I'm in the process of a slump so I've been thinking critically about a few of my plays and was wondering whether I might have identified a source of the spew. I've been dealt with a lot of premium starting hands lately but I can't figure out whether I'm making the right calls or should be folding. Here are two examples:
UTG+1 dealt AK

and raise I have 3 cold calls plus the blinds.
Flop:
5

2

j
I bet 3 call.
Turn
5

I bet one caller and a lag on the button raises. I call thinking that the pot is so large and I shouldn't fold after betting.
River:
K
I check button bets I call.
Second situation most of the players are passive and call frequently button is a new player but well recognized in the card room (I'd never seen her but all the dealers seem to recognize her)
K

K

in the small blind. Button bets I raise someone else caps. 5 handed. (19 bets)
Flop:
7

2

4:

I check and it goes to the button who bets and I raise making it two for everyone and get one caller from middle position. (25 bets)
Turn:
J

I bet middle calls button raises I call. Middle folds.
River:
2

I check button bets I call.
I realize we're not supposed to be results oriented, and I obviously posted these because I lost, but I can't figure out whether I'm playing poorly or if I'm just getting unlucky.
