Tempo (chess)
In chess, tempo refers to a "turn" or single move. When a player achieves a desired result in one fewer move, one "gains a tempo" and conversely when one takes one more move than necessary one "loses a tempo". Similarly, when one forces one's opponent to make moves not according to the initial plan, one "gains tempo" because the opponent wastes moves. A move that gains a tempo is often called a move "with tempo".
A simple example of losing a tempo may be moving a rook from the h1 square to h5 and from there to h8 in the first diagram; simply moving from h1 to h8 would have achieved the same result with a tempo to spare. Such maneuvers do not always lose a tempo however—the rook on h5 may make some threat which needs to be responded to. In this case, since both players have "lost" a tempo, the net result in terms of time is nil, but the change brought about in the position may favor one player more than the other.

Famous quotes containing the word tempo:
“I have never yet spoken from a public platform about women in industry that someone has not said, But things are far better than they used to be. I confess to impatience with persons who are satisfied with a dangerously slow tempo of progress for half of society in an age which requires a much faster tempo than in the days that used to be. Let us use what might be instead of what has been as our yardstick!”
—Mary Barnett Gilson (1877?)
