This is absolutely perfect imo. Probably for the wrong reasons, but whatever.
you could make it 3 on the turn - I think betting bigger is a mistake cos of stack sizes and reads. We want to keep his range as wide as possible while setting up a super easy river shove. What's the point in betting 1/2 pot and then 1/10 pot all-in otr?
However turn bet makes no sense if you don't know what to do on this river. (obviously jam)
