6max HU vs aggrofish

I would tend to call this and fold e.g. 67. His range is most of time weighted toward draws and T7 will have enough equity. Also I would not be surprised of some 6x from villain. It makes zero sense, but still I see it from fishies. He can also have some better made hands sometimes, but folding middle pair here is too weak.

I have to agree with you since 2 hands later as I said he turned up with a draw in a similar spot. But the thing is it was probably 1st or 2nd hand of a HU play and normally I try to assess what type of player he is before making plays for a full stack (I play without HUD) thus I folded. Vs unknown you still call here?

Well you never should have unknown player when in HU phase. Of course some players change their play style a lot when in HU. But overall if villain has been aggro earlier he is likely aggro in HU also. If he has been more passive then I could be bit tighter on first time he makes such move. But versus most villains I would tend to still remove strong made hands partly.

Yeah, with all the draws around, i'mma call, but it's close tbh. He can be shoving Qx also as he's scared of the drawy flop. Usually weak Qx. As QJ, KQ, QT, Q9 have more back up equity. However, he can also have draws(most of the time imo) and also 6x. With the aggro reads you have about him, I go more towards calling.
