This is a chess variant with a key change: The types of each piece is hidden from ones opponent, who must deduce which piece is which from gameplay.

[edit] Note: Proto-idea

To date all variants and tactics, etc, are based on my imagining of gameplay. Yet to be playtested

[edit] Alternative names

  • Anonymous Chess
  • Undercover Chess
  • "Guess Who" Chess

[edit] Game play

Custom pieces must be used, where each piece has a front and a back. The fronts face the enemy lines, and are undifferentiated. The backs name each piece for the controlling player.

Setup would need to be some random chess, variant so that initial layout does not give it away! (see also 'variants' below)

Check - minimum capabilities required to demonstrate check are required (eg, if the queen has been moving only as a bishop to date, and that same capability is part of the check, then there is no need to reveal full queen movement.

Checkmate - as per check.

Castling across check - as per normal chess, though requires opponent to point this out if it's not otherwise known.

A taken piece loses it's anonymity (logic being that on a battle, you can check the identity of a fallen soldier)

[edit] Pieces

I'd recommend scavenging pawns from other chess sets, and labelling them for player identification. I imagine that obelisks would suit a custom set quite well however - or some kind of "celebrity head" on the pieces. ( https://www.google.com.au/search?q=celebrity+head )

[edit] Expected tactics

I foresee two potential game styles:

early bloodbath
when a strong piece gets out early
early caution
nobody wants to suffer an early bloodbath without it being reciprocated!

...and a tendency to play the castles and queen as if they are pawns.

For my taste, I'd allow opponents to tag pieces (eg with small post it notes?) of the enemy with their observations and suspicions of what each piece is.

[edit] Variants

[edit] Lite

  • Pawns are identified
  • Royalty (King and Queen) are identified
  • Rooks/Knights/Bishops are anonymised

[edit] Standard

Royalty pieces are also anonymised

[edit] Extreme

Pawns are also anonymised, in which case shuffling of pieces can take place over all 16 squares (how this affects the shuffling rules, esp for eg, wrt castling, should be agreed before play).

Also, pieces retain their anonymity even after they are taken.

[edit] Quantum

The idea of "pieces are unknown till discovered" is taken to the next level in the (independently created) QuantumChess
