You're not really "trapping" by flatting with AK if V has a super wide range. You're only letting him realize his equity with junk. He's not making much of a mistake by putting in 3bb as a 30% dog, with initiative and position. If you do make TPTK, since he's stealing so frequently, most of his range is going to be crap and you get no value anyway.
Make it 50 pre.
