Why one-game review isn't enough
Reviewing a single game is valuable. But the most useful insight—what you consistently get wrong—only emerges over hundreds of games. A single review tells you "you blundered on move 24." Your pattern library tells you "you consistently miss tactical threats when you're in time trouble in endgames."
