bet at least 3/4 of the pot in this heavy drawy flop Such a small weak bet on your part couldn't really deny any drawing odds though!!!!!!!! His preflop calling range should include AQ+ ,most of pocket pairs and some strong suited broadway cards.
i 'd call his reraise and reevaluate on the turn. If he made a huge bet on this turn, i would lay down my KK but if checked to, i'd check behind or move in depending on what type of villains i play with.
On the other hand, if you are willing to risk losing a lot and plan to pay him off, moving all-in on the flop was the best.
anyways, you should always have a plan in your head before betting out with good hands. Ask yourself this question: " am i willing to lose a lot in this hand?"
