SSSSSPPPPPEEEEEWWWW

[evanski]

10-20NL. Ive had a bad 24 hours and Im in no mood for making tough laydowns, or even moderately easy ones (as I think this is).

5 handed. KJo in the BB. UTG minraises, called by button, SB, and me.

Flop: K 9 4, two of some suit I dont have.
SB leads for 75, I call, UTG folds, button calls.

Turn: offsuit J
SB checks, I pot it at ~350, button makes it 800, SB folds. I dont fold......Thoughts?
