1) I fold, I think he'll rarely bluff that spot and I don't see worse hands that raise that river.

2) I call this one, villain is aggresive enough to bluff that river, raise a busted draw or "value bet" his AcXc. You only have to win that pot 27,6% of the times, villain seems bad enough to worth a call IMO.

Yeah. I have the Ac, but I think I still agree with your reasoning.

Opss, misread :P

AdXd still applies.

I think the second one is definitely a call, I think you're ahead way more than enough not to fold, and it's tough to get called by worse if you raise.

The first one is very close I think... against most villains I call getting those odds but I could see folding too against regular TAGs.
