AKs is actually a slight favorite over dueces and even an unsuited AK is less than a 60% dog to all pairs. It's no worse than 43% even if its unsuited and the PP is broadway (thus interfering with the straight draw) and the pair is of the same two suits as the A and K
In addition keep in mind AK is only dominated by AA and KK so playing it strongly preflop is usually wise because you have fold equity, you are representing AA or KK and worst has you likely are a coin toss. This is talking about when you are raising, reraising, and betting with AK -- not calling or checking
A sample hand from a session earlier this week
5/10 NL
MP opens for $50, I reraise from LP with AKo to $200, folds around to original raiser who calls
FLOP: 7
2
3
MP Leads out $200, I instashove for $825
I like this play because:
1) I took control of the betting preflop
2) My opponent just called preflop
3) Since I have AK it is unlikely he has Aces or Kings
4) If I had AA or KK in my hand, this is exactly how I would play it
5) His play seems to indicate a medium pair that is betting out for information rather than going the more expensive route of check raising
6) I don't think he can call my all in
7) If by some chance he musters up a call (I'll take note on this later and exploit him) I probably still have 6 outs to hit a King or Ace and take the lead. That win percentage combined with the fold equity by shoving easily makes this play +EV
Had I just called preflop, or not raised on the flop this play is obviously impossible and then the % matters that AK is a dog to a PP
Just a quick example.
