Nice to see your river riase sizing is improving. This is a good river bet.

Turn, we can fold, but I don't hate the call. Just... when we get there, bet enough to make up for the marginal turn call. Which you do. It's pretty unlikely he has a flush considering the line he's taken, he seems to be trying to control the pot, which for an aggro fish is usually a strong indication he's weak and wants a cheap showdown. Sometimes he might turn up with a flush, we're calling if he jams so we just have to take it on the chin.

At the risk of being repetitive, don't be short stacked. Not sure why you persist in this strategy when you're playing against such bad players.
