脳内碁盤

This app can do two things:

1. Train the Go game records so that they can be arranged on the board in your head from the first move to the last move.
2. Register and manage Go game records.

The board in your head is called the "brain board" in this app.
Even if you close your eyes, if you can clearly imagine the arrangement of the board and stones, your reading ability will improve and your Go playing ability will improve.
If you can create a "brain board", you will be able to play game records and think about your hands in your head, for example, while walking in the city or taking a bath.
This app is not very useful for people who already have a "brain board" or who do not want to make a "brain board". (It can be used as an application for registering and managing game records.)

In this app, we will memorize the game record and gradually perform training to play it on the "brain board".
The game record is divided into small steps, and "reading with stones", "reading without stones", and "reading in the brain" are performed in that unit.
"Reading with stones" ・ ・ ・ Read while looking at the board on which lines and stones are displayed.
"Stoneless reading" ・ ・ ・ Read while looking at the board where only the lines are displayed.
"Reading in the brain": Close your eyes and read in the brain.
The number of steps to divide starts from one move and increases to 2, 4, 6, 8, 10, 20, 30 ..., up to a maximum of 100 moves.

In the initial state, there are two game records for training on the 9th, 13th, and 19th roadbeds.
These game records are played by a Go AI called "KataGo".

You can also enter the game record by yourself or read the game record file (SGF file) created by other Go apps. You can also output the game record file created by this app for other apps.
