3 player strategy with low Ms

[Secret Squirrel]

Live game 3 players remaining, payouts $1100, $700, $400.
Other two good players with calling ranges of most pairs, A8 and above,and KQ possibly.

Blinds 8,000/4,000

BB 120,000
SB 50,000
BTN 40,000

Hero on Button with A6.

1) I usually see this as an easy push but instead would it be more profitable to just push any two into the other short stack each rotation he is BB?

2) Also as getting called by better aces (and not getting called by worse hands probably)is it better to push two medium/high cards here as still likely to have two overs to pairs and unlikely to be dominated?

Basic questions but just want to make sure that I am on the right lines here.

Thanks
