to a fish

This really isn't very helpful. What would be more helpful would be to put the "fish" on a range of hands for his action preflop.

Once you have a hand range for this move by this player, then you can enter the range into PokerStove at home. Run that hand against AK. Once you know your hand equity, then calculate the pot odds of callling. If the pot odds are paying more than the risk you take according to the equity calculation, then call. If not, then fold. It's really just an EV calculation.

For example, if you have 3:2 pot odds (1.5:1) to call an all-in preflop with AK, and you have 45% (1.22:1) equity against his range, then call. You are marginally positive EV versus his range.

But, if he's over eager with his push preflop and there wasn't anything in the pot already except the blinds, then you would only have 1:1 pot odds after the rake. So, now you should fold with your 45% equity because it's -EV.

In each case, it's really just a question of equity vs pot odds.

At the table you obviously don't have PokerStove. So, run some examples at home until you know the equity against various forms of "fish" that you describe. Then calculate the pot odds and make a decision based on your estimated expected value.
