You can take back as long as a move did not capture, or did not include a pawn move.
Agree to take back.
Other person makes a non capture or non pawn move.
Dummy moves the piece back where it was before the blunder.
You move back where you were last move...
Now you are back to where you were in the game.
This can't be done if there was a capture or pawn move.
