Berserk and Ceres seem playing an eternal match for the third spot in TCEC: https://tcec-chess.com/
Fun to watch, but what is the rule if this trend continues? Would TCEC stop the match upon playing X games, say 100 games, and award the third spot to both engines?

Re: TCEC: Berserk vs Ceres - Eternal Match?
Berserk won. In last game it has 2 pawns less, but fortress. Kibitzer SF saw won in about move 95. https://tcec-chess.com/#game=32&round=bz&season=cup14.
Even SF17 with i5 sees it.
