This market refers to the tennis match between Nikolaos Koutroubis and Nicholas Campbell in the M15 Heraklion, originally scheduled for October 5, 2026 at 5:30AM ET. This market will resolve to "Over" if the total number of games completed equals or exceeds 22. Otherwise, it will resolve to "Under." All tiebreaks, including any Champions/Super tiebreak, count as one (1) game. If the match is postponed or suspended, this market will remain open until the match has been completed. A postponement alone will not trigger a 50-50 resolution. If the match is permanently abandoned before completion, or if the match has not been completed by October 19, 2026, 11:59 PM ET, this market will resolve 50-50, unless the outcome has already been unconditionally determined based on completed play. An outcome is considered unconditionally determined if it would have been guaranteed under every possible completion of the match played according to the match format published by the tournament organizer for that round, including whether a final set is played as a full set or as a match tiebreak. For example, for a line of 21.5, if play stops at 6-3, 5-6, completing the match would have required at least 2 additional games, resulting in at least 22 games played, so "Over" would resolve as the winning outcome. … (condensed)
