About

Leonard Maue, known online as Grozzorg, is one of the strongest online tournament players in the world and GTO LAB’s primary coach for PKO (progressive knockout) strategy. Known for his technical precision, disciplined study process, and deep understanding of bounty tournament mechanics, Leonard teaches serious online grinders how to extract edge consistently across the toughest fields in modern tournament poker.

Leonard is GTO LAB’s go-to coach for PKO strategy — covering how bounty structures change preflop and postflop ranges, how to counter population over-aggression in PKO spots, and how to leverage your own bounty as a chip lead tool. Beyond PKO, his coaching spans solver methodology, population exploits, and multitabling deep runs across SCOOP, WCOOP, and Triton events. His teaching topics include:

• PKO and bounty tournament strategy — GTO LAB’s primary PKO coach, covering how progressive knockout structures shift ICM calculations, how to counter population over-aggression in bounty spots, how bet sizing from opponents should directly shape your aggression, and how to exploit the unique dynamics bounties create at every stage of a tournament
• Marked hands study workflow — Leonard’s real-world study process: baseline equilibrium first, adjusting to real-game sizings, then node-locking common population mistakes to find practical exploits you can use immediately at the tables
• Population exploits and bad sizings — identifying automatic c-betting leaks in 3-bet pots, attacking condensed checking ranges with small turn stabs and non-linear river bluffs, and exploiting players who under-bluff rivers in multiway and 3-way pots
• Multitabling under pressure — how deep runs across multiple tables create unique ICM-aware decision challenges, and when population reads and timing adjustments matter more than pure solver lines
• ICM prison and final table dynamics — why you must fold premiums like AQs against a massive chip leader, how to adjust inducing ranges to target specific stacks, and the power of the non-all-in isolation play
• BB defense and range construction — check-raise, check-call, and check-fold decisions in 50bb ISO pots, protecting checking ranges with monsters, small blind play under ICM, and the power of the small bet as a counter-intuitive population exploit
• Solver strategy — a 10-part series covering postflop fundamentals, ICM, online and live adjustments, deepstack play, bubble dynamics, and final table strategy from a solver-informed perspective

Leonard’s coaching is built for serious online grinders who want to master PKO strategy, build sharper population reads, and develop the disciplined study habits that drive consistent results across the toughest online tournament fields.
