Only 8 hands on villain (he's like 38/14 over those 8 hands). BB is very spewy, and I didn't want him peeling with overcards/draws cheaply (I would have happily gotten it in against him if he shoved). When I raised the flop I knew I wasn't going to be sure what to do if UTG 3-bet, but I really didn't want to take a turn 3-way here when I likely held the best hand on the flop and he only bet half pot.

Ya.....

8 hands is not much of a read. But I guess u played it fine. Just make a note about his 1/2 pot CB and what he turns up with. HE may have 2 overs and FD too. U should be ok against his range.

The EV you lose by potentially making a really dumb decision if UTG 3-bets has got to be larger than the EV you lose by letting the donk chase some silly overcard draw.
