Attention !
Counting systems (HI-Lo, Wong Halves etc) are not meant to only guide your bets size. To reinforce profitability, you must not play with fixed basic strategy for every hand. Instead, your playing style must be based on the count. The counting system you use or its true count must influence:
Basic strategy deviation
Bet sizing.
Deviation strategies are the rule-breaks from basic strategy that you make when the count says the deck is unusually rich or poor. Instead of always following the same hit/stand/double/split chart. To access full mathematical optimization & assistance including exact betting amounts & split / hit decisions, request the blackjack deck dependent system which accounts for all value distribution and exploits the informational limits unlike pre-existing counting systems.

About Wong Halves performance
Betting Correlation (BC): 0.99
Wong Halves has an extremely high betting correlation. This means the card values closely match the real effect of removing cards from the deck. As a result, the system predicts profitable betting situations very accurately. A BC of 0.99 is among the highest of any counting system, making it particularly effective in shoe games (6–8 decks).Playing Efficiency (PE): 0.56
Playing efficiency measures how well the system adapts playing decisions (hit, stand, double, split) when the deck composition changes. A PE of 0.56 is moderate compared with more advanced systems. While it still improves strategy decisions, Wong Halves prioritizes betting accuracy over playing adjustments.Insurance Correlation (IC): 0.72
Insurance correlation measures how accurately the system predicts when an insurance bet is profitable. With a value of 0.72, Wong Halves performs solidly, though not at the level of specialized insurance-focused counts.Strategy Type: Balanced
Being a balanced count means the positive and negative tag values cancel out over a full deck. Because of this, players must calculate a true count (running count divided by remaining decks) to determine betting advantages.Level III Complexity
Level III indicates that the system assigns several different values to cards, including fractional values, increasing theoretical accuracy but also making it harder to execute in real play.Ace-Reckoned: Yes
Aces are included directly in the count, so no separate side count of aces is required.Ease of Use: 2.5 / 5
Due to fractional card values and true-count conversion, Wong Halves is more complex than beginner systems like Hi-Lo, but still manageable with practice.
