Hey!
Pre flop I would raise a bit bigger about 1200-1350.
As played, it's a really wet board, i'd be raising a bit bigger on the flop, the pot is 2.3k?
Would make it about 1500 and get value from a lot of worse. I expect he's calling the vast majority of the time.
On the turn, he doesn't have many 7's here at all and we have the back up of the nut D draw, betting this for sure.
When he re-raises you OTT, it's either going to be a flush or a boat or quads, this is hardly ever going to be a bluff.
Think we still have to call though, 2 see what he does on the river.
When the

comes in and he bets the river, We have

,

on the board. A lot of his flushes i'd expect to have KdQd etc. He still fires out on the river, which I don't expect him to do with a turned flush. The way it's played out it looks more like a flopped set as opposed to turned flush.
