Perfect Endgame Chess is regular chess except whenever a game reaches an n-piece endgame, the game ends according to its theoretical result. Currently there are tablebases for every position with up to seven pieces, so I suggest Perfect 7-Piece Endgame Chess.
*Inspiration*
Yesterday a series of ultrabullet games were played between top players GM penguingim1 (#2) and IM Satranc_Youtube (then #4) (lichess.org/player/top/200/ultraBullet). penguingim1 complained that he was unable to gain rating points against Satranc_Youtube even though he was achieving superior positions in nearly every game. This is because Satranc_Youtube was extremely fast and able to flag penguingim1 in several losing endgames. I agree with penguingim1 that this current ultrabullet meta is undesireable.
The Perfect Endgame variant would fix the problems with the currently ultrabullet meta. It would improve the incentives to make high quality moves in bullet and blitz time controls as well. In general, there would be fewer tricks and less flagging, yet players would still need to play quickly to win.
