What tell do you have from a 3 handed game that you can insert into a 8 handed game?

I dont see the point of calling with 97s at any point in time during this hand. I gotta believe preflop you are behind.

Could he be holding Ax, any 2, TT-AA, or any diamonds on the flop?

How are you calling the check raise turn?

I'm just very confused the whole way. I don't think you have enough information about this guy yet.
