Tsukata Special: wondrous new discovery (1)
Tsukata Special deserves to be called revolutionary, in the sense that its
blitz-attack concept made a strong impact not only on the aigakari (double
wing attack) but also on many other strategies. For instance, the furi-bisha
openings which used to be regarded as rather passive strategies are now
recognized as something that can be quite aggressive against slow tactics.
Thus, offense is considered more important in today's game theory. The idea
behind all this may well have been the Tsukata Special.
Diagram 1 shows the very early stage of the game, which gives an impression
that the players are yet to decide their openings. But here already, lurks
a possibility of skirmish.
