You are in position only for 1 round of betting. If you go all in you did so in position. If you don't, you have the worst or second worst position at the table for the next 3 rounds of betting.
How often do you have a hand that you want to push with preflop? How often do you have a "push hand" but need to see the actions of players in front of before you push? The latter is the only case in which you have an advantage in the blinds. I'd really hope that is a very small percentage.
More often than not you are going to call, raise or fold. If you call or fold your position is now one of the worst at the table or you're out for the rest of the hand. If you raise and get called the same applies. If you raise and get reraised the second sentence of the previous paragraph applies.
Position, in a nutshell, is having the advantage of seeing the actions of the people ahead of you before you decide if you want to get involved in a hand.
Where's your advantage? In terms of position, if you are still in the hand after the flop, you have zero.
. I would have to agree you are in early position, because you act first after the flop. But you are in late position prior to the flop. I gotta look this up.. I'll be back.
