Many basic tactics (手筋 tesuji, also translated as 'clever move') of shogi are similar to those of chess tactics, involving forks, pins, removing the defender and other techniques, all of which are considered very strong when used effectively.
However, other tactics, particularly ones involving dropped pieces, have no parallel in western chess.
Then, Habu executed a bishop trade in which Kimura recaptured with his left knight (22.
In shogi, only lances, rooks (or dragons), and bishops (or horses) can pin an opponent's piece.
Piece sacrifices can be very useful in checkmating situations in order to force the king of one's opponent into mateable position.
The desired effect of this tactic is usually to force the opponent to move their pieces in a certain way in reaction to the threat of the striking pawn.
For example, in the diagrams below, Black is attempting to break through White's camp along the second file at 23 with a dropped pawn supported by a rook on 28.
In subsequent moves, Black cannot win the piece exchanges by promoting the pawn on rank 2 (P-22+) because White can start the attack and there are an equal number of pieces (gold and bishop vs pawn and rook).
When two pieces (usually identical) are captured by each side at the same coordinates, it is referred to as a trade or exchange.
In comparing the start and end board positions of this bishop exchange, one can see that this is as if Black and White both removed each of their bishops from the board and put them each in hand and then Black skipped their turn allowing White to advance their silver to 22.
(Of course, there is a strategical tradeoff in this move which allows White to position their pieces in a way that isn't otherwise possible.)
This is a common tactic since there is a limit on the number of pieces that can protect the edge files.
