dan-constantin.gurgui(17.08.2018) Interesting fairy condition which was new to me. Welcome to Dan-Constantin Gurgui! Is there a possible improvement of the twin form?
a) 1.Ke4 Be3 2.Bd5 (B+R)e3#
b) 1.Ke5 Sf4 2.Be4 (S+B)f4#
c) 1.Bc6 Bf4+ 2.Kd5 (B+S)f4#
Two Pieces In One Chess or TPIO Chess by Dan-Constantin Gurgui (Romania)
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 value of the six pieces of chess on a scale of 6 to 1 will be the following: Queen 6 points, Rook 5 points, Bishop and Knight 4 points, Pawn 2 points and King one point.
Table of how to form and represent TPIO pieces
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, Zero position, neutral pieces, Circe etc.

Interesting but tough to grasp. I think it will take some more time for me to analyse and understand the strategy of this problem.

The problem does not show the idea of composing and decomposing the TPIO fairy pieces.
The original idea was not accepted for publication.
I'm waiting for it to be accepted.
