Smarter feedback, not just more feedback.
Don't give equal attention to each of your inaccuracies. Study the 20% of positions that will win you 80% of your games.
Most tools like Chess.com's review will point out every inaccuracy from a single game. But without broader context, every mistake gets equal weight — even in positions rare to you, that you'll likely never be in again. Blunder does it differently. By batch analyzing all of your games, it surfaces the mistakes that you repeat. Focus your effort on the positions that you frequent.
