[microbet]

I think any pocket pair > 3 is likely here. There's some chance that it's a low one and he's end up checking the turn. Some chance he'll bet it anyway. Some chance he has a big pocket pair and will either bet or check/call the turn. I think calling the flop is anywhere from ok to bad depending on reads and history. Given no reads or history it's probably close to neutral. Once he checks, the turn shove is pretty clearly +EV.

This is definitely one of those hands that I would rarely play this way, but once in a while you get the feeling it's likely to work.
