About

Klemens Roiter is an Austrian tournament professional and GTO LAB coach based in Vienna, widely recognised as one of Europe’s most accomplished high-stakes tournament players. He is best known for winning the 2025 WSOP Monster Stack — a gruelling five-day event — for his first WSOP bracelet and $1,204,457, defeating David Uvaydov heads-up in a tense battle that extended into a fifth day of play.

Roiter is a regular in Triton Super High Roller Series events and has established himself as a formidable competitor across the world’s biggest buy-in fields, combining a technically sound solver-based approach with sharp composure under final table pressure. He plays online under his real name.

At GTO LAB, Klemens’ coaching draws directly from his tournament experience, including a breakdown of the strategic framework behind his WSOP 2025 Monster Stack final table run. His teaching topics include:

• WSOP Monster Stack final table — ICM and FGS breakdown — the macro strategic framework behind his 2025 bracelet win, covering ICM pressure management, Future Game Simulation at critical stack depths, and how to construct a winning approach across a five-day major tournament
• Heads-up warmups for tournament play — how drilling key heads-up spots builds intuition and decision speed for final table play, including specific practice routines to sharpen range construction and timing in the most critical stage of any tournament
• High roller field adjustments — how solver strategy adapts in elite fields where opponents are also close to GTO, and where the real edge comes from precise execution rather than population exploits
• Triton Super High Roller dynamics — postflop and ICM decision-making in the world’s highest buy-in events, where stack-to-blind ratios and payout structures create unique strategic challenges

Klemens’ coaching is built for serious players who want to understand what elite-level tournament execution actually looks like — not just theoretical solutions, but the applied decision-making that wins major events under maximum pressure.
