Double check
Checking the enemy king with two different pieces on the same move is a powerful play! Double check!
The enemy is unable to block or capture both threats at once, so the king must always move to safety.
It is time to test your knowledge and skills! Note, these solutions often require thinking 1, 2, or even 3 moves ahead!
