Your puzzle sets

One fixed set, solved over and over, until recognition replaces calculation — the Woodpecker Method. The point is your solving time falling on every pass through the same puzzles.

Pick a rating band, or an opening you actually play. A thousand puzzles is the classic set. Two hundred is plenty to start — you'll see the whole set seven times either way.
