Alright everyone knows who Stinger is obviously and he's just sat down at my table 3-4 hands ago in the 5k last week. Our table is pretty tough with JP Kelly, Sam Chartier, Dipthrong, and Huy Nguyen.
Blinds are 300/600 and we're about 10-15 seconds from break when the dealer starts the shuffle for this hand so everyone's already itching to leave/halfway out of their seats. I know Stinger is probably aware of this and expect him to open much wider than normal (he's one of the few who doesn't seem to be halfway to the door).
I've been coached by Timex for a few months who's one of his good friends and I also was talking to Timex on Skype once when he was at Stinger's apartment so there's pretty decent chance he recognized me but I'm not certain. I assume he thinks I'm a standard MTT player who thinks like most do.
It folds to him HJ-1. He has about 20-22k and he makes it 1400. I have ~17.5k and look down at Q

J

in the HJ.
Although I think a 3bet is obviously profitable I'm not sure if he'll think the same thing I do and think I'm trying to just steal his lighter-than-usual open and thus 4b with a high frequency. Additionally, the bb in this hand is a huge dolt who will defend with any two cards that are remotely connected ie (95o, 64o) etc. He's already shown down some pretty bad hands in his blind defense. So I elect to call. BB also comes along as expected.
Flop is Q93r. BB checks, Stinger bets 2200, I think for 15-20 seconds and call, BB folds.
Turn is a 5 completing rainbow.
Stinger thinks for 15-20 seconds and bets 5800 into a pot of ~10k. I have around 14k back. His sizing definitely threw me off quite a bit because even though he's a cash player, stacks make it so that bet is reallllly awkward and I think he's pretty aware of that.
So what should I do? I've heard call, fold, and shove from a few people I respect so think it's an interesting, if seemingly simple spot.
