A final pot can create the tie
Under WPBSA’s current rulebook, equal scores after the final-black outcome lead to the re-spotted-black procedure when aggregate scores are not relevant. The players draw lots for the next-player choice, and the next player starts in-hand.
A player trails 50–57 and legally pots the final black. Adding seven gives 57–57. The table was cleared, but the numerical result explains why the black returns instead of the frame simply ending with a winner.
The deciding phase is not a new full frame
Retain the tied score rather than resetting the whole match graphic. The re-spotted ball supplies the deciding phase of that frame, not a fresh rack of fifteen reds. The first pot or infringement then decides it under the stated procedure.
The arithmetic is original and deliberately avoids an aggregate-score competition, where the wider calculation can matter. It shows why a dramatic final pot may be celebrated as a route to a decider rather than an immediate frame win. Read the scores before and after the seven-point addition before interpreting the black being replaced.
