Look at it like that.
He is strong enough to x/r vs 2 villain on Turn. Don't think he is doing it for bluff too frequently, and not with just a pair.
He can be slowplaying flop with str8, two pair, set. Then, x/r Turn. Betting River. His line looks v. strong.
They are both capped after flatting preflop. They either have sc's or pp and the flop favours them.
You only beat bluffs on River, cause any Kx lower than yours is not raising the Turn. And missed
draw probably bets turn, instead of raising.
I would most likely fold the turn already with in mind he/she isn't check/raising as bluff in a multi way pot and you beat only a bluff. River is a easy fold for sure.
