Oleg Gaisyuk

Oleg Gaisyuk was born and raised in Zaporozhye, Ukraine. He started playing poker in 2016 after spending five years as a sports bettor, where he often made a living from betting. Despite his analytical mindset, he found poker more challenging than betting and began his poker journey on PokerStars, later moving to PokerMatch under the nickname Ollwagos.

Gaisyuk primarily plays micro-stakes multi-table tournaments and cash games online. In a 2020 blog post, he described himself as a microstakes grinder who has not yet won a major tournament but remains dedicated to continuous improvement. His online alias 'Ollwagos' is active on PokerMatch, and he continues to work on his game, emphasizing the importance of constant learning.

Despite his focus on online play, Gaisyuk has achieved notable results in live WSOP Europe events:

• 2017 WSOP Europe Event #8: €1,111 Little One for One Drop – 5th place for €38,046 (~$44,000)
• 2017 WSOP Europe Event #11: €10,350 No-Limit Hold'em Main Event – 50th place for €18,162 (~$21,000)
• 2017 WSOP Europe Event #5: €550 Colossus – 210th place for €1,625
• 2018 WSOP Circuit King's Casino Ring Event #1: €299 Opening Event – 76th place for €827

As of his last recorded live results, his total live earnings stand at $58,660 from 4 cashes and 1 final table.

Gaisyuk is known for an aggressive yet calculated style, leveraging deep-stack play and adapting to opponents' tendencies. He stresses the importance of bankroll management and mental discipline, having learned from his betting background. In his blog, he admitted that early in his career he thought he knew everything, but realized poker requires constant study and improvement—a lesson he now shares with aspiring players.
