Well, I'm not folding!
I think we have maybe 54% equity if he's raising with his sets & plays hands like 98s, JTs, 76s & raises those, along with TT. Maybe even T9s with a BDFD & BDSD.
You can decide he has a set & flat to try & catch a king - 4%. Or, you can assume he has 2 pair [2 combos of 98s] & flat, again looking for a king, or a deuce - 10%. Or, you can assume he has 29 of the 38 combos I gave him that you are ahead of & you have 70% equity, which usually doesn't change much ott.
If we decided what we were going to do if V raised b4 we bet, we can
smoothly cut out 7 reds and slide them in.
If we flat & the turn is the 2
, are we going to bet or check & let him see the river for free with his draws?
It's extremely hard for our hand to improve vs. a set & not much better [6%] vs. 2pair. We could actualize our equity vs. the bulk of his range I assigned, which we are ahead of, and raise, but if he's the type to 4! with JTs we are in trouble. Otherwise, we could fold to a 4!.
But first we have to believe V calls $10 pre, when nobody else has called & only the blinds left to act, with 76s, 98s, JTs, etc. He may have flatted pre with TT/JJ/QQ.
Like Nogyong says: It's rare to find a V that bets 3 streets with a worse hand in LLSNL games.
