The longest game dispute just got messier. Readers caught an important error in the series examining record-breaking endurance matches: the Arsović-Nikolić game doesn't qualify as a "master game" at all. Arsović started at 2200, which translates to roughly 1400 by modern standards. Nikolić held only a 15-point rating advantage. That's club-level chess, not master-level competition.

This matters because the Guinness record classification matters. If Arsović-Nikolić doesn't count, the Gorkov-Golubenko game becomes the main contender for longest by move count. But the author has dug deeper and found other "competitors" lurking in chess history that also demand examination.

The series reveals how sloppy historical record-keeping can be in chess. A game gets listed as a "master game," readers trust it, databases copy it, and suddenly myth becomes fact. The real longest game by moves remains unsettled. There are other candidates waiting to be properly verified and compared.

What matters now is careful documentation. Ratings must be verified. Definitions must be clear. The chess world has played many marathon games across centuries. Finding the true longest one requires rigor, not assumptions.
