Book cover of 'Mahjong Combo Theory: Estimating Honchou Rate and Push-Pull Tactics'

❑ Highlights

Combo theory is a theory that breaks down waits into a new unit called 'combos' and compares their danger levels.

In this theory, the opponent's waiting tiles are viewed not as 'suji' (sequences), but as combinations of possible mentsu (melds) and waits (number of combos). This allows for a quantitative explanation of why the danger level differs even for the same 'muesuji' (non-sequential) tile.

By understanding the content of this book, you will be able to do the following: 1 Recognize the difference in danger levels even for the same 'muesuji' tile. 2 Estimate the honchou rate (chance of discarding into an opponent's winning hand) and the opponent's scoring hand, and compare push-pull decisions numerically. 3 Break free from push-pull decisions based on intuition and repeatedly make advantageous choices.

Push-pull decisions can be 'calculated,' not just 'felt.'

This book is explained in full color on all pages, and when you master this content, your skill level will surely advance to the next stage.
