Instead of following Black with for a Guzumi Exchange, White pushes into Black's upper left corner with .

Within the Crosscut-Sequence, the forcing exchange in the left centre / at the bottom has not yet been played (which is a matter of CHITOOM only).

The Jûrokubango has just been started.

After Black's Initial Self-Play Success Ratio (the blue line in the diagram) had fallen into the "yellow" range, it has recently returned to the "green" range around 50%.

28b's surplus of won games in the Jûrokubango (the red dot in the diagram) started at -11, which implies that 28b has not yet understood this variation very well.

We will have to wait and see how things develop !

The comments indicate the number of games in which the respective variation was selected.
E.g. "A=19 // B=264" == Variation "A" was played in 19 games, variation "B" in 264 games.

In the upper right corner, the first exchange of a Q17-reduction of White's territory has already been played.

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) finally stabilised in the "green" range between 45% and 50%.

We are looking at a viable solution here !

Recently, however, Black's Success Ratio has fallen sharply, so we will probably have to wait and see how things develop in the further course of the self-play training.

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.

#272 (the chart has not yet been undated):
BISPSR raised into the "green" range, up to 45% again.
