Three Move Quiz Books
The PDF books can be found here.
The basic idea of this quiz game is to guess the best move. The wrinkle is that you pick three moves and rank them. If your top move is the one selected by Fat Fritz, you get 3 points, if its one of your other two moves, you get 1 point. If none of your moves match the recommended one, you get 0 points.
The advantage of this game is that you don't become fixated on one move, but really start considering and evaluating multiple candidate moves.
Here is an example position:
Joseph August Polak v Gerard Oskam, VAS-NRSV, 1940.02.11

If your top move choice matches Fat Fritz's, give yourself 3 points. If one of your other two choices matches, give yourself 1 point. Otherwise no points.

Isn't Leela network X stronger? The truth is there isn't much difference between the playing strength of the best neural networks. What distinguishes them, in my opinion, is how well they deal with certain openings and how useful their advice is for human players. In my experience, the Leela networks have definite weaknesses in certain openings, while Fat Fritz is more well rounded. Ultimately you'll have to decided for yourself if the recommended moves are useful.
