AA on a pretty dry looking board facing turn decision

[KnutderIkeaElch]

Hey guys, its me again. I guess I am the guy who looses most in my entire database (maybe im the worst player???)

Party Poker No-Limit Hold'em, $0.50 BB (6 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: 2+2 Forums)

CO ($113.97)
Hero ($65.90)
SB ($48.40)
BB ($52.35)
UTG ($24.92)
MP ($45.70)

Preflop: Hero is Button with A[img]/images/graemlins/diamond.gif[/img], A[img]/images/graemlins/spade.gif[/img].
<font color="#666666">1 fold</font>, MP calls $0.50, <font color="#666666">1 fold</font>, <font color="#CC3333">Hero raises to $2.5</font>, <font color="#666666">1 fold</font>, BB calls $2, MP folds.

Flop: ($5.75) 6[img]/images/graemlins/club.gif[/img], T[img]/images/graemlins/spade.gif[/img], K[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
BB checks, <font color="#CC3333">Hero bets $4</font>, BB calls $4.

Villian has 30/6/2 so pretty loose passive

Turn: ($13.75) 5[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
BB checks, <font color="#CC3333">Hero bets $10</font>, <font color="#CC3333">BB raises to $21</font>, <font color="blue"> Hero thinks a bit and pushes all in</font>

He minraised me there, on minraises i feel so lost all time. I really cant get what it means, what a villian thinks when he minraises.

Is this spew/good/borderline?
Whats your line here
Comments on all streets appreciated

thanks Andi
