Position = Information

You are admittedly just beginning to read people. As you get better at putting people on cards, you'll understand the true value of position. When your in a tournament, and the blinds are 1,000/2,000 it magnifies positional advantage. Not only can you steal preflop with marginal cards, but you can fish out weakness postflop and splatter scare chips all over that weakness.

Position gives you an option to utilize the delayed bluff steal as well. Someone bets out a draw on the flop ahead of you, you call his bet with next to nothing. When a blank turns, he checks to you or bets the same amount indicating weakness, and you go over the top of him. You can't do that without position. I use it all the time against timid limpers.
