Spew?

UTG and UTG+1 were both terrible players. UTG played 80% of his cards and would bluff on every betting round with hands like J2o. He capped all streets with pocket 2's on an earlier hand and lost to top pair. +1 was a bit more solid playing only 50% of his hands and raising 20%.

Preflop: Hero is MP2 with K[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/heart.gif[/img]. CO posts a blind of $0.25.

I decided since I'm going to continue I may as well raise and hopefully give myself a better chance of winning should I hit an overcard. I thought my raise would possibly eliminate players. The board was somewhat connected and had 2 diamonds so I'm wondering if my flop play is spew?
