Three All Ins

[HoldingFolding]

My question is actually largely irrelevant to this hand but it got me thinking.

Party Poker No-Limit Hold'em Tourney, Big Blind is t400 (10 handed)

Final Pot: t7477

In this example MP1 was on a pseudo steal and pot committed given the size of the stacks, but if he was in a calling position would you ever really want to be the 3rd all in caller with the typical all in hands (mid/high pocket pair A picture) excluding AA &amp; KK and similar stack size?

If you assume (pretty big assumption granted) that one of your opponents has a mid pocket pair and the other has aceface:
If also have a pocket pair:

Qs Ad 498866 36.39 868106 63.33 3782 0.28 0.365

If you also have an Aceface
9c 9d 623285 45.47 743596 54.25 3873 0.28 0.456
Jc Ah 272190 19.86 1064886 77.69 33678 2.46 0.210
Qs Ad 441601 32.22 895475 65.33 33678 2.46 0.334

Which would say to me that with three fairly balanced stacks you should only be the 3rd person going all in when you have AA, KK or QQ?

This never got any replies, but it continues to intrigue me. Just how much should you tighten up if you are to be the 3rd person going all in?

I think MP1's play in this hand is fine.

If I were the button, I would not call all-in here without AA/KK/QQ. He has 0 folding equity since one player is already all-in and it's likely the pot will be at least 3 or 4 way. With over 6 BB's he could wait for a better spot to push, unless he has a premium hand.
