I'll add my 2 cents.

Now that you know position means you're the last to act. Here's why it matters.

When you have Position, then you have More Information than anyone else at the table. You've seen what others are going to do (bet, check or raise, or fold to a previous bet) and you can infer the strength of their cards based on that.

Then you get to decide what you're going to do. If it's bet and raised before it gets to you then you need really great cards to stay in. If everyone checks to you, then you might be able to assume they are weak and bet to steal (or take the hand) or check to get a free card to improve your hand.

You can play slightly poorer cards if you have position, because you aren't acting "in the dark" (i.e. without information). BUT, and this is important, you have to act on the information you get. Don't ignore it.

Advanced poker is a game of INFORMATION. Getting it, giving it, giving false information, etc. How people bet and from what position they do it gives you information. How they played previous hands is information you can use. I just called a guy All In in a 3 table $30 tournament. I had trip 9's. I have pocket 9's and call preflop (because I'm out of position - Position matters). The board flops a 9 and 2 clubs. I bet strong, he calls. The river is a 3rd club. I bet strong, he goes AI. I call and win the hand. HOW DID I KNOW HE WAS BLUFFING? I had noticed over the course of the game that when he hesitates for a while before doing an agressive act (like betting or raising) that he had a monster hand. But when he DIDN'T hesitate before an agressive move, that he was bluffing or had 2nd best hand (like top pair with a bad kicker).

Another way to get information is to throw out a bet. Here you're Buying information. Preflop you have whatever (it doesn't matter) and the flop misses you. But you think it missed the other guy too. You're in early position. You throw out a bet and see what comes back - a fold, call or raise. A fold is good, a raise is good too! you now have information. A call gives less information.

INFORMATION = MONEY. Position = More information
