Poker author and WSOP champion David Sklansky has passed away at the age of 78. 

Sklansky was born in Teaneck, New Jersey and he attended the University of Pennsylvania before dropping out to pursue work as an actuary. He would go on to become one of poker's most impactful authors

Among Sklansky's many books was the highly influential Theory of Poker, which gave household discussion to terms like expected value and implied odds. Other books, like NL Hold'em Theory and Practice, introduced ideas that are practiced well beyond poker, with Sklansky's six levels of thinking referenced as a strategic guide for contestants on reality shows like Survivor and Big Brother, along with their applications in the business world. 

Sklansky also won three WSOP titles over two years in the early 1980s, and he appeared on poker TV throughout the boom years of the early 2000s. His Hendon Mob profile sports $1.4 million in earnings from 1976-2017, with a gap before two final daily tournament cashes in the summer and winter of 2024.
