I don't have time to read all of Erpel's posts, but why would you bet for information against a maniac?

Given the read, it seems that he will still be pushing a balanced range if you bet 5$ on the river, so you aren't really betting for info... Instead, he could call his small/mid flushes and beat you, and jam his missed straight/+ pair combos and his random bigger flushes.

Having said that, this must be either C/C or C/F.

What type of bet sizing are we C/C here with? Is a jam more likely to be a bluff vs a maniac?
