Sorry, I mistakenly posted the name! I meant to inquire of you if you had an opinion of "The Color Of Blackjack." I am just starting to play (count). I had immediate success using KO. At first I thought I was just extremely lucky! After 20 or 30 hours of play I was beginning to think this really works! During this trial period I became aware of the book The Color Of Blackjack (which morphed from KO)! I feel it would take me to the next level. I am respectfully asking for your opinion.
