Review of the mahjong book on tile efficiency, "Uzaku-style Mahjong Learning" (Uzaku Book) (Author: G. Uzaku)

For a year and a half after my child was born, I took a break from Tenhou (an online mahjong platform) and hardly played mahjong at all.
However, when a new book is published by an author I trust, I can't help but want to read it.
So, this time, we'll be looking at a book written by Mr. Uzaku about tile efficiency."Uzaku-style Mahjong Learning: Tile Efficiency"I will briefly introduce it.

The positioning of this book

This book isReference book on tile efficiencyI think that's how it will be positioned.
For those who learn best by solving many problems and memorizing them through practice, I recommend "301 Essential 'What to Discard' Problems" or "300 Masterpiece 'What to Discard' Problems" over this book.
If you're the type of person who prefers to understand the basics using a reference book before tackling problems, then I recommend reading this book and then moving on to a problem set.

Who would you recommend this to?

I felt this book is recommended for beginners to intermediate players who want to systematically learn about tile efficiency.
If you've never heard of terms like "5-block theory" or "2-head theory," you'll find a lot to gain from this book.
Even advanced players will find this book useful for checking details and reviewing, as it systematically and carefully summarizes tile efficiency.

About the content

The content is divided into the following chapters:
Chapter 1: Blocks
Chapter 2: Head
Chapter 3: Tarts
Chapter 4: Complex system
Chapter 5: How to find and count waiting items
Chapter 6: Techniques
Chapter 7: Efficiency of Singing

For those familiar with reading mahjong strategy books, simply looking at the titles of these chapters will give you a good idea of what they're about.
Each page presents an example problem related to the theme, along with the answer and its explanation.

thoughts

Since I had already read "301 Standard 'What to Discard' Problems" and "300 Masterpiece 'What to Discard' Problems," there weren't many new discoveries for me.
However, since I haven't completely mastered the previous two books, reading this book served as a review and allowed me to solidify the information in my mind from a different perspective.

With so many good books like these coming out, I feel like the level of online mahjong is improving.
Conversely, if you thoroughly read these kinds of books, you'll have more opportunities to gain an advantage over mahjong players who don't.
I've also dropped from 6th dan to 5th dan, so I'm hoping to get back up to 6th dan quickly and challenge for 7th dan.
