The Haneziki's Tail has its minimum length of two stones.

Instead of following Black with for an early Guzumi Exchange, White plays the Hane in the lower left corner.

The Jûrokubango has just been started.

Over the course of 28b's self-play training, Black's Initial Self-Play Success Ratio (the blue line in the diagram) stabilised in the "red-yellow" range between 80% and 70%. This means that, according to 28b’s current assessment, Black has a clear and distinct advantage.

It is therefore entirely possible that we are dealing with a false positive here !

28b's surplus of won games in the Jûrokubango (the red dot in the diagram) started at -4, which means that 28b has yet a valid understanding of this starting position.

We will just have to wait and see how things develop as the Jûrokubango progresses !

Here, Black has already completed the sequence for reducing White's upper right corner.

The Haneziki's Tail has reached a length of four stones.

Instead of following Black with for an early Guzumi Exchange, White plays the Hane in the lower left corner.

The Jûrokubango has come to an end.

Over the course of the Jûrokubango (bold section), Black's Initial Self-Play Success Ratio (the blue line in the diagram) stabilised in the range between 65% and 60%.

We are looking at a viable solution here, which is easier to play for Black than for White !

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

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

#280:
BISPSR fluctuates in the "orange" range around 70% now.
