They recommend to cap the betting with As and Ks as they generate

AA vs KK became a normal thing, I no longer re-raise with KK and go on the defense until I see that Ks are generating any profits. In fact, for some unknown reason, in 5 weeks, I have lost 90% of what Ks have earned over the last 4 months. It seemed every time I held KK, and raised preflop, only 2 things would happen, no callers, or a re-raiser holding AA. In one session, in less then 20 minutes, I held KK and lost to AA twice, to same opponent. At a 10-person table, the probability is 4.41% or 23:1, the reason it seems to happen a lot is the fact that we play a lot of hands online, it's much quicker then BM casinos, so we see it happen often.
