This is a game between HolographWars (white) and evert823 (black). Two new pieces are added:
Guard (G)
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.
