I had decisions like that especially online with limited time to think. If i was first or second or even third to act at a full table i think i fold 7s from the start but i think all in before the flop would be a good move although i dont think anyone online is folding AK to an all in that late in the tourn. Even though the blinds are getting big i'd rather wait for a chance where i was a big favorite rather than a small favorite. You lose some your chips but u avoid a close gamble and if the cards come u will win those back x3 and more when u double up. I say this now, but in your spot i would have prob been all in also and then wished i folded to avoided putting my chips at risk before the flop. I think a call and fold to the bet is prob the better move. Goodluck next time!
