What's your typical pre-flop line with AK facing a min-raise behind?

[jedinite]

Context, if it matters much: Party large-field MTT, $11 - $55 buyin range.

You're halfway through the ~2000 person field and are sitting about double average chips with ~T3000.

You're in EP with AKo and make a standard 3x BB raise to T150.

You're min-raised behind to T300. The min-raiser has you covered by a few hundred chips. You have no reads, he just jumped to your table.

No callers, back to you. T525 in the pot, T150 to call.

What's your standard line? Call and play your standard post-flop OOP with AKo, or raise now to try to better define your hand?

I feel this is an area I can improve, and am curious to hear some thoughts from the forum...
