Error in the direct‑encounter tiebreaking system

In Swiss tournaments, when two players are tied on points and have faced each other, the player who lost the game among the tied players takes first place, not the one who won.

Hello, is this the tournament you are looking at? https://my.chesspairings.org/torneo.php?id=2549&tab=classifica

Hello! Thank you @jav for reporting the issue.

You were right: it was a bug in the calculation of the tiebreak by head‑to‑head. In the tournament you mentioned (Comunal Ajedrez sub-18), Alarcon had beaten Salgado in the last round and should have been placed first in case of a points tie, but the system ordered them the other way around.

We have already corrected the logic and the standings now display correctly:

  1. 1st Alarcon, Angel — 4.0 pts
  2. 2nd Salgado, Martin — 4.0 pts

The fix is applied automatically to all Swiss tournaments, so any other affected tournament will be corrected when the standings are reloaded.

Thanks again for helping us detect the problem.
