The pieces · 駒の価値

What each piece is worth.

Shogi has no fixed price list, but every engine keeps one, and ours is below. Two things in it surprise people coming from chess: a captured piece is worth MORE than the same piece on the board, and almost everything promotes into the same thing.

Centipawns, the unit engines count in: a pawn on the board is 100. These are the app's own numbers, read from its evaluation at build time, so this page cannot drift from the bot you play against.

A piece in hand beats a piece on the board

Every row above is worth more in hand than in play, and that is not a rounding artefact. A rook on the board can only act from where it stands and has to travel to matter; a rook in hand can appear on any of the empty squares, this move, wherever it hurts most. Our evaluation prices that at 15% more for a rook and 15% more for a pawn.

The practical consequence runs through the whole game. An even trade is never quite even, because the side who captures last holds the piece. And a player with three pieces in hand and a worse position is often the one to be afraid of, because their attack arrives all at once and yours has to walk.

Everything becomes a gold

A pawn, a lance, a knight and a silver all promote into a piece that moves exactly like a gold, and our table prices all four of them at 600 — the same as a gold itself. That single rule does most of the work in shogi's endgame:

The two big pieces

The rook and bishop are the only pieces that keep their own identity when they promote, adding a king's step to the range they already had. A dragon (龍) is worth 1300 and a horse (馬) 1150 in our table, and both are worth roughly two golds. This is why a bishop exchange in the opening is a real decision rather than a formality, and why so many openings are named after where the rook went.

Note the gap between a rook (1100) and a gold (600): a rook is worth a little under two golds. In chess a rook is worth about two minor pieces; in shogi the ratio is similar, but the minor pieces get their value back by promoting, which the rook cannot do as dramatically.

How to use the numbers

Not by counting them. Engines add them up every move; people use them to answer one question at a time:

And one thing the table cannot price: the king has no value because losing it ends the game. Every number above is worth nothing in a position where you are mated first, which is why our engine's weakest levels are tuned to never give away material for free rather than to count it well.

Where these numbers come from

They are hand-tuned starting values, refined by playing the engine against itself. They are close to, but not identical with, the amateur tables you will see in Japanese books, which usually run pawn 1, lance 4, knight 4, silver 6, gold 7, bishop 9, rook 11 or similar. Any table is a summary of a real position, and a lance in front of a rook is worth more than a lance on the far side of the board no matter what the table says.
