"I have a good recollection of my last meeting with Kasparov in the 1992 Paris Immopar trophy. By playing 1.d4, Garry was certainly expecting to meet my favourite Queen's Indian defence, but that day I had prepared a small surprise in playing the Bogo-Indian. It was clear that he didn't expect it. That gave me a 'psychological edge' even if later I lost the game. Fair enough, but we can consider all that."

I wonder if 10..Ra7 (a flexible move, getting off the long diagonal and seeking more activity on the c-,d- or e-files) along with ..0-0, and playing for an earlier ..e5 is viable. I think Black would be better keeping the LSBs on, or exchanging his for a White N if he locks White's pawns on light squares.
