Folding Nut low and Nut low draws

[bbartlog]

Guys I think you need to learn more about plo/8.

...says the guy with ten posts. As Rob pointed out, consistently folding the nut low 3-handed is exploitable by decent opponents. Now to be fair to OP, he specifically mentioned a situation where he suspected one of the other players also had the nut low (for some unspecified reason), so his fold might be good there. And it also depends on whether you're playing full ring or shorthanded, and how deepstacked you are.

I don't know how many times I have bet nut lows

Yes, there is an option between 'fold' and 'bet' known as 'call' which I often choose when I have the nut low, though as always it depends.
