Can I still adjust this to the list of pieces which we are using here?
Yeah, feel free.

Cxi7. The cannon is tricky in these games.

This is a game between HorusTheThird (white) and evert823 (black). Three new pieces are added:
Witch (W)
The witch is transparent to friendly pieces, and she also makes all adjacent pieces (friend and foe) transparent to friendly pieces (but pieces are not transparent for the witch). The witch
does not capture other pieces, but she can be captured. Although pieces are not transparent to the witch, she is very agile; she combines the movement of queen, knight, and can jump
orthogonally and diagonally two squares. Transparency of a piece means that other pieces can move, attack, and capture right through the piece.
Xiangqi Cannon (C)
The Cannon (from Chinese Chess or Xiangqi) moves like a Rook. But in order to capture it must jump over another piece. If it does not intend to capture then it cannot jump.
(So far this is the general rule as known from Xiangqi. But now that the Cannon appears together with the Witch, one more remark must be made here: In order to capture, the Cannon must jump
over another piece which is non-transparent for that Cannon. Without capturing, the Cannon can of course jump over a transparent piece to an onuccupied square.)
Time Thief (TT)
The Time Thief moves like a Queen, but does not have a normal capture. The Time Thief has a special move that is done in 2 steps.
1. Undo your opponents previous move (restore position to exactly the same as before, which might include putting back a captured piece).
2. Move your time thief (like a queen) and capture the piece that moved on your opponents previous turn.
The Time Thief may not undo a move if the Time Thief was captured or if it is unable to capture the piece that moved after undoing the move.
Note that this means the Time Thief must "see" the piece before it moved.
From this it follows, that a King in reach of a Time Thief would put himself into check by moving away.
Conditional check means the state where a King is attacked by enemy pieces, but after a piece would capture the king a friendly Time Thief could restore his King.
It is allowed to keep the King in conditional check, but only if restoring the king would not result in the king to be in check (the king is allowed to be put into conditional check again
however).
After capture of the King, restoring the king with the Time Thief is obligatory.
Castling:
The rules of castling are similar as in classical chess, however, with the board 10 squares wide, the king travels three squares rather than two. The rook finishes adjacent to the king. All
squares between the king and the involved rook must be unoccupied, with the exception of the witch and pieces made transparent by the witch.
Misc: Pawns play the same as in classical chess. Pawns can promote to queen, rook, bishop, knight in addition to Time Thief, Witch and Cannon. Promotions are unlimited (not restricted to pieces that
have been captured).
Other rules of this game are identical with rules of classical chess.
