Pawn-race misplay
And you — how often have you allowed it?

What is it?
A lost pawn race is miscalculating an endgame where both sides push a passed pawn towards promotion: you promote one square too late, or the enemy queen arrives with a check that changes everything. The margin is often a single tempo.
How it happens
It happens by miscounting the moves to promotion, forgetting that the new enemy queen can give check or capture your pawn, or overlooking that your king sits in the line of fire. One tempo lost, and the race flips.
How to avoid it
Count precisely the moves of each pawn to promotion, and look at what the first queen does: does it check? does it stop the other pawn? Keep your king out of checks and, if needed, gain a tempo by pushing with a threat.
Train this motif
Draw the square of the pawn: one side runs straight from the pawn to its promotion square, the other sides complete it towards the defending king. If the pawn runs alone and that king can step into the square on his move, he catches it. Otherwise, do not chase — push your own pawn.
Two kings facing each other on a file or a rank, a single square between them: the side that does NOT have the move has the opposition, and the other must step aside. With your king in front of your pawn and his still in front of you (not a rook pawn), having it is enough to win. With your king beside your pawn or behind it, it is not always enough.

Frequently asked
- How do I know who wins the race?
- Count the moves to promotion for each; the faster one promotes first. But check whether the first queen can, with a check or capture, stop the enemy pawn — that often overturns the raw count.
- What is the rule of the square?
- A trick to tell, without counting move by move, whether a lone king catches a passed pawn: draw the square whose side is the pawn and its promotion square; if the king can step into it, it stops the pawn.
