Here is my argument for not limping with AA UTG:
PokerStars No-Limit Hold'em Tourney, Big Blind is t200 (9 handed)
FTR converter on zerodivide.cx
MP1 (t16848)
MP2 (t10295)
MP3 (t9750)
CO (t5400)
Button (t8650)
SB (t16090)
BB (t27209)
Hero (t18813)
UTG+1 (t13244)
Preflop: Hero is UTG with A[img]/images/graemlins/club.gif[/img], A[img]/images/graemlins/heart.gif[/img].
<font color="#CC3333">Hero raises to t600</font>, UTG+1 calls t600, <font color="#666666">
2 folds</font>, MP3 calls t600, <font color="#666666">
1 fold</font>, Button calls t600, SB calls t500, <font color="#CC3333">BB raises to t2600</font>, <font color="#CC3333">Hero raises to t18813</font>, UTG+1 folds, MP3 folds, Button folds, SB folds, BB calls t16213.
Flop: (t40026) 8[img]/images/graemlins/spade.gif[/img], J[img]/images/graemlins/heart.gif[/img], 8[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
Turn: (t40026) Q[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
River: (t40026) 7[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>
Final Pot: t40026
BB has Kd Kc (two pair, kings and eights).
Hero has Ac Ah (two pair, aces and eights).
Outcome: Hero wins t40026.
