Just like Isk said, your glaive is essentially a giant lever. Where you put your forward hand determines where your power will be. Here's an 8 foot spear.
fig. A <-----|--|-
In figure A we see that both hands are towards the back of the spear. This is best used with palms down, what I call the "Oar Position". (Same hand position as rowing a boat with an oar) This is effective within a shield wall because of maximum distance. You also hold it in a high guard, with hands above your shoulders. This is most effective at blocking Javelins and quick, low power jabs.
fig. B <---|----|-
In fig. B we see that we have choked up on the spear, giving us more control over the lever by moving the fulcrum forward. This is best used with the forward hand palm up, and the back hand palm down, in what I call the "Reverse Hockey Position", because its like holding a hockey stick, only your favored hand is on the back of the spear, not on the bottom of the stick. How this position is most effectively used is in parrying, because if you have a good grip over your end of the lever, even hard red hits will not move the spear far where in the first grip they will fling it all over the place (simple lever physics tells us as much). Also, you should be wielding this from a lower position, with your back hand by your hip, and you forward hand out in front. This position will give you a lot of power from hip thrusts.
There are many variations on these two themes, but for the most part, its either high or low guard, and flipping your front hand palm up or down.
