i fold the turn in hand 1. Without a spade in your hand it is unlikely you have a lot of equity in the pot. You could be drawing to 2 outs vs a lot of hands. I would wait for a better spot to call down the maniac.
Hand 2 i would raise the flop. Too many cards you dont want to see on the turn.
The way you played it i probably bet the river because ace high is calling the river if he called the turn since there are so many busted draws you could have.
Hand 3. No way am i betting the river. There is a 4 straight on the board so it is unlikely he pays off with many worse hands.
You probably have to call the turn because 88 and 99 play the flop and turn just like villian played his hand. Of course he also plays many hands wwhich have you beat, TT+, this way.
