Stanford Wong connected blackjack strategy with game selection. Writing under a pen name, John Ferguson published rule-specific analysis and helped popularize back-counting. His work explains why choosing when to play matters alongside choosing how to play.
From John Ferguson to Stanford Wong
John Ferguson was born in 1943 and grew up with an affinity for puzzles and mathematics. As a child, Ferguson would spend hours trying to figure out the solutions to very complex problems. This knowledge served him well in adulthood. Adopting the pseudonym of Stanford Wong, John Ferguson became one of the foremost authorities on the game of blackjack.
In Rick Swogger’s published interview, Ferguson said he was introduced to analyzing blackjack at about age 10. He computed how to play hands against different dealer upcards and later checked his calculations against Edward O. Thorp’s Beat The Dealer. He began casino play after reaching the legal age of 21.
He later developed tables for rule variations that Thorp’s book did not cover for his purposes, including hit-soft-17 games, surrender and restrictions on doubling after splits. In the interview, Wong explains how those calculations and written answers to learners’ questions grew into a book.
Ferguson published Professional Blackjack in 1975 under the name Stanford Wong. The book was revised and expanded multiple times, and the Blackjack Hall of Fame credits it with popularizing a table-entry technique that became known as “wonging.”
Ferguson published Professional Blackjack under a pen name while playing in casinos under his legal name. In a first-person interview, he said he did not want everyone at the casinos to know that he was the book’s author. The stated motive was to separate his casino identity from his authorship while he was still playing.
Wong said that Denny Draper, a friend in Stanford University’s PhD program, proposed the name. Wong liked complicated first names and simple last names and thought the result had an academic sound and an “Oriental” mystique. His explanation connects the name to a suggestion from a fellow student and the image he wanted for his writing.
Wong’s writing popularized a table-entry technique that became known as “wonging”: observing a blackjack game without betting, entering when the count becomes favorable and leaving or reducing action when conditions deteriorate. The term remains standard in blackjack literature, but whether the technique is practical depends on table rules, penetration and restrictions on mid-shoe entry.
Writing as Stanford Wong, Ferguson published analyses of blackjack and other gambling games and established Pi Yee Press. His work emphasized adapting analysis to changing rules and playing conditions.
Pi Yee Press published Wong’s work and books by other gambling authors. Wong also wrote about sports betting, craps, horse racing and video poker, applying a mathematical approach across different games.
Stanford Wong’s documented contributions include publishing blackjack analysis, adapting strategy to different rules and popularizing the table-entry technique now called “wonging.” He was nominated in 2002 for the Hall of Fame’s inaugural cohort, and the seven original inductees were announced after final voting at the January 2003 Blackjack Ball. The Hall of Fame biography emphasizes the influence of his book and table-entry method.
Wong said in a published interview that he started BJ21.com in 1996 after message-board software became available. He described the site as a place for blackjack players to exchange information through free and membership message boards.
In Wong on Dice (2005), Wong examined whether controlled dice throwing could affect craps results. The claim has remained controversial and has not received the broad acceptance of his blackjack analysis; readers should not treat it as a guaranteed casino edge.
His published legacy includes Professional Blackjack, the popularization of “wonging,” and books and newsletters aimed at serious players. Visit BJ21.com.
Back-counting is more than raising a bet
Back-counting means observing the cards without placing a wager, then entering if the chosen strategy’s conditions are met and the game permits entry. A player who stays seated and changes stakes throughout a shoe is varying bets, but is not necessarily back-counting. Observing from the start of a fresh shoe gives the counter information that arriving halfway through an unknown shoe does not provide.
Whether entry is worthwhile depends on more than a positive number. Match the counting system, true-count convention, rules and decision thresholds. Check whether mid-shoe entry is permitted and whether the minimum stake fits the bankroll. A favorable estimate does not remove the chance of losing the next hand, several large wagers or the whole session. Read the back-counting guide for a fuller explanation of observation and entry.
A hypothetical comparison: played rounds versus elapsed time
Suppose an observer spends an hour at a game but enters for only 20 rounds, wagering $25 initially on each round. Assume, solely for this illustration, a 1% average player advantage on those wagers under a fully specified strategy. The initial action is 20 × $25 = $500, and expected profit is $500 × 0.01 = $5 before costs.
| Quantity | Illustrative value | What it means |
|---|---|---|
| Played rounds | 20 | Rounds with an initial wager |
| Initial wager per round | $25 | One playing position per round |
| Initial wagering total | $500 | Repeated action, not bankroll |
| Expected profit before costs | $5 | An average, not a guaranteed result |
Multiplying $0.25 expected profit per played round by 100 rounds would give $25, but the observer did not play 100 rounds in that hour. Waiting, unavailable seats and entry restrictions can reduce opportunities. The assumed 1% is not a standard advantage supplied by Wong’s name or by every positive count. If expectation is measured against initial wagers, the model must already account for permitted doubles and splits; adding their stakes again changes the denominator.
Actual results can vary far more than this small expected profit. Travel and other expenses reduce a theoretical return, and a short winning session cannot show that the assumed edge is correct. This is why strategy tables, game access, wagering risk and time must be considered together.
