How do you maximize this crap??

[hotmark777]

The short stack all in obviously has crap, initial raiser obviously high pair most probably aa/kk what is my move to maximize value? I think min raise is too obvious, and all in might scare away. Opponent said i should have flat called but what is my play on river? small bet? That would have definitively worked but i dont get all his stack which is objective...
