Chang Hwan Lee

Jack Lee, also publicly identified as Chang Hwan Lee, is a South Korean poker player best known for appearing in high-stakes live cash games, including Hustler Casino Live. His background is primarily in cash games, though he has also competed in major live tournaments.

Away from the table, Lee has described himself as a businessman running four companies across Japan, Hong Kong, and San Francisco. Poker appears to be a serious pursuit rather than his only profession, and he has said that his business schedule limits the amount of time he can dedicate to formal study.

Lee has spoken about using long flights as poker-study sessions, working with tools such as GTO Wizard and reviewing livestream footage to improve his decision-making. He has also said he watches recordings of his own play before deciding what areas of his game need the most work.

His path into poker began as a way to meet people and build professional connections. Over time, he became more serious about the game, evolving from a primarily cash-game player into someone who also enjoys the pressure and strategic dynamics of tournament poker.
