NL50: Flush draw backed into TPGK

[bdon22]

No reads. Cake poker.

Turn call is 100% standard. The problem is when I river TPGK and he gives me 2:1 odds. It feels like I'm beat but I don't know by what - 87 for the double gutter, 44, 66, and TT are the only things I can put him on. Maybe a busted draw? I doubt he's bluffing since his river bet looks like it's for value.

Call and make a note for next time?
Fold because turn minraises are the nuts?

Btw has anyone else noticed that the 1/2 POT button is almost never used as a bluff?

He called flop and min-raised turn... you know you're way behind here and need your flush to win (thankfully he gave you such wonderful odds).

Riv, missed your club, fold.
