"glosik" is an unidentified high stakes PLO player from Ukraine.
"glosik" first appeared on HighstakesDB's radar in May 2011 when he played the $25/$50 PLO cash games on PokerStars and since then he has continued to play the PLO games at both $25/$50 and $50/$100. He exclusively plays PLO online and has not taken a shot at another high stakes game. He was not too active at the high stakes tables until February 2012 when he really started putting in lengthy sessions across numerous tables, and during the three months following that, he won close to $350k.
He is the first notable high stakes pro from Ukraine (not counting Yevgeniy Timoshenko who was born there but brought up in the USA). He plays both short-handed and heads-up, and does not mind playing really deep heads-up against his opponents often sitting with over 500BBs. The account has been registered since at least 2008 so it is not as if he has jumped straight to the high stakes, and people have seen him grind the smaller stakes ($3/$6 - $10/$20 PLO) prior to us tracking him.
