i play $25 UB. every once in awhile, i will be on a table where my continuation bets are getting zero respect. i tend to believe them the first 2 or 3 times, b/c ppl will occasionally fold on UB. but when it gets to be the 4th or 5th time, other players are noticing, and it starts getting in your head, you have to change tables. simple as that. i find that always clears my head.
if you have to stay at your table...i would say you have to tighten up. wait until you get your groove back. hopefully you can showdown a big hand and then ppl will start repsecting again.
