Yet, it took Gukesh pure luck to win the final game. So it is Ding’s loss than Gukesh’s win. Who is the weakest, your logic?
Ding won the WCC due to a terrible blunder by Nepomniachi. Good as he was Fischer blundered his bishop like a patzer during his WCC match against Spassky and came back to win the match. Chess games between humans are generally decided by somebody making a mistake. Is that luck?
Of course not. To put himself in a position to benefit from that luck he had to play extremely well for the entire match so that it would be even going into the last game.
