I agree with daviddem and would probably 3-bet pre for value/protection, but I think your line, flatting to include the fish, is just as valid.

Betting the flop is good even tho it's super dry. Not so much worried about giving a free card as missing a street of value.

Turn looks fine. You could bet a tad more, like 4, because now the board is drawy.

I'd probably bet 7 on the river but whatever they'll call of course. The exact sizing is kinduva personal preference.

Overall, it looks fine. Well played.
