AK vs a reraise (concept)

[Josh.]

i'm not quite sure how to handle getting reraised when i'm holding AK. part of me feels like i can't fold such a powerful equity hand, but the other realizes that i'll flop a pair 1/3 of the time, and when i do it's unlikely that more than a flop c-bet will go into the pot unless i'm behind.

standard example (we'll assume 5/10 NL with 1000 stacks for simplicity):

we raise to 35 with AKo, SB (21/15 good TAG) makes it 115, BB folds, and we're being offered 2-1 immediate odds

what's the standard play here? if you choose to call or 4-bet, what's the plan postflop?

how does the situation change if:
<ul type="square">[*]we have AKs rather than AKo?[*]the SB is laggier?[*]we are 3-bet by the button?[*]we are UTG rather than the CO?[*]we opened from the SB?[/list]
i obviously know the broad answer to these, but i'm looking for more detailed answers on how to handle these situations.

thanks
