Need help with The Woodpecker Training method For those who don't know, the Woodpecker training method consists of gathering a large number of tactic problems (500-1000) and solve them all, then repeat the exact same problems until I can do all of them in a certain amount of time.

The issue is I'm looking for resources that have the required amount of tactic problems that vary from beginner to advanced in difficulty.

Any such books/databases for chessbase15/resources out there that fit my criteria?
