AJ turn play

[Worm75]

Bet looks really weak, either that or he is trying to induce. A lot of times this is a draw picked up on the turn though, where they are trying to either take the pot down or get to the river with their draw cheaply.

However I don't see what option hero has other than flat-calling cheaply and hoping to hit your 2 overcards/fdraw, though because if the guy can hand read and has something like a small pp, he's not folding after you checked through a drawy flop.
