Undecided Chess

In Undecided Chess players begin the game with pieces that are "undecided" about which orthodox piece they want to become.

Setup

Rules

All standard Chess rules apply.

Players begin with Undecided Pieces in the place of the usual pieces, except for Pawns and the King, which remain the same.

Undecided Pieces move like Berolina Pawns (one square forward diagonally without capturing or one square forward to capture). However, they do not have a Pawn's initial double move or promotion ability. Undecided Pawns can also move without capturing as any other Piece to become that Piece. Only the usual number of Pieces can be created by each side (two Knights, Bishops and Rooks, and one Queen).

Castling is allowed (unless both Rooks have already been created) and automatically converts the corner Undecided Piece into a Rook.

Note: If an Undecided Piece is captured, it does not have to claim an identity (thereby eliminating a specific Piece to be created).

Note: It is possible to create two same-color-square Bishops.

Notes

Since inventing Undecided Chess, I have become aware of Bario, a more complex chess variant using undefined pieces.
