Takodori's Entrance to Shogi World

Result of 5th game of 20th Ryuo-sen

The 5th game of 20th Ryuo-sen seven-wins match between Ryuo Watanabe and Challenger Sato on November 28 & 29. The Sente player of this game is Sato. Sato won it in 177 moves. The score after the game is 3-2 led by Watanabe.

The diagram above is the resignation diagram. Why Watanabe resigned the game at this position is, I guess, he lost his fighting spirit since he could not trap Sente's King and let it go away to his camp safely. As a matter of fact, I cannot see how to approach Gote's King if Gote moved B-5e+ after the resignation diagram. I think Gote should have tried to enter his King to Sente's camp as well.
