2024 AMC 8 Problem 17: Chess Kings
A chess king is said to attack all the squares one step away from it, horizontally, vertically, or diagonally. For instance, a king on the center square of a 3 × 3 grid attacks all 8 other squares. Suppose a white king and a black king are placed on different squares of a 3 × 3 grid so that they do not attack each other (in other words, not right next to each other). In how many ways can this be done?
