Biography

Mateusz Szczecinski is a Polish Brazilian jiu-jitsu black belt and submission grappler known for his intricate guard and devastating lower-body submission game. One of Europe’s top modern no-gi competitors, Szczecinski built his reputation through aggressive attacking sequences and rapid finishes, particularly with his powerful straight ankle lock. He is credited with popularizing the “shotgun grip” when applying the straight ankle lock, a configuration he used to end many matches quickly on the international circuit.

Szczecinski rose to prominence through his strong performances at the European ADCC Trials and later competed at the ADCC World Championships, establishing himself as one of the most dangerous leg-lock specialists in his division. He has also been a frequent competitor on Polaris and other major professional grappling platforms, where his aggressive style and ability to force early submissions made him a standout.

Known for his intricate entanglement sequences, sharp leg-lock transitions, berimbolo entries, and ability to generate immediate breaking pressure, Szczecinski has become one of Europe’s most respected and feared submission grapplers. His finishing-oriented approach, signature straight-ankle lock variations, and fast armbars have made him a consistent threat in every match he enters.
