I'm feeling pretty sick right now, it was another one of those sessions where nothing goes right and everybody is outflopping me when I hit something. Is this just variance or what?

Hand 1: Standard AQ raise, called in two spots. Flopped top pair good kicker, but I checked behind on the turn because I don't see too many hands I beat calling, and I also checked for pot-control reasons. He made an awful preflop call and an even worse call on the flop. I guess I gave him a free card to draw out but I really didn't want to play a big pot with just a pair and couldn't stand a raise. Should I have bet the turn? And as played this is an easy river call right?

Hand 2: The previous hand I had taken a decent pot off this guy and he was semi-shortstacked. I called from the BB with KQo, flopped top pair and went for the check raise. I figured a standard raise would commit me to calling if he came over the top so I just decided to put him all in. He ended up having the case two kings in the hole and I was drawing dead. Nothing I can really do here, right?

Hand 3: Standard AK raise, and the BB defended. Good flop for AK, only worried about 8x, and I figured he was calling me down with Kx which was why I kept betting. His river bet is suspicious, but I looked him up and paid off his three eights. How was my line on every street? Anybody fold the river?
