Hand 1: Good, but dangerous check on the river. Definitely cap this. The only hands I'm really worried about from UTG+1 is if he somehow flopped Quad 2's or hit 77. I think we usually see either trips (A2) or more likely a smaller flush.

Hand 2: Chip spewing. Don't raise the flop, and don't call the turn unless you are going to call the river UI.

Hand 3: Pretty good. I'm curious as to what people would do if MP1 bet this turn. I'm pretty sure I'd dump it. All my outs except for an offsuit king are suspect.
