The solver era (roughly 2015-present) transformed poker by providing precise, mathematically optimal strategies. The game before solvers relied more on feel and experience.

Solvers revolutionized poker by providing mathematically correct strategies. Pre-solver "feel" is now supplemented (or replaced) by data. The best players combine solver knowledge with exploitative adjustments. Adaptation to this era is required to compete at serious levels.
