i hate the way i played this!

[umdpoker]

as a preface to this hand, i have been running very bad the last 3 days, and i am a little concerned that i am becoming even more weak-tight than usual. basically, any time i think something is close to neutral ev i fold now, instead of raise, or call. please comment on all streets. also, the guy who called my preflop raise had previously called $4 preflop with k8s, and won that hand.
