A villain this passive is either bluffing huge here on the river or hit the flush...I guess this is where a better postflop read comes in. He's only folded 3/9 flop bets, but is rarely aggressive on the flop for what it's worth.

If you haven't seen him get tricky fold, you have bottem set and both straight and flush draws came in.

fold river and remember to hit the 6s next time instead.

Sucks but easy fold.

Sorry guys, I feel like I've been posting a lot of fairly obvious hands lately it's just...I haven't really grinded FR for very long and am now starting to question every aspect of my play.

Good to hear I'm not going crazy here...this is a std fold for me.
