25nl: practicing lag play, easy AK fold?

[dukemagic]

So I normally play 50nl and have just moved up to 100nl. However, since I don't have very much on Stars at the moment, I've been practicing my lag play. I'm normally a 19/12/3 full ring player, but I've been working on playing hyper-aggro (for me, anyways) at 6max 25nl.

During this session, I've been 36/26/7 over a decent amount of time, and have been running the table over, buying tons of small pots. I haven't shown much down, and I've made some big check-raise bluffs and b3b bluffs that haven't been shown down. I actually haven't had many good hands. I finally hit AK. I'm still adjusting to lag play, and wasn't really sure what to do here, with a hand that had showdown value but wasn't really that great. I decided to call the turn hoping to check behind on the river, and when he bet the river, I figured I was beat. Do I fold the turn? Do I 3 bet the flop? Push the turn? Call the river getting 4-1? Thanks for the help.

Oh, reads: PT has him as being 18/2/2. Can't say I had any reads at the time, except now that I think about it, my thought process was kind of like, (on turn) "well, I've been running the table over, so they're probably trying to make a move on me now. I call!" (on river) "oh wait, they haven't tried to make any moves yet. This is probably a huge hand. Fold!"
