Hi elvon, i don't consider myself an expert, but i will try to explain the idea of position as best i can.
i see the word position used in a couple of different circumstances;
1) to refer to where you are in relation to the blinds at the start of the hand ('early', 'middle' and 'late' positions)
2) to refer to where you are in relation to remaining active players later in the hand
(ie 'it got heads up and i had position on the guy', this means that only you and one other player are still in the hand,
and you get to act after him on every betting street to come)
sometimes people in these threads will use acronyms:
'IP' = In Position = they get to act AFTER the other guy(s)
'OOP' = Out Of Position = they have to act BEFORE the other guy(s)
IP is generally better, for lots of reasons, but the one i 'got' the easiest is that it's good because you get to see what the other guy does first, and so you have more information when making decisions than your opponent(s) and so are likely to make better decisions.
as to 1), you will see acronyms such as:
EP = early position
MP = middle position
LP = late position
at a ten-handed table
I would define them like this:
EP = first 3 players to act after the BB
MP = next 3 players
LP = last 2 players (aka 'cutoff' and 'button' seats)
others may disagree and define them slightly differently, some may define the last THREE seats to act as late, or define 1 more or less as early position, but i doubt you'll see massive differences (i hope, or maybe i need to start one of these threads for myself...
)
hope you find this helpful and not too confusingly written, never realised how much i could write about position before, and sorry if i repeat what others have said above, i'm a slow typist.
oh, and having read AKQJT's post, his description of relative position is excellent information, succinctly put, but without wanting to step on any toes, i think maybe you should concentrate on understanding absolute position first, before moving on to understanding relative position. speaking from personal experience, i like to learn things one bit at a time, and i think if i had tried to learn about both at the same time, i might have ended up more confused than when i started
