what hands are you targeting otr? is half pot the most you can get from 2p+? Your turn sizing is really small, you will get very little value from your value hands. I would go 4x otf as well, when you have good draw and v is likely to fold a bit more to slightly bigger sizing you should go for bigger, at least up to the point where 3 barrels = stack, because of how equity math works.
It’s going to be very difficult to get 170bb in a non 3bet pot. I think it’s fine, you won’t hit river often so making your 2 barrels cheaper is good.
Only option for me is whether to bomb river, trying to look like missed flush. It’s quite a risk though as you don’t want to risk missing out on that juicy river bet.
I would mark this villain and bomb it next time. He looks like a non believer who will look you up!
