Hand 1, his line doesnt really make sense for anything other than a flopped flush, or maybe AJ but i think its a fold.

Hand 2, why didnt you raise the flop? His bet seems like a FD and i think you are letting him get off too cheaply, and your villian dead posted the BB UTG, which makes me lose some respect for him. When the diamond hits i really dont like that bet and as played i think you have to fold.

Hand 3, his line is screaming set, so i don't really like the push. maybe he has KcQc, but you are way behind that too. So, having to call 56 into a pot of ~161, i think its a fold. You are almost certainly not getting a free river card, and not making enough on the times that you hit the club on the turn.

Hand 4, it kinda looks like he is floating you, so i like a turn call. River is tricky basically regardless what hits, so maybe a turn lead is good? If we bet turn and he raises we can fold easily, and he would probably check down river without a better hand then us if he just calls. I dunno, im undecided on this one.

Hand 5, i dont think that is a particularly good river for you because it only makes us beat A10 which would almost certainly bet the turn. I think his range is heavily weighted to flush draws or air because a set has to bet the turn but something like 10dXd could check through. I think the best line here is c/c because nothing we beat calls a bet except maybe AQ. I dont think a fold would be right on the river but i expect to be shown a flush a lot here.
