i'm sorry, i have almost completely forgotten the action up to the river. i do remember that the pot was pretty big, but that's not really a factor considering there's no way i'm folding this.

we're four-handed on the river, i'm on the button with A-2-7-8 (suits are irrelevant). the final board reads A-3-5-6-9, giving me the nut straight and the second nut low.

two checks, the guy on my right bets. am i raising this or calling?

considering there were no flush draws on the flop OR the turn, i am pretty sure both players will call if i call--they seem to have shown obvious interest in the low, and the river was the 6, so it might have counterfeited 2-6-x-x.

this might be standard but i was pretty lost on the best course of action. i mean, if i had the nut flush, raising is way obvious since i can't get quartered for high and am on a complete freeroll to scoop or three-quarter. but, since i am able to be quartered for high AND lose half the pot or get quartered for low, i really wasn't sure if raising was good.

I like a call here. If anyone behind you has nut low,
they will likely raise, which is fine.

I don't think you'll be quartered for the high, but at
the same point, with 4 still in, I don't think you're
winning the low either.

Go for the overcalls and let them build your high half
of the pot, and if they raise their wheel hands, all
the better for you.

Plus, unless I'm off, the river 6 wouldn't counterfeit
the 2-6-X-X because you show A-3-5 on the board,
so a 6-2 is still his low, even without the rivered 6, no?

The only way the two people behind you are folding (whether you raise or not) is if they don't have the nut low and/or a high hand that they think will win half the pot. Therefore, I don't think you are losing any bets if you raise the pot here, as they will either call or fold (or maybe even raise it themselves) regardless of what you do, so I think you should raise it up. 8)

Can't do the math to see what it means if you get quartered (as you haven't indicated how much is currently in the pot)... :?
