Thanks guys -- I appreciate the comments, even if it was a dumb one.
My hand clicked "check" on 7th before my brain could intervene. I was obviously good (against a pair of 3s with I think a 10 kicker, that probably wasn't worth a call at any point).
I go back and forth on raising vs. calling 3rd -- here, I had some fairly spazzy opponents (it was a very enjoyable table if not for repeatedly losing to 2-4 outers) that I didn't particularly want to go to war against with a 457. If I bricked 4th, I'd have much better spots. If I didn't, they'd play along with me anyway.
