I think you played the hand fine. I would figure there was a draw out there...but you got your money in while you were still good. You were most likely ahead of all their ranges on the flop as most of them would call your bet with TP (as happened here). Sucks that he hit the 8...twas a monster pot. Good job on reaching 5NL! It gets a bit (a TEENY bit) tighter up there...but you should do just fine. Remember to value bet throughout and beware fancy play. That's what got me stuck in 5NL for an extended amount of time. Play aggressively (within reason). Also, learn to start tables (if you hadn't already done so). I took Spenda's advice on this and it has gone really well thus far. Good luck!
