I agree with Glenn. After his line   
12.         Bc2
13. Ba5   BxQ
14. BxQ   Rc8
There is now a threat of Bxa2 because of Kd7 winning pinned Bc7 so Ba5 is best.
After that Black has a simple plan of playing f6 a la French, to widen play for those 2 Bishops. And I think he is substantially better then.
I would love to see an answer for this cos it is a cornerstone of what is otherwise an excellent book.
Any ideas?

Thanks for the reply!  I was rather surprised to see the author of the book answering my question.  Now that's good value!  Thanks also to "Never1b4" for initially suggesting the Ba5 move.  I tend to rely too much on my computer's evaluations, perhaps because I'm not that great in "simple positions".

I too am quite pleased with the book.  Have been practicing the variations on ICC.  (Never knew the Bogo-Indian was so popular.)  Like the complete coverage!

11...Nxe5 is certainly an improvement for Black on Palliser-J.Houksa, 4NCL 2003. Burgess doesn't cover this as 8...Nbd7!? is very rare, whilst it's also worth noting that his fine and thorough book also underestimates the strength of Hebden's 8...Nc6 9 0-0! in the main line. Perhaps Black can equalise but in practice White scores well as the Black light-squared B lacks a good role.
Certainly I was concerned that Jovanka might play 11...Nxe5 when I intended 12 dxe5 Bc2! 13 Ba5 (and not 13 Rc1? Rc8) 13...Bxb3 14 Bxc7 Bxc4 15 Rc1 Rc8 16 Ba5. The light-squared B is perhaps more in the game than usual, but I'd still take White here, with Nd2-f3 and then maybe d4 or Rc2 and Rac1 followed by b3 on the cards. White just seems to have an easier position to play as is typical of the whole line.

I agree that the lines Palliser recommends against the Slav are probably only equal.  Still, maybe White can keep a bit of pressure in the line you give by playing (after 12...Bc2):

13. Ba5 trying to grab the QB file.  Play might go

13. Ba5 Qc6
14. Qb6 and at least Black as to be careful not to
allow a pin or give up the file.  Certainly White has no worries.

Whaddyathink?
