How to play AKs

I will show the turn later.

By the way, this is a 5.50 tournament.

With a lot of people in the hand and AK missing on the flop you need to muck or call a very small bet. You needed to push hard before the flop. For a $5 tourney I stick it all in. At worst it's a race.

after the minraise to you, pop it to 350-400. should narrow the players going to the flop.

with this many players to the flop, and you having missed, you've got to let it go for anything more than a tiny bet.

definitely raise preflop though. word on the street is AK is a strong hand.
