Hands that beat you: AA, 99, 88, AK, AQ, A9, A8, A2
Hands that you beat: other PPs, AT, A7-, could he really have KQ-?
Admittedly, I have not played 6-max much, but shoving here seems like it would fold most of the hands you beat, and almost none of the hands that beat you (exception AK and AQ, though as Richyl said above, maybe not), so I don't see the point... unless you think you can persuade him with this shove that you have hit a set/house and fold his 2-pair hand. Or is this way off?
Calling would be my preferred line here, although I would fully expect him to turn A8 and win...
And folding is always an option, although I think he would play KK ot AT in a very similar way...
