His action screams a draw, and QJ is the most likely one. Unless he has like KT then 2P is unlikely based on actions. I probably cant b/f because even if I bet something like $9 and he shoves, then its only $19 to win $63 and I have a set. The question is more does shoving get called by enough of his hands that its more +EV than just betting $9 and getting called by his 1P hands. Also is betting at all +EV compared to just checking behind.
