Biography & Poker Background
Originally from Leonberg, Germany (and later residing in London), Marvin Rettenmaier was one of the faces of the “German Invasion” of high-stakes poker. Known for his outgoing personality, guitar playing, and “party” lifestyle, he earned the nickname “Mad Marvin.” He served as a sponsored Team Pro for PartyPoker during the height of his career.
In recent years (2024–2026), Rettenmaier has stepped back from the relentless full-time grind, though he still makes occasional appearances at major festivals like the WSOP in Las Vegas, recording cashes in 2025 events.
Play Style & Strategy
Rettenmaier is recognized for a highly aggressive and fearless approach, particularly when leveraging a big stack during the later stages of a tournament. His strategy involves a sophisticated blend of mathematical precision and sharp exploitative reads, allowing him to apply relentless pressure on opponents.
While many modern players focus strictly on GTO-based lines, Rettenmaier’s game is built on adaptability and “feel.” He is notorious for his willingness to take calculated risks and his ability to navigate the complex psychological dynamics of high-stakes final tables. This fearless nature, combined with his deep technical knowledge of No Limit Hold’em, has kept him at the top of the All Time Money List for over a decade.
