At NL50 I am not sure if it's good to get it in vs a shove after a 3bet w AK, though at NL200 I get it in here all the time and am happy about it.

But if villain bought in for such an odd stacksize, only played a few hands, and plays a hand like this I'm getting a bit suspicious and would just call it off.
