He has 9T spiked his ten, or and is seeing how it holds hopping the suit scares you. Raise/call.

I'm really tempted to raise, but I'd probably just call.

Thats tough. Do you have any reads? I think if your beat here and raise your getting 3 bet. If your ahead hes just gonna call your raise. So when your ahead youll be making 1 extra bet but when your behind your gonna lose two. Because of this and since the river card completed a couple draws i would just call.

Call. You would hate to be 3-bet here (unless you don't mind folding if that happens).

Raise. Your average player will check raise you if they hit a flush.

Raise/call. I'd expect a normal player to check-raise here with a flush, expecially a runner-runner flush. I'd expect to see JT more often than a flush.
