Hellooooo guys!
I'm from Slovakia and I have been counting cards for some time, but I still have some insecurities about certain things in the game. Last night I saw a big player come to our local casino and I almost immediately found out that she is a card counter (backcounting). She played with table minimum at TC 0 or negative - ONLY ONE BOX and played maximum bet while the TC was anything above TC +1 (included) ON SEVEN BOXES. Minimum: 3 €, Maximum: 200 €. Her bankroll was 10 000€. She played perfectly. So much heeaaaaaat.

My question is: Is it a good strategy to open more boxes during positive TC?? Or how many is the best? I believed it doesn't make any difference if I play one box or 7 boxes with same bets. I just raise my bets. I only understand it is a good move (open all boxes) if you see the cut card coming soon and the TC is positive, because you want more cards to be dealt in this situation. Thank you for your opinions and answers!!! <3
