Yesterday I played this very interesting hand.
05 1 shallow 6 max ( max BI = $40), effective stacks = $140.

Hero (cca $140 stack) opened JT99 ss UTG and aggro big stack (he has cca $140) BN 3-bets (pot size to $7,5). It's HU.

FLOP ($16,5): Qd 6c 9d Hero checks, BN pots, Hero calls (I think this line is fine not having FD)
TURN($49): 3s Hero checks, BN pots and now....

I play vs QQ (I hope not, but I still have 7, if not 9 outs in that case), or vs AAQ:dd or vs KKJT:dd or vs (66+, Q978:dd type of hand)...
Villain knows I am capable of floating here, his potting does not mean he is super-strong as this can be protection bet with AAQ:dd.
Do you ever worry in spot like this one after c/r jam OTT? Would you played this hand some other way?

Thanks
