Hi,
Flop: If board were JT6 I would not mind a raise here. He looks fishy over a low sample so I think you should have actually 3betted him preflop. This board is a little too coordinated, we lose to Q9/97/T8/JT and sets here so I prefer calling
Turn: I would raise the Turn now, I think the pairing card helps us a lot and besides there are so many draws now.
River: Half pot is fine here
Thanks.
