Fedor Holtz's Poker Strategy: Classifying Opponents for Maximum Gain
Poker player Fedor Holtz has developed a unique system for classifying opponents, which he uses to adapt his strategy and maximize his gains. He categorizes opponents into six main groups, each with its own characteristics and exploitable tendencies.
Nits: The Tight Players
The first category Holtz identifies is the 'nits', who are extremely tight players. They open, defend, and 3-bet narrowly, are passive on the postflop, and usually invest money only with strong hands. Holtz advises playing many small pots against them and folding disciplinarily when they show activity.
Calling Stations: The Passive Investors
The second category are 'calling stations' or 'telephones', who invest too many chips with weak hands. They like to see flops, play postflop, and pay on the river. Against them, Holtz recommends value betting thinly and 3-betting with a wider range.
Solid Regulars: The Correct but Predictable
The third category are 'solid regulars' or 'krepshiki', who play correctly but lack creativity. They make few mistakes and have a good understanding of the game. Holtz suggests exploiting their intuitive hands and predictable lines.
Loose-Aggressive: The Creative Fighters
The fourth category are 'loose-aggressive' players, who fight for every pot. They open wider, 3-bet wider, and are more active in small pots. Holtz advises constant concentration and adapting to their creative plays.

Argus RivenI've spent years at the tables — cash and tournaments — and just as long shaping poker copy behind the scenes: room reviews, bonus fine print, tournament notes. At PokerInsider I write the way I wish more sites would: clear structure, honest trade-offs, no hype. Whether you're new or already grinding, I care about what the offer actually costs you — rake, variance, and the fine print — and I treat responsible play as part of the job, not a footnote.
