It varies by position, I play 6 handed 1st in
UTG: ALLIN with 55-AA,AJ-AK
keep liberalizing the range until on the
Button: ALLIN with any anything decent (QJ, A4, k8 suited)
SB: ALLIN with all but the junk hands (I'd push with 7-9)
IF someone else pushes, from 1st three positions, I call with AQ-AK, 99-AA. BUT, vs. button ALLINS call with A7, KJ, 44-22. Vs. SB allins call with any ace, k8, QJ, any pair. I also call with aj,a10 vs. cutoff pushes.
