Code Geass usually gets its chess wrong, by using the game as a metaphor rather than caring about its strict regulations. The first episode demonstrates this with the line "If a king doesn't lead, how can he expect his subordinates to follow?" Good leadership, indeed, but terrible chess. Usually. But in the game featured in the first episode, the fastest win is in fact with the king, which forces mate in three more moves.
Да ладно? Кто помнит партию?
