The Jûrokubango has come to an end.

Over a long period of 28b's self-play training, Black's Initial Self-Play Success Ratio (the blue line in the diagram) stabilised around 60%.

The Jûrokubango (bold section) resulted in an increment of 5%.

We are looking at a viable solution here !

28b's surplus of won games in the Jûrokubango (the red line in the diagram) has reached the range of 0 to -5 (showing an upward trend).

28b has therefore mastered this variation just as well as 40b.
