Early life: mathematics in Teaneck

Sklansky was born on December 22, 1947, in Teaneck, New Jersey. His father, Irving Sklansky, was a math professor at Columbia University, and from his preteen years David solved math problems and logic puzzles his father gave him almost every day. He enrolled as an undergraduate at the University of Pennsylvania’s Wharton School, left after a year in 1967 and worked briefly as an actuary before turning to poker and other forms of gambling. ^[3]

Beginning in poker: the Las Vegas of the 1970s

He arrived on the Las Vegas scene in the 1970s, when, according to The New York Times obituary republished by The Boston Globe, high-stakes poker relied largely on instinct rather than analysis. His longtime publisher and co-author Mason Malmuth described it as “more of a hustler-type game”. ^[3] Card Player wrote that in Las Vegas he quickly established himself as a winning poker player, blackjack card counter and sports bettor. ^[4]

Sklansky told PokerNews that the older players accepted him quickly because they often made proposition bets on which hand was better, and he could settle those questions “with pencil and paper”. ^[1] Chad Holloway, who interviewed him for PokerNews, summed him up as “the first nerd to enter poker”. ^[3]

The Theory of Poker and his ideas

The Theory of Poker was first published in 1978 as Sklansky on Poker Theory. According to the Globe obituary, it quantified concepts such as expected value (what a play is expected to win or lose on average), implied odds (the chance of winning more in later betting rounds) and reverse implied odds (the chance of losing more in later rounds). Malmuth said the book had sold 340,000 copies. ^[3] Card Player called it the cornerstone of strategic thinking in the game. ^[4]

The Fundamental Theorem of Poker

In the book Sklansky set out what he called the Fundamental Theorem of Poker: “Every time you play a hand differently from the way you would have played it if you could see all your opponents’ cards, they gain; and every time you play your hand the same way you would have played it if you could see all their cards, they lose.” ^[3]

He illustrated the idea with a bet that loses: if your hand is worse than your opponent’s and he only calls, “you have not lost, you have gained”, because his correct play, had he known your cards, would have been to raise. The obituary adds that Sklansky also wrote that mathematics is only part of the game and must be combined with reading opponents’ hands, psychology and deception such as slow-playing. ^[3]

Super/System and his other books

Doyle Brunson recruited Sklansky to write the Seven-card Stud Hi-Lo Split chapter of his 1979 book How I Made Over $1,000,000 Playing Poker, later re-released as Super/System. ^[1] Sources give different totals for his output: The Boston Globe counts 19 books on poker and gambling, 17 of them for Malmuth’s Two Plus Two Publishing, a company that also created popular internet forums for serious players; PokerNews counts 18, and Card Player “nearly two dozen”. Malmuth put total sales at 1.5 million copies. ^[1][3][4]

Titles named by PokerNews include Hold’em Poker, Limit Hold’em for Advanced Players, Sklansky Talks Blackjack and DUCY? Exploits, Advice, and Ideas of the Renowned Strategist. His last book, Small Stakes No-Limit Hold’em, written with Mason Malmuth, came out in December 2023. ^[1] Card Player also notes a modern adaptation of The Theory of Poker for no-limit hold’em. ^[4] Sklansky told PokerNews that during the poker boom he had three books in Amazon’s top 100 at the same time. ^[1]

Greatest achievements at the table

Three WSOP titles in 1982 and 1983

At the 1982 World Series of Poker, Sklansky shared first place in Event #7, the $800 Mixed Doubles Limit Seven Card Stud, with partner Dani Kelly; the 44-entry event paid each of them $8,800. ^[6] He then won Event #12, $1,000 Limit Draw High, against 31 entries for $15,500. ^[7] That year the WSOP awarded gold watches instead of bracelets. ^[1] In 1983, with bracelets back, he won Event #11, $1,000 Limit Omaha, from 51 entries for $25,500, beating Perry Green heads-up. ^[8]

Hall of Fame

Sklansky was never inducted into the Poker Hall of Fame. PokerNews wrote that it was not something he aspired to, and quoted him saying, “I was offered the Hall of Fame twice.” ^[1] Card Player reported that he considered himself a longshot for induction because of his relationship with some of the voting members. ^[4]

In his own words

“In poker, if you’re better than anyone else, you make immediate money.” Quoted in Al Alvarez’s The Biggest Game in Town (1983), via PokerNews. ^[1]
“In most games, the bets you save are as important as the bets you win, because your real goal is to maximize your wins and minimize your losses.” From his writing, quoted in the Boston Globe obituary. ^[3]
“Ideally, you want the pots you win to be as big as possible and the pots you lose to contain nothing more than your ante.” Same source. ^[3]
“I could tell them with pencil and paper which is better. So, I was accepted fairly quickly because they knew it was a big thing.” On the Las Vegas players of the 1970s, PokerNews. ^[1]

After his death, Mike McDonald wrote that Sklansky’s “books and forum were among the biggest influences on me and so many others getting into poker”. ^[4]
