Daniel Marks

Daniel Marks, better known by his online alias "Markuis," is a professional poker player and instructor who has carved a niche in heads-up no-limit hold'em cash games. He is a featured coach for CardRunners, where he shares his expertise through live-play commentaries and strategy videos.

Marks is a heads-up specialist who frequently plays multiple tables at stakes such as $1/$2 and $100NL. He emphasizes adaptability, particularly against opponents who call three-bets frequently or play loose-aggressively. In one session, he notes that if an opponent "calls reraises very often," his range includes many non-premium hands, so Marks adjusts by three-betting with value hands like king-ten offsuit and queen-ten offsuit. He also discusses meta-game considerations, pot-to-stack ratios, and the importance of building a player profile from early actions.

As a CardRunners instructor, Marks produces training videos that analyze live hands and explain his decision-making process. Topics include playing against habitual three-bettors, adjusting to loose-aggressive players, and managing tricky spots. His videos are designed to help students improve their heads-up and cash game skills.

• In a 2012 session, Marks played four tables of $1/$2 heads-up with a $200 max buy-in, focusing on three-betting adjustments.
• A 2013 session featured him battling his nemesis "Sliikz" across four tables at $100NL on PokerStars, where he discussed meta-game and reads.
• In 2014, he released a video on playing against loose-aggressive opponents heads-up.
• A 2015 video showed him two-tabling $100NL on Full Tilt, building a opponent profile from a single continuation bet with second pair.

While not a tournament grinder, Daniel Marks has made a mark (pun intended) as a respected coach and heads-up cash game specialist. His contributions to poker education, particularly in the nuanced format of heads-up play, have helped many players refine their strategies.
