I never go all-in over a re-raiser in a cash game with AK just because I don't like my chances if I'm called. Especially if villain is laggy, because he just might call with TT, JJ, or QQ as often as KK or AA - all of which have me behind preflop.

Since I don't like pushing, I'd be inclined to fold to the $25 reraise. If I really thought villain was overplaying his hands and making too many continuation bets with 2nd pair, gutshots, or over cards, then I'd call the reraise preflop and then check/fold if I miss the flop, or check/raise significantly (up to all-in) if I hit TPTK (in which case I'd be screwed if my read was wrong and he really DID have AA or KK this time).
