I don't understand position. Please help.

[Ironic]

Hello all. I do not understand the importance of position. For instance. Suppose I am on the button and I raise preflop and get three callers. The flop comes, the others check and then I raise. Surely I letting myself open to people who hit big on the flop and check raise since they know I raised pre-flop and see me as the agressor?

Also I just don't generally get the concept of position. Can some people give me concrete examples of how position helps me.

Thanks all. [img]/images/graemlins/smile.gif[/img]
