This system is derived from the Omega II systems described in Bryce Carlson's superb book, "Blackjack for Blood" . The Omega II count system is a very good level-two true-count card counting system. This system is probably the easiest of all two-level count systems to learn, and performs a better than HighLow, especially in single deck games.
The database includes 14 index sets covering every permutation of single deck and multi-deck game with DAS, noDAS, h17 and s17 ( double after splits, dealer hits/stand on soft 17). Index sets for the Basic Omega II systems and Advanced Omega II system are included. Even a Surrender index table is including, which fully supports late surrender using the new secondary index feature in Blackjack Counter.
The documentation describes every table in detail, plus a single table is included comparing the parameters, expectation, and bankroll for each index set.
As an added bonus, this set includes the extra action tables in the Basic database... no need to buy both!
