Time/Tempo/Tempi in Chess

What is time or tempo in Chess? Well, my description of tempo would include two things: first, the number of moves; second, the effectiveness of the moves. My definition of effectiveness? GTD = Getting Things Done. Achieve (necessary) objectives. I will illustrate with several examples.

"TEMPOACCOUNTANT" was able to draw because he did not waste any time going for the pawn. Compare with "TEMPORUPTCY" below.

TEMPORUPTCY wasted tempo by making an "ineffective" first move. He should go after the pawn starting with the first move.

 Last, (extreme) example:

How would you react if somebody challenged you to a game, and said: "I will take Black, but I will make 8 pawn moves before you make your first move. Most people would not like it, ... because "it is not fair". But people do something like that all the time... when they waste tempo (or tempi, one tempo, two tempi,.. 7 tempi...) It is like giving away your turn to make a move! In the example above, after the 8th move, all the White pieces are on "home-squares". So Black has made 8 pawn moves while White was waiting for his turn!

That's the best way I can explain time/tempo in Chess. (NEXT: "GAINING TEMPO" BY MAKING "FORCING MOVES").
