How did he respond to our CR? If he just called we may have a shot, 3 bet and we're in trouble.
Again without playing a single hand against villian it's hard to really know. We've all seen people who will go to the SD with AK or AQ or less at times (as surely some of us have ourselves

).
The main problem I see is we don't know a thing about our opponent (our only real advantage here is he dosen't know us either which might actually help us) But, some will fold like a cheap lawnchair here, others won't. Plus we're not talking about a big pot either that we really need to go after. While I will agree when moves like this work it is pretty satisfying but, we can wind up taking more of a risk than we need for an average or even less than average reward.
Now don't get me wrong Stick, I don't hate the move... I've attempted similar and/or worse ones myself at times

. However knowing how you've been running, I might be leaning more in the side of caution. We're basically entering the FPS zone here which we all know how
that tends to work out.

So part of me is wondering if things like this might have a slight impact on your recent run.
