BB defense turns B2P 5-way

[kimchi]

SB is a TAG
HJ is a passive fish
CO is about 90/70/5 over a few dozen hands
Button (raiser) is 20/15/1.5

I've only seen button villain SD 1 hand on a different table (he seems pretty nitty). He stole from button with a weak Ace, flopped bottom pair, the flop was monotone, he bet flop and checked behind turn & river and won UI.

How about this turn donk? I had a feeling villain might check behind here. The board is pretty co-ordinated now and unless villain has an overpair or something like AT, FD or QJ I doubt he's betting much else, and I'm probably not going to get the opportunity to C/R and protect my very vulnerable hand.

If the board on the turn looked more like something he would bet again, then a turn C/R might have been better.
