Can't fold unless you make a declaration before hand like negraneu - and "Hero fold" - you can still come back. But I always see negraneu call in this situation - you have too or be a foilder the resat of your life - which you aren't. I lost a $200 free roll this way - I just hoped my premium cards paired or the river/turned paired for a higher boat - I called then and lost but still think I should have called - $300k pot - oops.
