Sorry about the lack of details...
I only had 13 hands with this player. From those few hands, player is 38/9. Haven't seen a single hand of his.
Going back over the other hands he played before this, and from his VPIP/PFR ratio, I don't think he's bluffing
much since he's basically passive.
I guess his range certainly has low/mid pocket pairs and suited connectors. Ax and Jx for sure. So he could easily have a pair of Js, flopped a set, or has a flush draw. Lots of hands that could beat me.
But that's my off-the-cuff guesses. I don't think that I know well how to assign a range (beyond looking at the VPIP/PFR and figuring out based on Poker Stove which cards tend to match those numbers). Equally iffy on how to calculate equity. Pretty much, with this flop, unless I catch one of the two remaining 9s (and a 9 of diamond wouldn't be a good card for me) I'm pretty much always behind everything but a bluff.
