I (personally) check with the intention of folding if it's one back to me.

I tried to put villains on a range of hands, given your reads. I put it into PS:

Board: Js 9d 2d
Dead:

equity win tie pots won pots tied
BB: 52.557% 52.14% 00.42% 12793101 102521.00 { 77+, A7s+, KTs+, QTs+, JTs, KTo+, QJo }
MP: 29.298% 28.88% 00.42% 7086138 102521.00 { 77-55, A7s-A2s, K8s-K5s, Q7s+, J8s, T8s, 98s, ATo-A7o, KTo-K9o, Q9o, J9o, T9o }
You: 18.146% 18.15% 00.00% 4452356 0.00 { 4d4h }

So I guess over this range, we have an 18.15% chance (~4.5:1) of either retaining the best hand or improving to the best hand by the river. What this is supposed to tell me I don't know. I just act like I know what I'm talking about sometimes.
