KQ in CO $.50/$1

[RaiNz]

I had been sitting at this table for about 1 hour. UTG is a total fish that I have played with many times. He is capable of calling down w/ any pair. SB was weak/tight, and had never raised preflop. I was trying to isolate UTG. Would you raise this preflop? Advice on all streets appreciated.
