Keyword "last-from?" compares the position to the starting position of the last move.
Keyword "last-to?" compares the position to the destination of the last move or drop.
There is Chess with turn order in white - black - white.
When using the keyword "last-from?" in the 2nd white turn, it returns the position in the previous black turn.
Is there any good idea if I want to return the position in the previous white turn?
Turn order: Player - Piece) position before move >> position after move
1: White - Pawn) "e2" >> e4
2: Black - Pawn) d7 >> d6
3: White - Bishop) c1 >> f4 (current turn)
Move block in the current turn (3rd turn order; 2nd White turn)
"from" - c1
"to" - f4
"last-from" - d7 << This position can be get by the keyword "last-from?".
"last-to" - d6 << This position can be get by the keyword "last-to?".
I want to get the position "e2" in the move bock of 2nd White turn (current turn).
This "e2" is the starting postion of 1st white turn (previous own turn).
With "last-from?", I can only get the position "d7" of 1st black turn. |

I strongly desire to introduce the keywords "second-last-to?" and "second-last-from?", becuase I want to check if the current position is the position at the previous own turn. |

It's been a while since I've written zrf code, but I wonder if you can create a second "hidden" board using dummy pieces and positions. Whenever white makes a move, maybe you can also place the piece on the dummy board location. There would be some details to work out, but this might be a direction for you to pursue. |

Thank you for your reply.
I succeeded in preserving the "second from last" position as a rank and a file by using two dummy pieces.

I created "Triple Move Shogi" that a player moves three different pieces in own turn.
