Quest of the lost systems

Chapter One: Yagura

Section 3: The Morishita System

After the creator, Morishita, lost to the suzume-zashi, the Morishita System was not played anymore when White took G-5b position.

There was one exception, though. It was Habu, who challenged the White suzume-zashi with a new idea. The game was played between Habu(b) and Akira Shima(w) on December 13th, 1994, as Game No.1 in Kisei-sen.

Diagram 15. Up to (w)Bx7e.

Habu's idea was S-9e, but it was not much of an improvement, as the actual proceedings suggested. However, Habu with his gift for victory, came up with a beguiling series of moves after Diagram 15: (b)L*7g(What a move!), (w)B-4b, (b)P*7e(Another stunt!). And yes, Habu won the game. It should be noted, however, even Habu has stopped to induce White to form the suzume-zashi after this. Eventually it was concluded that the above position is not easy for Black to play. Thus, the Morishita System has come to its end, implying that the suzume-zashi will always be a possibility against Yagura.
