Shogi glossary
Material advantage
Japanese: 駒得
In shogi, a material advantage (koma-doku) means you have gained more piece value than your opponent through captures. It is the main measure of who is ahead in the opening and middlegame, but in the endgame the speed of your attack matters more.
Having gained more piece value than the opponent.
How material is gained
Material changes hands through forks, skewers, pins, trapped pieces and favorable exchanges. Because a captured piece moves from the opponent's side to yours, winning a silver is a double swing: they have one silver fewer, and you have one more to drop. Small gains add up; an early pawn in hand already gives you tools for tapping and dangling pawn tactics.
When material stops mattering
Shogi endgames are races. If your opponent will mate you in three moves and you need five, extra material does not save you. A brinkmate wins even when you are well behind, and players regularly give up pieces to speed up an attack. Count the race before grabbing anything.
Compared with chess
In chess a material lead usually becomes decisive by trading down into a winning endgame. Shogi has no such simplification, since trades refill both hands. Extra material is converted by attacking the king with it, not by heading for a quiet ending.

FAQ
How big a material lead is winning in shogi?
There is no fixed threshold. A rook's worth of extra material is a large lead in the middlegame, yet the player behind can still win if their attack on the king is faster.
