1. I'd say don't 3bet the river if a 4bet will make you want to kill yourself.
2. I fold to the all in. Yes, he's a fish but his line screams the nuts/near nuts. I have yet to see this kind of line turn out being a bluff.
3. I fold the flop.
4. I'm def stacking off here.
5. Fine
6. I don't like it. What are you hoping for? AJ? Flush draw? Also, why are you short on some of these hands? Playing short gets you into pretty iffy situations like this.
7. Fine
