Two Pieces in One Chess or TPIO Chess represents a fairy condition in which white and black pieces change their value by unifying two pieces that move to the same square; unification is accomplished by moving the lower value piece, followed by moving the upper value piece.

The composition and decomposition of a TPIO piece is a reversible process. The decomposition of a TPIO piece is made in the opposite direction to its composition. It will be compulsory to follow the thematic square of composition and the place of the original pieces. Any other fields and moves will be considered non-thematic.

Rules to be observed when composing a TPIO Chess:
- the unification of the two pieces will be of the same white or black color, it will be made on the same field and the moves will be consecutive,
- the problem without the condition "TPIO Chess" will have no solution, if it exists then it will be eliminated,
- are allowed: DUPLEX, Zeroposition, neutral pieces, Circe, Madrasi etc.
