King v King

The recent game from the Russian Teams Championship between Peter Svidler and Ian Neponiachtchi seems to have set some sort of new record. On move 40 Svidler player Kxf4 leaving only the 2 kings on the board. Technically the game should have stopped on move 39 after Nepo played Kxc7 (there is no mate possible after this), but I suspect Svidlers move came before an arbiter could step in.
The record in question is the shortest game to end this way. Now this game isn't the shortest, but it is one of the shortest. The shortest game to end with KvK was only 17 moves, but this was clearly a collaboration between the two players (  Haimovich and Zifroni). The next shortest game (in my database) is 35 moves, one of 10 that finish before move 40. However the players in these games were either unrated or lower rated, but of course a game is still a game.
Therefore the Svidler Nepo game might not be the shortest KvK game, but it is certainly the shortest GM game to end this way. The nearest rival looks to be a 43 move game, and unless there is some implicit collusion in the future, this may be a record that stands for quite a while.

Pretty sure the Chinese Champ from 2015 had a pre-arranged game that was only kings on move 40, maybe even 35.

Both sides only used about 5-10 minutes in this "game" (Zhao-Wei) IIRC.

Those two have another "famous" game where they played 20-odd moves with no captures before repeating moves.

I'm not sure if that counts as a KvK game, because under the Laws of Chess the game ended before the knight was taken.
