Do you fold here?

Villain is pretty good from what I've seen from him. He plays 25/22 and seems to be thinking from a bluff i saw earlier. Hasn't went to SD much

lol sick play by colums, but my first reaction is he made a flush or maybe straight, either that or turned Tx into a bluff.

and it looks like you can have a big hand. i guess i would fold without QJ or some sort of "spidey sense" going on that he actually wants a fold, but it definitely seems weak...

yeah its a fold, the flop check brings a turn makes a lot of his range playable e.g QJ, A.x D

I hate checking sets, I never do it now

looks like a backdoor flush or set....i don't think you can call this. do you know if he has a read on you?

yeah this is definetely a fold.
