Thanks for the tip.  I briefly looked at 15...Bf5 during the game and almost immediately discarded it because of 16.g4.  Then I turned to 15...Rb8 and 15...Qc7 and spent my time only on those two moves.  Since then, I've decided that 15...Qc7 is better than 15...Rb8.  I'll take a new look now at 15...Bf5.  Initially, I still don't like letting white get the g4 shot in against my bishop, either on move 16 or perhaps after 16.Qc5 first.

I have a question about a line in the 9.O-O-O Yugoslav Dragon.  I played an IM yesterday, and predictably, I lost.

IM -  Lost Highway, game/90, July 16, 2005 

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be3 Bg7 7.f3 O-O 8.Qd2 Nc6 9.O-O-O d5 10.exd5 Nxd5 11.Nxc6 bxc6 12.Bd4 Bxd4 13.Qxd4 Qb6 14.Na4 Qa5 15.b3 

This is the position I want to ask you about.  I considered 15…Rb8 and 15…Qc7.  I played 15…Rb8, but now I’m not sure.  Perhaps 15…Qc7 is better?  Anyway, I lost in 34 moves, but not before missing a draw on move 28 that the IM pointed out to me immediately after the game.  He had missed it too, and only saw it after he moved.  I guess I must have believed his mistake was actually a trap.  But, all that is irrelevant to the question about which move is better:  15…Rb8 or 15…Qc7?

Thanks.
