I don't actually see how you can be reading that set so easily. If button's willing to call every raise, yeah he could have a set, but also Ax PF. I think you have to C/R this instead of B3B.

If you check, and he's got his set, more than likely he's going to bet pretty weak to induce your raise. So do it. If he comes over the top of that all-in, you know you're beat (min. bet to re-raise AI is a big donk tell). Your hand became quite the clusterfuck with your lead out.
