You can see the process of acquiring Shogi knowledge from the game records.
Self-play games without noise. Each game uses same weight.

You can see the transition of opening moves.


Self-play games for training.
Self-play games for every 10,000 games added. The top of the page is the latest game. It will be updated every other day.

These are self-play games for training. It often plays blunder for the first 30 moves.
And sometimes it choose a move that is not a best by adding noise on root node.
