How many Queens?

icypenguin72

How many Queens can you get on the board in a regular, legal chess game? All moves must be legal and you can control both sides. See what the max amount you can get is.

No, the max is 18, if both sides promote all of their pawns

Learn to recognize the impossible and you will stop asking questions like this one. It will also raise your IQ by 20 points and give you peace of mind in a world infested by trolls.

No I knew it was impossible, I just wanted to see how he/she would continue.

18 queens total but it would be hard to avoid checkmate if it were a game against another.
