Why am I playing Party 3/6?

[AJo Go All In]

Limper UTG. Folded to me in the cutoff. I raise with AQo. Cold-caller on the button. SB 3-bets. UTG now limp-4-bets. I think for a second and fold. Button thinks and folds. SB calls.

All streets are checked with a K-high board and they split the pot with AJo unimproved.

because if you play with people who will:

1. 3 bet AJo from the SB and...
2. Limp cap AJo from UTG

You make $
