Variations' Maps

The overviews at the beginning of each chapter "Variations of ..." may seem somewhat complicated and getting used to, and probably are. Nevertheless, they might help interested readers to identify areas which they wish to devote themselves intensively. If they have then probably found even new sub-variations or improvements to our sequences, it will be pretty easy to determine if, and to what extent, this results in effects on higher-level parts of the variation tree. And even if whole twigs or branches need to be reassessed. We have done our utmost to ensure that these variation trees maps exactly what is shown at length in other parts of the book. Please excuse, should we have overlooked one detail or another accidentally.

Those readers, who do not want to get any deeper into the problem with own investigations, can therefore safely skip these detailed surveys.

The diagrams within the variations' maps display the position at the beginning of the following part of the variation tree. Unmarked stones are moves of our solution, marked stones moves of an appropriate sub-variation.
(.1) @ 57 +Tries to connect top and bottom
{ = First variation for move Black 1;
starts on page 57; result: White wins }
@ 59 +Captures White's group on the left side
{ = Sub-variation for move Black 5 }
@ 58Secures the connection of his own groups
{ = Move 5 of the main line of the first variation for move 1 }
(.2) @ 60 +Tries to capture White's upper group in the hanezeki
{ = Second variation for move 5 }
@ 39Connects his single stone in the lower right to the bottom group
{ = Move 1 of the main line }
+ 3Description of the move in question ... { = Black wins by three points }
++ (Ko)Description of the move in question ... { = White wins with ease; a Ko is involved }
= The result of the lower level variation that starts with this move is better than that of the higher level one.
= This move leads to a result that is worse than that of a lower level one.
{ These marks are due to a few sub-variations that we were not yet able to adjust in the "right" order, i.e. with the initiator "winning". }
"move order" = Change in the order of moves
