Re armageddon, there is sometimes bidding ("how much time they're willing to give up to play with their desired color") instead of pre-determined 5min vs 4min.

What happens if the bid is drawn?

    Why the recent obsession with Armageddon bidding?

    @David because of the Airthings Masters that just happened? especially with Magnus' "soul read" I guess a lot of people suddenly found it more entertaining

  • @David I believe armageddon links to chess960. I plan to make a post soon. In xiangqi, their armageddon was invented by Ronghua Hu, their Bobby Fischer.

Depends on the rules being used. A likely scenario is that an additional tie-break would be used.

For example, in the regulations for the 2016 US Championships:

If both Players bid exactly the same amount of time, the Chief Arbiter will flip a coin to determine who shall choose their color.

  • A more elegant solution (that I have not yet seen used though) would be to simply force one of the players to bid an odd number of seconds and the other an even, preventing a drawn bid in the first place.

    Well, that distinguishes the players a priori, so is less elegant in that way. Commented Apr 8, 2023 at 12:04
  • @ChrisB When you flip it doesn't matter because both players are indifferent. They could even give white to lower rated or 1st in alphabetical order. Right? If they both believe 9:37/15:00 is the optimal amount then the even time player is at a disadvantage. However ... If an armageddon bid is drawn, then is it fair to force a re-bid?

  • A coil flip could be used to decide who bid odd and who even. Commented May 31 at 10:49

Update: In 2023 or 2024 Champions Chess Tour, they re-bid. Not sure this is still fair. If they bid the same, then they can flip a coin because they are indifferent in colour. Now that they are forced to re-bid... Idk.
