What is "Losing Game"?

How did you search the web for a chess position?

Thanx🙂

Losing game = captures are mandatory, the King is not royal, and the first side to give away all his pieces wins.

In other words, the composer never intended for checking the King to be a factor. Your stipulation is quite a bit different from the one the composer used.
