Your tables might be tighter than my normal tables (where a $12 open is often seen as a limp).
Anyhoo, it got a good result (narrowed the field to 3way), although I'm not sure it's the result I'd expect (especially with our raisey image, I'm surprised we didn't go multiway, which is not what I would want).
I think the SPR on the flop is such that we can plan to bet/fold on the small side on each street against this guy. We don't risk pot committing ourselves because stacks are fairly big, and this guy has proven to be a calling station (only showing aggression when he's ahead, so we can safely fold if he raises).
I probably bet slightly smaller on the flop so as not to build the pot huge (i.e. $20).
I would have just flatted the donk bet on the turn. My postflop plan was not to play for stacks, and yet now that is exactly what we are doing (we'll only have less than a PSB left on the river). I'm probably in calldown mode unless perhaps a draw comes in.
I would fold to the river shove. He has taken a very strong line (one that screams "I HAVE A SET!"), imo.
What was our plan on the river if he checks? Especially considering we have less than a PSB?
Raising the turn got us in a gross spot for stacks; did we want to play for stacks on the flop with just TP in an SPR ~11.3 pot?
ETA: Lol at saying Villain's line makes no sense. This is I-haz-a-set-101. They aren't playing back at you nearly as much as you think. Heck, they probably ain't even playing back at you, period.
