Paperback is out + #100DaysofChess

Just a short newsletter! I just launched the paperback version of 100 Headachingly Hard Mate in two puzzles. Link in the tweet below.

After all this editing and publishing I will get back to chess training with longer time controls. So for the next 100 days I will tweet about my daily training under the hashtag #100DaysofChess.

Best,
Martin
