TARGET. {RWC} (c1983) (Developed by Eddie Olsen and originally marketed by Jerry Patterson). Also called TARGET 21. TARGET stands for TAble Research, Grading and Evaluation Technique. This is the controversial table selection method that claims to be able to exploit shoe games (and single-deck games but to a lesser degree) because shuffles are non-random. This system claims that games with non-random shuffles tend to have biases that favor either the dealer or player and that these biases can last for several shoes or decks. An observant player is therefore told that he can increase his chances of winning by playing only at those tables that have evidence of current player winnings and by avoiding those tables that are dealer biased. The actual selection process is simplified to a set of table selection factors.   The TARGET system, as marketed by Jerry Patterson during the late 1980’s, also recommended variations to basic strategy under excessive dealer-breaking conditions and the use of progressive betting.   The TARGET system, as presented by Eddie Olsen during the 1990’s, was somewhat different in scope and methodology. Eddie Olsen placed a greater emphasis on card counting and did not completely agree with progressive betting methods.  TARGET players were taught that 70% of games are dealer biased, 13% are neutral, 10% are player breaking, 5% are player biased and only about 2% are dealer breaking. There is no scientific basis for this system and it is NOT recommended. See BIAS Barometer.

true count. (TC) Also called the true. Also called the count per deck. The running count (RC) adjusted for the number of cards or decks remaining to be played. This is typically expressed as:


TC = RC / N

Where N = Number of remaining decks

The true count is a much more important indicator of the a player’s advantage than is the running count. An increase of one true count unit is often estimated to be worth about +0.5% overall to the player. As an example, if there were 2 decks left in a 6 deck game and the running count was 5 the true count would be only 2.5. Card counters using a balanced count need to be able to figure the true count in order to accurately implement point count play variations and to properly size their bets.
