Biography & Poker Background
Margereson represents the United Kingdom and is based in Chesterfield, England.
He built much of his early reputation online under the screen name "Aggro Santos."
The Hendon Mob records more than $7.8 million in online tournament earnings, alongside his live career total of more than $5.4 million.
Margereson's success online eventually translated into major live results around the world.
His biggest breakthrough came in 2018 when he won the WPT Seminole Hard Rock Poker Showdown Championship for $696,740.
He has since competed extensively across major festivals in Europe and the United States, including the World Series of Poker, WPT and EPT.
The second half of 2025 produced another major run of results. Margereson won the PokerStars Open Main Event at EPT Malta before traveling to Asia, where his APT Championship Taipei Turbo victory delivered his first APT trophy.
Asia has since become another important part of his live schedule.
Margereson's first Asian APT cash came at APT Manila in 2025 before his breakthrough title in Taipei. He returned for APT Jeju in 2026 and recorded five cashes during the festival, highlighted by the High Roller victory and his third APT trophy.
Play Style & Strategy
Margereson's online nickname "Aggro Santos" reflects the aggressive reputation he built during his online career, but there is limited detailed public strategy material covering his complete modern game.
His run to the APT Jeju High Roller title did provide insight into how he approached a major live final table.
Margereson was reduced to only nine big blinds during Day 2 before finding ace-king in a multi-way all-in against pocket tens and pocket queens. He improved to trip kings and suddenly found himself back in contention.
Margereson later explained that the hand, followed by two successful coin flips, allowed him to build enough chips to play far more hands and apply pressure.
He entered the final table as chip leader and eliminated several opponents on his way to heads-up play, including Wouter Beltz.
Margereson began heads-up against Yoshifumi Takahashi with approximately a 5:1 chip advantage.
The match lasted only one hand. Takahashi moved all in with ace-nine suited and Margereson called with king-eight offsuit. A king on the flop gave Margereson the lead, which held through the river to secure the title.
His victory in a Courchevel Hi-Lo event two days later also added another mixed-game result to a career dominated by No-Limit Hold'em.
