c/r flop. if you must lead out make it like $1. thats way too small

as played, all in on turn

Don't really like the 40% flop bet. We need to be betting more here.

Not a bad spot to c/r turn imo, Kd doesn't really change much and UTG looks like he has AK, AQ by his flop play (therefore he'll bet if checked to)

As played, all in. Now it def. looks like AK.

with 4 people in the hand, i'd just jam on the bet pot button every time it was my turn. if i have a monster hand in a situation that i wouldn't dare bluff, i'm not going to be real sophisticated in my approach.
