I think now that turn should have been a raise as well so he would not even think to bluff on the river. What sizing would you choose and why?

Sometimes fish cause troubles)

I would personal isolate 3x and 1 bb per limper, but if you have the feeling most players will call still too wide if you raise this amount of chips this fine as well.

As played I would most likely raise bigger on the flop. If you raise 14bb or so you get most likely even more value of his draws and then you can shove most turns as well if the turn is a blank.

The turn would be tricky as played, but I think you can still shove on his 4bb bet. I expect he has to often a flush draw here.

The river is for me a clear fold with the flush draw that arrived here.

You could adjust your bet sizes a bit and raise that turn too. River is a fold as played.

yep, raise 14-15 bb OTF and shove the turn coz the adjusted pot would have been 50bb and would be left 25 bb if we raised at least half the pot which pretty much ties us to the pot, right?

If we raise the flop 15bb the villain would have 50bb left in a pot of almost 50bb as well and if he would lead the turn small you would shove for less than a pot size bet.
