Good play right?

villan is 24/20, which is why i reraise on the button with AJ. The guy has folded on the flop after hes been reraised twice already. Plus I'm feeling frisky. But this is a good play right? I mean I would put myself on JJ+ personally. My read is he has 99-jj, maybe even less. of course i cant rule out a set.

i think you are right and he'll probably lay it down... even if he doesn't you have what, potentially 15 outs? maybe only 12.

unless he has 8's a set is really unlikely.

Not a fan of the reraise with AJ there since he did raise UTG. As played it looks good.
