To new international BJ players
I was playing a good game at a casino abroad who knew little about card countings. I played its Hold'm table in the morning when an American CC sat down who just arrived town and waited for his hotel room. He started bragging about he was on a "super short term investment trip" and was just been barred from Cairo casinos playing BJ. Some players asked about his skills and he started explaining about CC and trackings in front of the poker dealer who dealt BJ also.
Please don't expose yourself before finding out whether the casinos' games were good or not and even if you thought the casinos' games were not good, you might be wrong and spoiled the fun for other APs who knew better.
