@redrooski24@Kyyberi I think this is a poor hand to have in this spot. The KQ9sxs effectively gives us 3 connected cards and a suit out of position. We call this pre heads up we are out of position and really don't flop well and if we do, we are never going to be locking it up vs a stack off range. Being out of position equity realisation is a difficult thing to do also.
If the 3h is a club or something 6+ that interacts with the 9 at least then I lean towards calling as there is a bit more that can happen with the hand. Take the 3h and make it a 7c and the hand is significantly better. Not just a little, like a lot better.
As it is these hands I see if we are calling pre we are check folding a lot, check calling some flops and turns go check check and a lot of rivers we don't know where we are at; if it goes check bet call flop, check check turn, then check bet and decision on the river, this is not great; more than likely we are behind but call with something in case they are bluffing.
If the flop is a checkraise get stacks in we are often enough going to be freerolled or dead if the player is competent. It requires some kind of combination of spew and cooler on their part to make this a profitable scenario. Ex: Q94sxs and they have 94T8xxss for bottom 2 a flushdraw and gutter.
Propokertools has this hand flopping ~47% equity half the time on the flop against an 80% open. It is 50% vs a 100% open.
