Close or actual cube decisions = decisions where the equity swing (between
the right one and the wrong one) is smaller that the threshold.

There's no easy and realiable way to estabilish with an algorithm if
a cube decision, even if "easy" in terms of equity/error, could be a
tough one for a human player. Hence two approaches: either you count
everything (Snowie) either you count only the "close ones" (gnubg).
