A 15/8 raises utg and calls a 3bet oop. His range is going to be pretty tight, although bad players at the micros have a tendency to set mine far too much oop in 3bet pots. I'd say range pre is {99+, AJs, AQ+}, with maybe 22-88 also thrown in there.

I doubt villain donks this flop if he hit his set or with overs in a 3bp but would donk it small with TT-QQ to "see where he's at". This makes the turn and river particularly shitty, especially given his c/c turn and shove river line.

Be interested to see if others think the flop call is optimal, as I'd be tempted to raise and get it in.
