You didn't say if this is online, home game, or card room. I'll assume card room since you don't have info on V.
OTF, V's range is an over pair like TT, JJ, a set, with lesser probabilities of AX
, or possibly SC
like a 78, 89, T9 or even lower probability of A9s in
or
or way down the list, A9o.
OTT, of course the A9
gets eliminated. If he is a rock, there isn't a 2P hand he should be holding and check raising other than A9. The only overpair he could have held that gave him a stiffy on the turn is AA but his lack of action pre doesn't fit that hand. And the only SC that still makes sense if 78.
Even rocks can get excited enough to take a semi bluff lead when they have the double draw of FD and OESD. So his actions fit 78
fairly well.
If V flopped a set and is protecting against the possibility you are on a heart draw, the second x/r makes no sense. He would have led out on the turn because he has already shown fear of the FD. So I'm moving a set to a lesser prob.
As a rock, the second x/r makes no sense for him to have TT-KK because he would fear you called with AX
.
I think I've talked myself into believing his is on a stone cold bluff, semi bluff 78, A9, or maybe a set and the set possibility is low enough that I have to risk my whole stack. with top 2P.
Have I over thought this?
