# Do you have to teleport the number of squares listed or is it a max range?

I had a little discussion about the distance my Swordmage can teleport after he used his Vanishing Blade. Its effect says (in part):

Until the end of the encounter, whenever you hit an enemy with a melee attack, you may teleport 3 squares as a free action.

Of course, I can decide whether I want to take this free action or not, but what if I just want to teleport 2 squares?

So is the stated 3 squares an absolute distance or is it a range within which the destination of my teleport has to be?
