Impostor chess

Each army has a traitor in it. You can move theirs instead of your own, and they can do the same to you. You can chop a suspect for the price of your move, and lose a good piece if you guessed wrong.

How it plays

1. Your Impostor. One of their knights, bishops or rooks is secretly yours. Move it instead of your own.
2. It betrays. It takes its own side - never their king. No check: take their king to win.
3. The guillotine. Suspect one of yours? Chop it for your move. Wrong, and you lost a good piece.

The details

The masked one

Your Impostor wears a mask only you see. Tap it to move it.

The tell

They never take their own Impostor. A piece of yours they keep leaving alone is a suspect.

Marks

Mark your pieces as trusted or suspect. Only you see your marks.

Two ways

Hidden: it may move for them again and again until you chop it. Reveal on use: its first move unmasks it, and it is yours again after.
