I think fold turn is likely fine. I highly doubt he is bluffing and also doubt that he raising worse for value. Not impossible of course. Anyway, assuming he just calls turn I would definitely ship river on that river card.

I don't think I can get away from this hand on the turn 3-way. What range are we giving them on the turn for shoving? Other than 5x which I think calls more than it raises, I find it hard to put them on too many value hands.

I think I'd fold there. When I get raised on that low nothing board I think its 5x, FH or A2 or sometimes occasional spaz with air. He's not jamming 99 or 4x or anything is he? I've never played NL100 but at my stakes its unlikely.

One of those spots I would fold versus an unknown.

It's hard to see him doing this with TT when he's way ahead way behind. He probably will have the straights in his range as well as 65s 54s A5s too, I think we're just relying on him making a ham fisted bluff with air if we call.
