3-6 stud hi lo on full tilt.

a queen raises and i reraise with split aces.

a :hearts6: calls the double raise as does the bring in and the original Q.

i bet on 4th st and the :hearts6: calls after catching a :hearts10:

on 5th he catches the :hearts8: , his third heart showing.

i bet and he raises. i still have a pair of aces. what would u do?

remember the :hearts6: called a double raise on 3rd and that the pot is big at this point.

First of all, I don't think you should bet into him on 5th in that spot. Either check-call or check-fold. It's hard to answer your question without knowing how many of his straight and flush cards are still live.

He may have a made flush here, or he may have something like 5 7 or 4 5 in the hole with a 4-flush, giving him a bunch of draws. Either way he's a favourite against your hand unless you picked up a low draw along the way. If alot of his hearts are dead, you can probably justify calling the raise (but folding wouldn't be too bad imo). If not, it's definitely a fold and wait for a better spot. Basically, even if your aces are the best hand right now, you're probably not a favourite to win the hand, and if he already has the flush you're drawing virtually dead. So this is not a very good situation to be in!

You have not provided sufficient info in order for us to accurately advise on our thoughts for how to play this hand. As this is Stud 8, we need to know ALL the cards that are already out there, especially your own (it is good to know all of them in Stud as well...).
