Looks fine to me. You can also jam turn.

The half pot donk on the flop usually indicates a marginal hand or a draw of some sort.

You would get it in anyway.
So I'd prefer to jam turn instead.

I can't find many faults with your line here. SB calls in my player pool are like 66-JJ and suited aces and sometimes like KQs, QJs. That range connects fairly well with this board. Sure, if you know he has 8x or set, jamming turn is fine but there are hands in his range you don't want to lose to an over bet. Honestly, you don't want any hand to fold. You gave sets and flushes an unprofitable price on the turn to draw/fill up. Your turn bet gives 2:1 (33%) direct odds on, at best, a draw that hits 1 time in 5. His implied odds are terrible here with this stack depth. If anything, I can see betting/raising a little smaller but in a pool where calling is the biggest leak, I can't fault your play at all.

As I said above, I'm fine with the play here. Just a small point on the river play.

Often when the opponent donk shoves river for a very small amount (relative to pot), it means that the river improved their hand in some way. Think about it: they're probably not donking for fold equity for such a tiny amount. Instead, they see the river and their eyes light up, and they try to get their money in. Here, the donk shove could represent a boat (what else could it be? Is he really donk shoving trips on this board?)

In these cases, you can sometimes get away on the river. However, you would need a fairly good read on the opponent to make the fold because you're getting amazing pot odds.
