AKs put to the decision...

[Aviston]

Alright, I'm yet another limit player who wanted to spice it up some. First couple of orbits, no solid reads. I haven't seen anyone get out of line yet.

Ultimate Bet No-Limit Hold'em, $.25 BB (10 handed) converter

CO ($6.45)
Button ($44.50)
SB ($6.18)
BB ($6.65)
Hero ($28.50)
UTG+1 ($15)
UTG+2 ($46.50)
MP1 ($13.10)
MP2 ($24.75)
MP3 ($28.45)

Preflop: Hero is UTG with A[img]/images/graemlins/spade.gif[/img], K[img]/images/graemlins/spade.gif[/img]. UTG+1 posts a blind of $0.25.
<font color="#CC3333">Hero raises to $1.00</font>, UTG+2 calls $1.00, MP1 calls $1.00, <font color="#666666">1 fold</font>, MP3 calls $1.00, <font color="#666666">1 fold</font>, <font color="#CC3333">Button raises to $1.75</font>, <font color="#666666">1 fold</font>, BB calls $1.50, Hero calls $0.75, UTG+2 calls $0.75, MP1 calls $0.75, MP3 calls $0.75.

Question #1: Is my 3-4 x BB raise from UTG with AKs standard?
QUestion #2: In limit, we pretty much cap with AKs. After the button's re-raise, should I be pushing here? I am destroyed by AA/KK and slightly behind all other PPs. Does the chance to pick up this pot preflop outweigh me being up against AA/KK?

Flop: ($10.85) A[img]/images/graemlins/heart.gif[/img], 4[img]/images/graemlins/spade.gif[/img], 5[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(6 players)</font>
BB checks, <font color="#CC3333">Hero bets $5</font>, UTG+2 calls $5, MP1 folds, MP3 folds, <font color="#CC3333">Button moves in with $42.75</font>, BB folds, Hero ...?

I didn't really want to build the pot with 5 others in, so I bet slightly less than half the pot to get a feel for the other hands. The button's all-in seemed probable with AA/AK. With two people liking their hands already, it seemed a bit premature to push with AA however, so AK felt a bit more likely. UTG+2 could have a weaker A, or perhaps 44 or 55 for a set as well. Is this a fold?
