Figured it would help me get accustomed to 6-max without losing a ton. I was wrong. Did I do anything wrong on the following hands....

25/50 cent blinds $15 is considered all-in

Hand 1: [Js] in BB vs a limp/re-raise. UTG is a maniac (73/24/50)
5 handed - UTG limps, Button limps, SB calls, I raise to $3, UTG re-raises to $5.50, Butto and SB fold. I can only bet $12 more to be all-in. Push, call, or fold.

Hand 2: [9h] in SB. BB is maniac (90/28/40 - previously all-in with Q5o and 22 both post flop unimproved), UTG is unknown.
5 handed - UTG raises to $1.50, I call, BB calls
[7h][6c] Pot $4.50
I check, BB bets $4.50, UTG is all-in for $13.50.
I know that BB is calling so there is $31.50 in the pot essentially and I need to call $13.50. Is this an easy call?

Hand 3: [Js] UTG. BB is 28/11/24. no read other than stats
I raise to $2 and only BB calls
[Jh][7s] Pot $4.25
BB checks, I bet $4, BB raises to $8
I can only bet another $9 total since I'm already in for $6. Under these circumstances I can't fold, can I? so I might as well push and put him in for another $5, right?

Playing 30BB deep TP is the nuts and you need to get AI.

Hand 1 get it in

Hand 2 fold PF, this is not the type of hand to play in capped games

Hand 3 get it in
