KK fold on A-high flop

[Ghazban]

Villains are both new to the table and don't appear in my PT database so I have no reads. Is this a standard fold? Headsup, I'll often raise a weak lead here but, with so many people in, I expect its more likely that the flop bettor has a hand he won't fold (set, AK, AQ, AT, etc.).

Easy fold, hes bet into the field UTG and theres still one guy behind you, I find it hard to believe someone doesn't have an A or is at least beating me here.

It just galls me to fold to these weenie weak leads. Unfortunately, I can't raise and I can't call [img]/images/graemlins/frown.gif[/img]
