Most of your profit comes from their mistakes
At low and mid stakes you don't beat opponents with perfect balance — you beat them by spotting how they play badly and doing the opposite. A calling station that never folds, a nit that folds too much, a maniac that bluffs too often: each leak has a clean, mechanical counter. This trainer names the player type, drops you into a spot, and grades whether you found the exploit. Learn these adjustments and you'll win far more than any chart alone can give you.
