hand 1 - Q8s - raise it up I like $6. Villain will have a tough spot with Ax, will call worse 8x and won't be 3b bluffing ever here.

hand 2 - sick spot. I mean villain has Adx, AQ, AA, KdK, QQ, 88, 99, 89, JdJ, TJs right? Turn is really close when he keeps betting, especially after that nit calls in position, river 2s changes nothing and you probably have to just check-call river vs a bet, and check fold if there is heaps of action.

hand 3 - preflop is a weird spot.
