I think you have to give Villain's a wide range for spew on blind v blind situations.

H1) What range are you putting Villain on OTF that a Q is so menacing? I understand that KQ is in Villain's range, but so is JJ-88 at minimal. Maybe those don't donk OTT, but maybe they do. Maybe random Qx (including AQ) floated OTF.
I think station down here. There aren't too many 3's in Villain's range and TPTK will catch all of Villain's bluffs (which I find many Villains do way too much in blind battles).

H2) How many 6's are in SB's range? Why are you so worried about a 6? I think Villain bets AQ here every time, and JJ,TT,99 sometimes.
I'd station this one, too.


Given that there is a FD to semi-bluff on both hands OTT, there's even more reason to continue.
