Playing the 2nd best hand

[RayGarlington]

If the 8 hand is a rainbow with no higher cards, your equity is about the same with him in or out (about 30%). Better to have him in and contributing.

If you give him credit for something, your equity drops to about 25%, which is worse than going heads-up against the Aces. If you wouldn't go heads up vs AA then you shouldn't here either.
