black. Therefore, Avrukh recommends instead that Black plays 10...a6. In that case, White can transpose to the variation mentioned above.

I agree, after 12. Bxc6 bxc6 I can't really see anything promising for White and Black's king is quite safe. The rook will remain on h8 for a while, but Black has a stronger attack and the bishop pair, open b-file and e4-square.

I was looking at this variation with Stockfish 8 after 1. e4 c5 2. Nc3 Nc6 3. f4 e6 4. Nf3 d5 5. Bb5 Nge7 6. exd5 exd5 7. Qe2 f6 8. d4 Kf7 9. Be3 Nf5 10.  O-O-O a6 and now instead of 11.Bxc6 it claims 11.Ba4! is quite a bit better for White.  Is it missing something?

I haven't got a chance to try this variation OTB for Black, and don't play 1. e4 as White. I am not sure how common this variation with 7...f6 really is. Not the most usual one at least, I suspect, meaning that even if you prepare for it as White, you might not get to play it at all.

Ah ok, we are talking about the sub variation 9.Be3

Will have a look.

Update: yeah the line is 0.00 but White can hope Black might go wrong in an OTB game I agree, probably more of a try for blitz or rapid. Decent practical try.
