Insurrection is a Chess variant where individual pieces can move up in rank and governments are toppled.

Setup

Insurrection is set up exactly like a regular game of Chess, shown below:

setup

Because of succession you might wish to have addional sets of pieces on hand.

Piece movement

All of the pieces in Insurrection move in the same way that they move in Chess.

Pawn promotion

Pawn promotion occurs just as in Chess, however a pawn can also promote to a King. The implications of this change will become apparent later.

Piece capture

Capturing in Insurrection occurs exactly as in Chess, but the real fun begins once captures occur.

Succession and decline via capture

In Insurrection, any time that a piece captures another piece the capturing piece immediately becomes the same rank as the captured piece. For example, observe the following scenario:

to-capture

If the white pawn on d5 captures the knight on c6 then it will succeed to knighthood (i.e. it becomes a knight itself):

knight-capture

The new knight would put immediate pressure on the black queen. Black might likewise capture the new knight:

knight-capture2

This time the black pawn succeeded to knighthood. However, white might decide to capture the new black knight resulting in the white bishop declining into knighthood. Of course, the queen is once again in danger, but the remaining moves are left as an exercise to the reader.

Piece ranks

The rank of a piece is proportional to its value, therefore the follows piece rankings, from lowest to highest, are observed in Insurrection:

  1. Pawn
  2. Knight
  3. Bishop
  4. Rook
  5. Queen
  6. King

A capture that causes a piece's rank to increase is a succession while one that causes its rank to decrease is a decline. All of the pieces can succeed or decline throughout the course of a game, even the king. Indeed, while the king starts the game as the piece for which a checkmate is aimed, checkmate in Insurrection is really aimed at any or all of the ranks currently in power. The act of forcing one rank into power over another is called a coup.

Coups

Insurrection starts with a monarchy in place. That is, to win the game, a player must checkmate the other player's king -- just like in Chess. However, should a monarchy in power take another piece then a coup will occur in the other player's ranks. A coup describes a change in the government on the board to that representative of the captured (i.e. martyred) piece's rank.

When a coup occurs then any of the remaining pieces of that rank can be checkmated in order to win. The old king becomes a regular piece and can be captured normally.

The only time that a coup does not occur is when a piece in power takes the final piece of a given rank.

Checkmating the government in power

Observe:

to-coup

In the diagram above, should the black king take the attacking pawn then the following board will result:

coup

Unfortunately for white, the coup leads to a catastrophe as the pawn on a2 is placed into check. When a coup leads to a check then the player in danger has one attempt to get out of it. If they are unable to remove the check then they lose. In the case above white has no move that can release the check on the a2 pawn and is therefore checkmated.

Types of coups

The type of coup that occurs depends on the piece captured by an opponent government in power. The names of the types of coups are listed below:

  • King taken: Monarchy (also the starting government)
  • Queen taken: Matriarchy
  • Rook taken: Comité de salut public
  • Bishop taken: Theocracy
  • Knight taken: A junta
  • Pawn taken: Anarcho-syndicalist

It's fun to yell these names out when a coup occurs.

Assassination

If there is more than one piece active for the government in power then all but the last one can be captured, or assasinated. However, the final piece of a government in power must be checkmated.

Acknowledgments

The idea for coups came from a comment that my son said during one of our games about how I might have won if my king was just a regular piece. The basic idea for succession and decline came from a Twitter comment by Daniel Solis.
