Villain is 92/29 54h.

P: std 3b
F: I have an overpair with a gs and bdfd. I think vs two villains overcalling I still have a flop cbet for value.
T: He donks halfpot. This seems to me like a desperate attempt to draw cheaply sided with some marginal sd value. I also block the nuts. I would assume he would be potting if he wanted max fold eq with a monster draw. I don't know how much do I benefit from shoving here?
R: pretty bricky card. I would have folded on an any connecting 4card str8 card but here I decided to bluffcatch.

1.What is your turn thought process?
2.Should we bluffcatch R?
