Call? Did I do anything wrong beforehand? Should I have reraised to isolate preflop? I decided since AK isn't a hand unless it hits I should just call. Weak-tight-passive?

Preflop I don't mind the flat call.

The flop isn't as nice as spot as it might seem. PF raiser makes his mandatory pot bet, which raising the hell out of is fine, but once a preflop smooth caller smooth calls your raise (that's a smooooth fella), that's usually trouble.

This means a wider range than the UTG raiser preflop, and on the flop I'd expect something like TT-99-T9s-QJ-KT-KQ-KJ. The hands you beat being somewhat less likely than the others (sadly).

edit: I'm certain some will find good reasons to call, and I'd like to hear them, because I'd be aching to call in your spot, but lacking a good reason to. Maybe you had a read on SB that could help us ?

Basically you are beat here unless SB is a huge clown. So if he is, call, and if he's not, fold. Your play seems fine.
