Alisson Miguel Piekazewicz

Alisson Miguel Piekazewicz is a Brazilian professional poker player from Curitiba who has risen to prominence through a combination of online mastery and live high-roller success. He is ranked among Brazil's top players, with live tournament earnings exceeding $4.87 million and additional online cashes of over $3.6 million under the alias "heyalisson." In 2026, he continues to be a regular in elite fields, earning six-figure scores in the Triton Series and EPT.

Piekazewicz began his poker journey in the hyper-competitive Brazilian online scene, quickly becoming a legendary figure on PokerStars. Playing as "heyalisson," he won a Stadium Series title and a World Championship of Online Poker (WCOOP) event, amassing over $3.6 million in online cashes. His technical skills and high-volume grinding laid the foundation for his later live success.

Piekazewicz made a seamless transition to live events, holding his own against world-class opponents such as Alex Foxen and Bryn Kenney. He first gained significant attention in 2024 at the WSOP, where he entered Day 2 of Event #68: $2,500 No-Limit Hold'em with the second-largest chip stack, finishing well despite not reaching the final table. His live breakthrough came in 2025 with multiple deep runs in high-stakes tournaments.

One of Piekazewicz's most memorable moments came during Day 1A of the $8,000 Triton ONE Main Event in Jeju, South Korea, when he made an epic hero call against high-stakes pro Alex Foxen. Piekazewicz opened to 6,000 in the hijack with pocket fours, and Foxen three-bet to 18,000 on the button. Piekazewicz called, then check-raised from 14,000 to 34,000 on a flop of 5♥3♠9♣, leading Foxen to three-bet to 61,000. The bold play demonstrated his fearlessness and ability to pressure even the toughest opponents. He went on to cash in the event, finishing between 11th and 13th place among a field of 447 entrants that included Steve O'Dwyer, Stephen Chidwick, Jesse Lonis, and Stephen Song.

Piekazewicz is known for a highly analytical, solver-backed approach, with a strong foundation in GTO theory. His online background gives him exceptional range precision and post-flop creativity, allowing him to exploit even the world's most aggressive opponents. He emphasizes mental preparation and deep study, often noting that real learning happens outside the books. His ability to adapt from multi-table online settings to live high-pressure championship structures is a key edge.

Recognized as a de facto Brazilian ambassador in the Triton Series and PokerGO Tour, Piekazewicz has become a figure of inspiration for aspiring players in his home country. He frequently participates in elite study groups and podcasts like GTO Lab, sharing high-level insights. Despite his success, he maintains a relatively low profile, focusing on continuous improvement rather than media attention.

As of May 2026, Piekazewicz's live earnings have surpassed $4.87 million, with his latest cash being $159,000 on May 21, 2026. He continues to be a regular in high-roller events worldwide, consistently adding to his record of 111 live cashes. With a blend of online discipline and live adaptability, he remains one of Brazil's most formidable poker talents.
