I'm short stacked in the BB with an M = 2.6. Villain raises from HJ. I have ATo. Insta-shove and expect a call or fold? Usually, I would expect AT to better than a large stacks raising range from the HJ. But this opponent hasn't been raising much from late position, instead opting to limp with vulnerable holdings and play post-flop.

Reads: Have seen 52 hands with Villain who is playing 23/6. He has not attempted to steal once, but he has been cold-calling raises and limping from late position. Of the three raises, two went to show-down and was TT, the other was 77 (for a flopped set). Of the late position limps, one went to show down as JTs.
