pfr is competent. 13-9-3, 55% flop and turn cbet. UTG/+1 range is something like AQs+/77+
first caller is 36-4 station.
Players behind are regs, but not likely to squeeze in this spot without the nuts.
When villain cbets this flop into me and a station fish his range is pretty much 99/JJ+/AKhh/AQhh and i don't think he's folding to a raise plus if i complete with a non-diamond then he's going to keep betting. backdoor flush draw too Turn is bingo, raise size?
when he barrels this turn he's pretty much sets and overpairs.
