HU Traps Gone Wrong

[MrFeelNothin]

The first one I think I played very well, the second one I seriously erred on at least two streets. Here goes:

Party 50/5, 9 players left, 15/30, relevant stacks:
Hero(990)
Button(1080)

2 folds, Hero(K [img]/images/graemlins/spade.gif[/img]K [img]/images/graemlins/diamond.gif[/img]) raises(90), 3 folds, Button calls(90), 2 folds.

Flop: 5 [img]/images/graemlins/diamond.gif[/img]9 [img]/images/graemlins/spade.gif[/img]4 [img]/images/graemlins/spade.gif[/img]
Hero bets(75), Button calls(75)
Im pretty sure this flop completely missed my lone opponent, I want it to look like I have AK and missed as well.

Turn: 8 [img]/images/graemlins/heart.gif[/img]
Hero checks, Button is all-in(915), Hero calls.
I checked to feign weakness and was planning on checkraising all-in, I was very happy when he moved in as I was sure I was ahead.

River: A [img]/images/graemlins/heart.gif[/img]
Button shows A [img]/images/graemlins/diamond.gif[/img]4 [img]/images/graemlins/diamond.gif[/img],two pairs aces and fours, Button wins 2025 chips
Not a bad beat story, I was happy the way I got my money in, but I could have played it faster and won a small pot, should I have?

Party 30/3, 9 left, 15/30, relevant stacks:
Hero(730)
BB(1635)

5 folds, Hero(A [img]/images/graemlins/diamond.gif[/img]9 [img]/images/graemlins/club.gif[/img]) raises(75), 2 folds, BB calls(45).

Flop: A [img]/images/graemlins/spade.gif[/img]10 [img]/images/graemlins/heart.gif[/img]K [img]/images/graemlins/diamond.gif[/img]
BB bets(55), Hero calls(55)
Possibly misplayed, was planning on raising turn.

Turn:9 [img]/images/graemlins/diamond.gif[/img]
BB bets(55), Hero calls(55)
Definite mistake, for some reason hitting my two pair caused me to want to slow play more, although it shouldnt have made a difference.
River:3 [img]/images/graemlins/diamond.gif[/img]
BB bets(150), Hero is all-in, BB calls(395)
Ok, something about him betting out on this river after getting smooth calls on the flop and turn should have screamed out danger, but it didnt. This street is a clear call I believe, correct?
BB shows 6 [img]/images/graemlins/diamond.gif[/img]7 [img]/images/graemlins/diamond.gif[/img], flush king high, BB wins 1475 chips
