Don't show your opponents' hole cards unless you have a good reason to.

The reason that high hands are unplayable in high-low no-qualifier is that they have essentially no chance to scoop. They are more playable in stud/8 because they have some chance to scoop when the low hands bust out. That said, most players tend to overvalue high hands, so a lot of them lose money on them. I would expect this to be especially true at the micro-limits.

Fold third. You have no credible shot for high and there are two Aces yet to act.

I'd lean towards checking fourth. It's true that the scary boards have checked, but they're still a little scary, and I'm not that excited about your prospects in either direction.

Fifth through seventh are debatable, but I won't argue with any of them.
