Since starting poker, I have always played HU hands by either folding or raising (on the advice of a friend).
I've just reached the Heads up section of HOH II where he advocates always calling from the small blind/button with ATC unless the big blind is persistently re-raising you.
I'd be interested to know how others play here and if you feel that Harrington's HU strategy for MTTs translates well to online SNGs.
Thx.
