I feel like i have played enough poker now that i no longer consider myself a beginner. However, K-K is a hand that tends to get me into a lot of tough spots, such as the following. What i would like to know is, against a player whom i have no reads on, what do i do with this hand? Should i pop it for one more raise, and fold if he pushes? I should also mention that the raiser did drop a $100 pot 5 hands before this one.
