user34121: When discussing armageddon chess, I've seen the term "bidding" being used a lot. I understand the following:
"In bidding armageddons, players usually communicate privately how much time they're willing to give up to play with their desired color. The player who gives up the most time wins."
I know the basic rules of armageddon chess, but I don't fully understand the process for bidding. How exactly do players "bid"? And, what is the point of doing it privately? Also, are there cases where bidding is not used?

user18809: The most common way to perform bidding in armageddon rounds is to write your bid down on a piece of paper and give it to the arbiter without showing it to your opponent.
Then the arbiter will reveal both bids. The player willing to play on less time will get the Black pieces and draw odds.
