Did I misplay every street?

[Yads]

There is not a chance in hell I'm folding KTo in the BB against a maniac's opening range. What's with the posts lately talking about making ridiculous folds PF in the BB?

As everyone said I'm going to war on the flop. Your pair is still vulnerable so get in as much money as you can now. I'd be more inclined to wait until the turn if I had a higher pair. River is tough, if you think he'll really 4 bet with worse then go ahead and 3 bet planning to call a 4th. If you'll be in a tough spot if he 4 bets then just call.
