Ok, but if white didn't move it's king e5-e6, black would have captured it next move. Then, when black captured the last white piece except the king, white had no legal moves. The rules do not mention stalemate (which this seems to be, as mentioned before), and i have not really played enough of this to know what should happen in this situation.
(hide) If you want to play a game with an opponent of a similar level, you can define a required BKR range for a new game invitation. Then nobody with a BKR outside this range will be able to see/accept it. (Katechka) (show all tips)
