I recently took up blackjack and have moved onto try out card counting with the +1/-1 point system. In the beginning, the casino I've played at had 5 and 6 deck shoes. I was winning most of the time. Now I noticed they've gone to 8 deck shoes and I've been losing most of the time. I'm wondering if it's the 8 decks (because advantage % goes down) of if it could be possible cheating or both? I've sat at a table and had them change dealers more often than usual. Should I move to another casino that doesn't use 8 decks????? Thanks for any advice.. Kar
