First of all WHY ARE YOU BOUGHT IN SHORT?? Second, you have an UTG limper and then a MP raise for 3x the BB, and you raise it to $8?? why??? You put 20% of your stack in preflop with KK against another 40 BB shortie and won't take it to the felt?? Raise that to $12 or so and the hand plays itself. If he has TT-QQ, you take his stack. If he has AA, you were crushed anyhow and if he has AK, and spikes the ace at least you made him make the mistake.
