Thoughts on every street appreciated. Interested in sizing thoughts. I don't have the HH, but the hand went down like this:

I have Ah6dAcKc. Very aggressive and somewhat unorthodox regular SB opens to 18, I pot to 54, SB calls. Pot is 108.

Flop is 8d 3s 5s. I bet 62 into 108 and SB calls. Pot is 232.

Turn is the 3h. SB checks I bet 144 and SB calls. Pot is 520.

River is the 2d and SB donks for around 350. Hero???

I'm interested in thoughts on my sizing choice on every street, Is everyone betting flop and turn? Thoughts on that are appreciated as well. I am obviously most interested in the river decision. Thanks!
