Had only 14 hands on opp, he seemed like a LAGG reg: 33/20 AF was ~2.

Was going to try to check/raise all in the flop to mix it up but I guess I should usually lead there vs unknown?

I turned the flush and I bet half-pot, he flatcalls. River is a Q that could possibly complete a straight. The question is, are people raising straights on this board?

I count out all sets as they are raising the turn most of the time. QJ wouldn't check behind on flop. AQ/AJ probably repop it PF or raise turn anyways if he calls with it pre.

That leaves me with KTs, KTo for a straight, or high flushes.

So do we fold, flatcall, or shove ?
