55: 1st hand of tourney, I fold AKo to 4.5BB raise

[Mr_Oog]

I would also call. I would expect AQs+ and JJ+.

High card hands: You are a large favorite here. Not just in terms of having AK vs his somewhat possibble AQ and AK, but due to position and the likelihood the flop will miss both of you.

Big pairs: You are a dog, but as long as you can play well post flop you should be ok. You have some room with 1000 chips, don't be afraid to play.

I expect to call or raise the flop (more likely raise) depending on his bet size. If he shuts down on the turn I will steal the pot from him unless I have a monster.
This will cost some chips, but is very likely to win you some chips as he will only continue with a good made hand.
