Villain has only been at the table for about 6 or 7 hands and has only played 1 hand so far. So no reads and meaningless stats. It was 8 handed up to a hand or two before this when a couple of players left.

The widest range I could think to put him on is JJ+, AKs, AKo(and that was being generous) and that gives me 42% equity and I need 46% to call so it seems a clear fold to me.

Am I playing too tight or is it reasonable to just fold this and wait for a better opportunity when I have more info on villain?
