common situation that i f'ed up royally

[RikaKazak]

Pfreflop I disagree, but I know many LAG's at 1K that limp called my pfr with J8s or A5s (lolotrickedu used to do it to me all the time, if say 2 limpers and I bumped in on the button)

As far as flop, I really doubt you're ahead. I like a ck/call on flop, then lead a safe turn, or ck again and let him keep bluffing his overs. Ck/raise I think you have to fold to a 3 bet, unless there is history. Leading on flop is "meh" imo, maybe lead, call, or lead fold, then evaluate on turn if you get there.
