Easy Fold?

[Lurshy]

Why the check on such a favorable flop (if not to look for a check raise)?

Without hitting a set, that board is about as good as it gets. Would opponent overplay A4-6 (or call the pf raise with those hands?)? Can't see him overbetting a set. 77,99, 10 10, weaker pair possible. I think two overs unlikely, but possible.

If you think he overplays weak hands for protection call. If you think he over-bets solid hands fold. But next time make an opening bet, to see where you stand.
