Biography & Poker Background

Born in Evanston, Illinois, and currently residing in Indianapolis, Indiana, Cynn attended Indiana University where he first developed his passion for the game. Before his breakout on the world stage, he was a regular in mid-to-high stakes cash games and tournaments across the Midwest and Southern California. His 2018 victory was the culmination of a grueling 10-day battle, ending in a record-breaking 442-hand final table and a marathon 199-hand heads-up match against Tony Miles. Known for his humility and calm demeanor, Cynn has used his platform to advocate for a balanced life, often speaking about the mental health challenges and isolation inherent in professional poker. He remains a key figure in the “post-boom” generation of champions who favor technical excellence over flashy table antics.

Play Style & Strategy

Cynn is celebrated for a “highly disciplined, methodical, and patient” play style. His strategy is deeply rooted in Game Theory Optimal (GTO) principles, though he is specifically praised for his “underrated” live reading ability and stamina. During his 2018 run, he famously focused on “keeping the pot small” pre-flop while leveraging a significant post-flop technical edge to grind down opponents. He is a master of pot control and is known for making very few unforced errors over long sessions. His strategy revolves around a low-variance approach, allowing him to survive deep into tournaments where higher-aggression players often bust out. Whether navigating a WSOP championship or a high-stakes Short Deck tournament, Cynn’s approach centers on technical balance and a relentless focus on making the most profitable decisions for the long term.
