First ever trip to Casino After read Professional Black

I walked in to the Casino not so bothered about an act, I wanted see if I could count the cards and see does this system work. I had trouble to start with and kept getting mixed up. However as the game progressed I got better and I finished up 20 pounds up. I was delighted!I was using the Hi Lo technique. I started off with 30 pounds invested in chips, then I finished with 50 pounds.

I am hoping it was not begginers luck !
