2/4 sh, two hands against the table maniac

[ShenTe]

Here two hands at the same table short after another.

1)
SB: only 8 hands, however he showed jack high hu and bottom pair against three opponents to the SD, he seems to call down with anything
BB: 62/21/2.71/26 hands

Flop: (6 SB) 5, 8, 5 [color=#0000FF](3 players)</font>

2)
In addition to the mentioned hand I foldet some other hands to the maniacs bets and raises so I assumed he thought I am very weak tight. After the flop in the following I was confident that I was ahead, but the turn card I disliked. However I wanted to go to the SD with this hand to stop him from bluffing and I also could have been ahead. Due to his aggression I decided to let him bet and make a call down for myself. Do you agree with my thoughts and my decision? Or would you have played the hand differently?
villain: same as the BB above

hand 1 i'd either cap the flop and call down from there or call down and raise a safe river (mainly worried about a 9 or 4).

hand 2 is whatever. you could also keep betting and call down after you get raised depending on what you think his level of craziness is. the way you played it is ok.

I would cap hand 1 on the flop and if SB is still in the hand I would probabaly fold to a bet from either of them on the turn.

If its heads up Im still tempted to fold if BB donks the turn after I have capped the flop but that decision is closer.
