Kinda different AK hand, play-along

[Harv72b]

I told myself that I was going to get some sleep tonight rather than play, so of course I found myself on a table; I rationalized that it was okay if I only 1-tabled. [img]/images/graemlins/grin.gif[/img] Pretty detailed reads on both villains as a result.

Reads: BB is what every loose/passive calling station dreams of one day becoming; he's seen every single flop since he joined the table, regardless of the number of bets to him preflop, to my knowledge he has never folded a pair, and I've seen him call river bets with Q and 7 high. At the time of this hand he'd been there for about 20 hands. SB has been at the table since I got there (about 60 hands) and is very LAGgy--she's VPIP'ing around 38%, PFR 13, and a relatively low 1.5 AF which is being brought down by her refusal to fold whiffed overcards or pocket pairs with overcard(s) on the board. She will bet every street until raised after raising preflop, although she has figured out in the last few hands that it's not worth trying against the BB. I've happened to have several strong hands from UTG since joining the table; as a result, I have PFR'd from UTG 4 out of 6 times. The seat to my right was empty for two of those raises, and I think that SB is starting to take me raising her blinds personally (she already busted my AJ (wound up with top two pair) with a Q8o). However, she has not 3-bet any of my raises up until this hand. And so we find ourselves here...
