@es_kan If you choose the knight you...
- Win out the commoner
-Lose to the king
-Lose to the general
If you choose the general you...
-Win out the commoner
-Lose to the king
-Tie with the general
So the rational choice would be not to pick the knight over the general

Probably someone is going to drop something inside the box to make the other think it was the diamond. Wonder what Ayaka took or put on the butler's pocket
