I’d say one of the most underrated skills is adaptability.
A lot of players study charts, odds, and ranges (which is crucial), but they struggle when the game shifts outside of what they’re comfortable with. Great players can adjust their strategy based on stack sizes, table dynamics, image, and even how this specific opponent has been playing the last 20 hands.
It’s not just about knowing what the “right” move is in theory — it’s about recognizing when the situation calls for breaking from default strategy. The ability to shift gears, tighten up, open up, exploit a tendency, or suddenly go passive/aggressive is what keeps opponents guessing and prevents you from being predictable.
In my opinion, adaptability is the bridge between technical knowledge and actually winning consistently.
