AK Push , Call or Fold after 2 miniraises

[Crispy]

350 k gauranteed. Blinds are 400/800 and you are sitting with 7 k in chips. Average chips are 13k and big stack at the table sit s with 26k. Big stack has been raising almost every hand and finally got called down to show a 86s. Next hand you get AK.
He again miniraises to 1600 like he did when he showed 86s but now a somewhat tight player miniraises to make it 2400. Do you take your shot now? Or is the miniraise of the tight player just too suspicious? Is there a better spot to get ur money in when you might be a bigger favorite? As hero do you push, fold, or call?

The tight player is as aware of the big stack's tendencies as you are. I can see him doing this with AJ to feel the rest of the table for resistance. You're so short stacked, I really don't think you can pass this opportunity up.

You have less then 10x the BB, so call in out of the question.... So puss em in
