BB mucked and WON $57.50 (+$28 NET)I absolutely hate this situation, and have to agree with Craig and Rodney that this is a spot I need to avoid in the future, by folding to the re-raise.  But having played it, I felt good about the fold there.  With the J on the board, the only hand I'm beating is AK and maybe 99 or 1010 if those are in his PF re-raising range.
Question: Does being in position make you more likely to call with the AQ?  Or is it an auto-fold to a PF re-raise to a non-laggy opponent?

 (a full house, Tens full of Kings) and WON $118.55 (+$57.90 NET)It's good to know I'm not the only one who gets stacked here.  I think the potential for draws killed me.  I was able to convince myself that there was a good enough chance that he had QJ or a flush draw that it was worth it to stick around.  The turn K helped finished me off.  Looking back, bells really should have gone off at the strange raise to $35.  Because I don't think that an OESD or FD does that.  That's the move of a made hand.  I think only 88, 1010, or K10 makes that move, and I think I could have gotten away at that point.

 7
 (two pair, Eights and Sevens) and WON $113.90 (+$55.70 NET)Ah, the world isn't all that bad.  I figured him for something like 7-6, 9-10, 8-9, and figured I was going down to a 5-6 or a lucky naked 5 regardless.  But I can't 
believe he made that call with K-8.
So during this session, I ran well for about an hour and a half, and then got absolutely hammered for about 30 minutes before I quit.  I lost 4 buy-ins during those 30 minutes.  Lost another big one (not posted) holding QQ on a J-9-7 board, where my opponent flopped the straight.  I made that big fuss about letting go of big pairs a little while back, but I still can't put it to any use.  Until I can actually learn from these mistakes instead of repeating them, I'll be floundering around at this level, probably for a while.  See you at the tables.
