A tempo is a single move thought of as a unit of time — and “gaining a tempo” means you make a genuinely useful move while simultaneously forcing your opponent to waste one.
Chess is a race to get your pieces out and your plans rolling, so every move counts as time. If you develop a piece and attack something at the same time, your opponent has to stop and deal with the threat — burning a move that doesn’t improve their position — while your move improved yours. You just went one step ahead in the race. The flip side, “losing a tempo,” is when you waste a move: shuffling the same piece twice, or getting a piece kicked around so you have to move it again.
The classic example is above: in the Scandinavian, White develops the knight to c3 with a threat, so Black has to waste time moving the queen yet again. Whole opening reputations hinge on these little time-gains and time-losses — a gambit, for instance, is often a pawn sacrificed to buy several tempi of fast development. Count the tempi and you’ll understand why some openings feel like you’re always a step behind.
