Konstantin Abbakumov is a professional poker player and poker analytics specialist with 6 years of experience in No-Limit Hold’em cash games. Over his career, he has gone from independently studying strategy and analyzing hands to working as a technical specialist for poker teams, where he focused on poker software, analytical infrastructure, and supporting professional players.
Konstantin is the author of a series of educational articles about Hand2Note on Hand2Note Guide, where he helps players understand poker statistics, HUDs, popups, hand databases, and the practical use of Hand2Note in their study process. He is also the creator of Exploit HUD, a poker HUD product available in the official HUD Store.
Konstantin’s key specialization is working with ranges, hand databases, and poker statistics. He knows how to turn complex data into clear strategic conclusions: which hands to play from different positions, how to read opponents’ ranges, why some decisions are more profitable than others, and how to gradually improve through regular analysis.
Konstantin has worked with large hand databases, created educational materials and analytical reports for players and coaches, and used modern poker tools including Hand2Note, PioSOLVER, GTO+, HRC, and other solutions for studying strategy and testing gameplay hypotheses.
In his FreeBetRange articles, Konstantin helps players understand preflop strategy, learn how to work with ranges, better understand poker software, and build their own study plan. His goal is to explain complex topics in simple language, so players do not just memorize ready-made charts, but understand the logic behind decisions and can apply their knowledge more confidently at the tables.
