Accelerated Dragon & the Yugoslav Attack

I've been playing the accelerated dragon recently, and I know that white shouldn't be able to set up for a yugoslav attack. However, sometimes the first player gets it going, and I'm unsure how to punish it. 

 Last time I faced it, I played Qb6!?, which according to the computer isn't best, though the tactics are complicated enough that I still usually do alright (more often than not coming out a piece ahead). Is there any real way to punish the slow f3, or should I just castle and play ...d5 as per my plan?

i'm pretty sure you just castle. exact punishment depends on his next move. Usually the most principled move is d5: compared with regular dragon/yugoslav attack, you save a tempo because in dragon you play d6 first

Actually, more often than not, white will establish a Maroczy Bind Setup, which tends to be drawish... Anyways, if white doesn't play 5. c4 and instead opts for 5. Nc3 opting for a Yugoslav, then you should be doing good after 8... d5 because of the fact that you didn't waste a tempo playing d7-d6

Just castle and play d5. The whole point of the accelerated dragon is that you get the d5 move in one move and not in two move.
