after 10...a5 follows 11.Nb3-a4 12.a3-Bd6 13. c5(!)-Bxc5 14.Nxc5-Qxc5 15.Rc1-Qa5 16.Qe1-c6 and now 17.Qd1 causes Black Headache with the black Squares. And what to do with the Bc8 ?!
Regards
To be honest I do not know this line very deeply, though I had considered 17.Qxa5 to be the main line (I guess there are a few games with it) with 17...Rax5 18.Rad1 Re8 looking fine for Black without any more analysis.
I suspect that you are right to try and keep the queens on, but it's not so easy for White after
17.Qd1. If Black is so concerned with the Bc8 he can play simple chess
17...d6 18.Qxd6 (otherwise Black has no problems)
Ng6 and now there is some branching, but Black will take on f4 is offered, and otherwise play a quick Be6-b3 followed by Rfd8. This seems perfectly satisfactory to me for Black, since White can't even control the d-file.
Play might continue
19.Bg3 keeping the bishop pair seems like the best try for an edge
Be6 avoids complications
20.Rfd1 Bb3 21.Rd3 Rfd8 and after the resulting simplifications, it's hard to think that Black has any problems with the endgame.
Of course 17...d6 is just one choice, and 17...Re8 may be OK as well, intending f6 and if possible b6/Ba6, otherwise d5. The point is that Black is up a pawn here, and so he has some flexibility in breaking the bind.
