tight is right?

Hand 1: cbet, as you played the flop just check/call. c/c turn, fold river w/o a good read. I don't think checking this flop is a big deal.

Hand 2: cbet, raise the turn more. check behind on the river.

Hand 3: given your stats your opponent probably has you on overs/pp so i think a cbet is good here. bet more on the turn. river is fine, but i would go for ~1/2 pot.
