How Position Affects Play

To show how differently you have to play in first and last positions, let's say I'm dealt



in no-limit hold 'em (where position remains fixed throughout the hand). If the opponent on my left raised a moderate amount and got three calls, I would also call as long as most of the players had a decent amount of money in front of them. Were I to flop three 6s (the odds against it are about 8-to-1), I'd anticipate winning a big pot. However, were the player on my right to raise the same amount, I'd have to fold my pair of 6s even if I thought there would be some calls but no raises behind me.
My bad position is what makes the difference. It changes things enough on future rounds to turn a call into a fold. If I were to flop three 6s in last position, that 6 on board would look pretty innocuous. The original bettor would probably bet again, maybe get called, and then I could put in a big raise - or perhaps slowplay and wait to raise on fourth street. However, if the bettor were to my right, I couldn't immediately raise with three 6s and hope to be called by players behind me whether on the flop or on fourth street. Thus, when I'm directly behind the bettor, my implied odds are reduced so much that it's not worth calling that bettor's first raise before the flop.
