Blackjack System - Version 2.1 The winning MENTAL blackjack system is founded on Fundamental Formula of Gambling and Martingale, Fibonacci progressions; no counting cards required. Software and PDF included.I founded the winning MENTAL blackjack system on the Fundamental Formula of Gambling (FFG). The full system, as used with a notebook, keeps track of several streaks: Win (W), Loss (L), Dealer Bust (DB), Player Bust (PB), Dealer Blackjack (DJ), Player BJ (PJ). In my trimmed down version, without the notebook, I only keep track of two streaks: Win (W+), Loss (L-). This is a mental gambling system - the records are kept in my memory.My count always starts at: 0 - 0. I say mentally zero - zero.1) The first number represents my consecutive losses;2) The second number represents my consecutive skips without two or more consecutive wins.
