Poker Tracker?

[12AX7]

Hi Everyone,
I downloaded the Poker Tracker demo. It did 1000 hands and now won't let me look at the results any more. LOL!

So can someone enlighten me on exactly what Tracker provides that helps me make game time decisions?

For example, does it show me things like, "Opponent X waits until the turn to raise trips 47% of the time" and "Opponent Y raises AJo UTG 14%" etc.?

What do all these acryonyms like VPIP mean etc.?

I guess I need the full education. LOL!
