How to Break a Castle
Writer: Takashi Araki, a former member of Shorei-kai, who has a third dank rank.
1. Bou Gin Is All Around
There are several attacking forms in Shogi. The most simple and destructive one is “Bou Gin (Climbing Silver)”. When you learn about Bou Gin, you also learn how to link Hi (Rook) and Gin (Silver), how to add pieces, how to remove your opponent’s Kin (Gold) from his/her castle, which are the basics of attacking. It’s one of most important tactics.
Bou Gin is one of attacking strategy in Ibisha, in which your Gin (Silver) advances along your Hi’s (Rook’s) file to break your opponent front. It can be applied in Furibisha, though. When your Hi (Rook) has moved to the 5th file, Nakabisha, the Gin (Silver) moves along the 5the file, and when it has moved to the 4th file, then the Gin (Silver) moves along the 4th file. With all most all strategies, you can use Bou Gin, which is an all-around tactic.
2. . Focus on One Thing at a Time
Bou Gin is really versatile and aggressive attacking method but it also has a weak point. You can’t attack over a wide range with it.
Using Bou Gin, Gin (Silver) literally advances along a straight file line and its attacking range will be narrowed. For example, Kaku (Bishop) can move widely and attack over wide range but it’s not for Bou Gin.
When you apply an attacking form of Bou Gin, you need to focus on one thing at a time. To concentrate your forces on Bou Gin and not to distribute them, it is very important.
3. The Way to Use Fu (Pawn) is Very Important
Now, think from your opponent’s point of view. If your opponent enters your camp using Bou Gin which is a concentrated attack, you may not defence against it. In the first place, you need to think the way to block Gin (Silver) from advancing.
For attacking side, how to proceed Gin (Silver) to an enemy’s camp is important.
When you are attacking and your opponent’s defense is not strong enough, you can proceed Gin (Silver) without difficulties. What if the defense is strong enough to block the route for your Gin (Silver)?
What helps in the case is how to use Fu (Pawn), which is termed Fu no Tesuji in Japanese. It’s not too much to say that the key point to use Bou Gin is the way to use Fu (Pawn).
The powerful techniques tu use Fu (Pawn) are, Awase no Fu (opposing Fu (Pawn)), Tsukisute no Fu (push sacrifice Fu (Pawn)), and Tsugi Fu (joining Fu (Pawn)). They are explained more in our textbook, “Shogi Lesson Book for Beginners Vol. 4”. Please take a look!
