Climbing Silver (棒銀 bōgin, literally "pole-silver") is a shogi strategy.

Climbing Silver involves advancing a silver upward along with an advanced or dropped pawn supported by the rook aiming to break through the opponent's camp on their bishop's side.[1]

Many different Static Rook shogi openings include a Climbing Silver component. For instance, Climbing Silver can played as part of Double Wing Attack, Yagura, or Bishop Exchange openings. (However, there are other variants of these openings that don't include Climbing Silver.) Climbing Silver can also be used against Ranging Rook opponents as well.

The term Diagonal Climbing Silver or Oblique Climbing Silver (斜め棒銀 naname bōgin) refers to a Climbing Silver attack involving the left silver which moves diagonally from its starting position on 7i to attack on the third or second files. This type of Climbing Silver is typical in Static Rook vs Ranging Rook games.

Positioning

In the diagrams to the right, the Black's silver advances to the e file.

Once the silver has reached the e file (S-1e in the adjacent diagram), Black can attempt to attack White's bishop pawn at 2c by advancing their pawn (P-2d). White can capture Black's pawn, but the silver can recapture White's pawn. Because White did not properly defend their bishop's head here, White's camp is somewhat weaker and more susceptible to subsequent attacks from Black.

Similarly, it's also possible to play Climbing Silver when Black has no pawn on the second file. Here the silver can climb to the empty 2e square. And, if there's a pawn in hand, then that pawn can be dropped to 2d.

A subsequent attack by Black, for example, could aim to sacrifice this silver in order to remove White's lance and then drop a Dangling Pawn within White's camp that threatens to promote.

Climbing Silver formations may be used with several different Static Rook openings such as Yagura, Double Wing, and Bishop Exchange.
