Baby Ace ITM Hand . . .

[EasilyFound]

$11 SNG. This player had been miniraising throughout once the table shrank to 4 and 5 players and whenever he was first to enter the pot. Three of those hands went to showdown---he always called an all-in whenever someone pushed against him---and those three times he showed: A9, AQ, and AK. So I suspect here he had some kind of hand. Is it correct to play A7 here or muck it?
