Enochian Chess

The Pawn in Enochian Chess is simpler than its standard chess counterpart, but has unique promotion mechanics.

Movement

Each pawn moves one square forward in its army's direction:

Pawns move forward (blue circles) and capture diagonally (red circles). Direction depends on army.

ArmyDirectionPromotion Zone
BlueNorth (toward rank 8)Rank 8
RedWest (toward file a)File a
BlackSouth (toward rank 1)Rank 1
YellowEast (toward file h)File h
No Double-Step or En Passant
Pawns move one square only. There is no initial two-square advance and no en passant capture.

Captures

Pawns capture one square diagonally forward (in the direction they move), just like standard chess.

Promotion

When a pawn reaches its promotion zone (see table above), it promotes. But promotion works differently:

Patron Piece

Each pawn is assigned a patron piece type at the start of the game (e.g., "pawn of the queen" or "pawn of the bishop"). Upon promotion, it becomes that piece type.

Privileged Pawn

If an army is reduced to a minimal force:

  • King + Queen + Pawn
  • King + Bishop + Pawn
  • King + Pawn only

...the pawn becomes privileged. A privileged pawn may promote to any major piece type.

The Demotion Twist
If you use a privileged pawn to promote to a piece type already on the board, the existing piece is demoted back into a pawn of that type.

This creates fascinating endgame decisions: do you create a second queen at the cost of demoting your current one?
