Dear chess friends,
Recently I wrote a book on Tal's tactics.
You can find an article on the book, with some of the harder puzzles, missed by Tal himself, here: https://www.expert-chess-strategies.com/chess-tactic.html.
Most of the puzzles are easier to solve, though, with all of them being fascinating.
That is an essential Tal quality - to make chess fascinating.
The book is available on Amazon.com: https://www.amazon.com/Tactical-Tal-Part-Lyudmil-Tsvetkov-ebook/dp/B07C16MSBW/ref=tmm_kin_swatch_0?_encoding=UTF8&qid=&sr=
as well as other Amazons, in both paperback and ebook versions.
For people following the story with 'The Secret of Chess', below one more review by IM Gerard Welling: https://www.chess.com/blog/Swordfish55/review-the-secret-of-chess.
I hope very much you find this information useful and not too annoying.
That is the life of chess authors.
Best regards,
Lyudmil
