Preflop is a bit eh, flatting entices BB to come along and this hand doesn't play great multiway aside from nut spades.

Flop doesn't favour your SB flat vs. BTN open range so no need to get colourful with some donks or x/r, check call looks fine.

Turn is interesting and I think a good donk, this card hits your flop x/c range pretty well so semi-bluffing aggressively here looks fine. When villain calls here he often has diamonds that we don't block, or some overpair+ gutter combo and the occasional straight like A5xx, assuming he also just rips it with 56 considering the wet board texture.

River I prefer a check call, you can sometimes get a bluff out of missed diamonds, although in my experience villain will likely check back a tonne of hands on this river, including some 2p type hands so you can also make an argument for leading small, betting with your sizing doesn't look good to me.
