I played a casino where about half dealers flashed bottom cards of each piles during shufflings thus players know 8 to 12 cards and their locations after shuffling. The problem was how to cut accurately. I couldn't cut accurately on my first visit and cut mostly single picture card not caring much about the other flashed card and spreaded to 7 boxes catching the flashed picture card. I lost heavilly despise catching the card mostly. I realized on my later visit that the loss on small card off-set the big card thus I bet into negative off-the-top shoe (about minus 0.3%). The new strategy was cut more accurately and on Ace(s), 2 picture cards, or at least one picture card with an 8 or 9. The next problem is the not 24-hour table and crowded table. Anybody came across such table? Any suggestions?
