The only reason I thought about raising the flop was CO was so bad that I was probably ahead of him in both directions. If I could have raised and gotten HU with him I would have but with the size of the pot and the amount of players I though that was unlikely.
The most amusing part of this hand was the results. I don't think anyone was surprised when SB turned over the str8 but CO and I chopped the low and I made a little bit of money on the hand. I'll bet nobody expected me to 1/4!
