Table tennis game target is wrong · case 05

An 11-9 game is not recognized as finished.

Member previewVariant 5 · 3 implementations · 9 checks per implementation

Case contract

One table tennis game to 11 with a two-point lead; later rallies are ignored. Service changes after every two points; once both players have at least 10 points it changes after every point. Return [a, b, winner, None] when finished, else [a, b, None, next server].

Why this case matters

Match software must show who serves next, especially after 10-10.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
