Heres my 2 cents on AK, granted I'm relatively new to cash games.

I started off playing lots of low stakes SNGs, where after a few blind levels top pair is great and AK is strong. But in cash games, you already said it. AK wins small pots. So keep the pots small.

1) 3-bet flop. Min preflop reraises are weak, if this is AA than so be it. Looks like AK to me too.

2) When I'm OOP on a hand like this, I like to check/call flop and lead the turn, fold to turn raise. Dunno if thats a normal line but its been working for me so far at 50NL. Oftentimes they fold, and if they just call it usually means im ahead.

3) Check behind on turn.

4) Check flop. Mutliway pot, you didnt raise preflop, no one will belive this flop helped you, and anyone with a pp will stick around.

5) I think I fire a second barrel here, trying to rep an overpair. But I don't think your line is necessarily terrible, esp if this guy is a calling station.

6) stupid shortstacks. Played fine.

Also, when you do bet again on the turn, I don't think you have to pot it. A smaller bet still denies people the proper odds to call and doesnt bloat the pot.
