Re: Two sets
 

Hand 1:

Cap the flop. UTG raised once, he'll very likely call two cold. UTG+1 already cold called two, so he'll even more likely cold call two more. So you have middle set, 7 outs to fill up on the turn, and you'll have 10 outs to fill up on the river. Even if they all already had flushes, you cap this flop for value.

On the turn, the fact that UTG+2 is almost all in will come into play. Because UTG and UTG+1 both only called your bet, I would put UTG+2 either on tilt or on a good flush. I would probably three bet here because I wouldn't think UTG or UTG+1 could beat my set.

On the river it looks like UTG+1 holds a 3 and hit a straight, so I wouldn't raise. UTG probably has a Q, maybe Q6.

Hand 2:

Three bet the turn if you're going to bet the river. I don't want to say any more now.
