David Sklansky is one of the most respected gambling theorists in the world, often called the "father of modern poker theory." He has authored more than a dozen books, including The Theory of Poker, which is considered a must-read for any serious player. Sklansky’s work goes far beyond poker — he has written about blackjack, sports betting, and general gambling mathematics. His insights teach players how to think in terms of expected value and probabilities, rather than relying on gut feelings. He has trained generations of gamblers to approach games with a disciplined, rational mindset, making him one of the most influential educators in the industry.
