Today Habu won second game of 57th Osho-sen 4-wins match with Challenger Kubo(8 dan) in 93 moves. Habu was Sente player. The game went to Gokigen Nakabisha Ultra Quick Attack opening. Up to the 24th move, it followed the precedents of Sato vs Watanabe played in the 4th game of 78th Kisei-sen and Itodani vs Toyama played on January 15 2008. However, Habu made a new move of B*9f at the 25th move instead of L*6f. And Kubo did not seem to find a good countermeasure against it in this game.
The diagram below is the resignation one. Gote's King would be mated in the following variations;
K-8c N*7e K-7b S*8c K-8a N*7c(mate, replayable by clicking the arrow in the right direction below the board)
K-8c N*7e K-9b S*8c K-8a N*7c
K-8c N*7e K-7b S*8c K-6b N*7d(mate)
K-9e P-9f(mate)
In any case, Gote would not be able to avoid forced mate from the diagram.
Yesterday On January 18 Habu won 1st game of 57th Osho-sen 4-win match with Challenger Kubo(8 dan) in 96 moves. As a result of Furigoma, Kubo became a Sente player. It's easily predicted that Kubo transferred his Rook to his left side in the opening, but Habu's choice was uncertain since he is an all-round player who can play every opening. He chose ai-Furibisha(both ranging Rooks) in this game.
Kubo's move in question from my point of view is 25th P-4f which was the sealed move of the 1st day. That did not allow him to take Gote's pawn advancement to P-2f at the 26th move since Sente would lose the pawn on 4f by Gote's Rook used in a crossing way. As a result, Gote built an strong attacking base at the head of Sente's King.
The diagram below is the resignation one. Sente's King would not be mated immediately. However, Sente's Gold on 2e would be killed by the edge pawn(You should look at the long diagonal line to 3d of the promoted Bishop on 8i) and then material balance would be damaged too significantly to recover for Sente. I guess that's why Kubo resigned the game at that time.
