A helpmate is a type of chess problem in which both sides cooperate in order to achieve the goal of checkmating Black. In a helpmate in n moves, Black moves first, then White, each side moving n times, to culminate in White's nth move checkmating Black. (In a helpmate in 2 for example, sometimes abbreviated h#2, the solution consists of a Black move, a White move, a second Black move, then a second White move, giving checkmate.) Although the two sides cooperate, all moves must be legal according to the rules of chess.

A helpmate is a type of chess problem in which both sides cooperate in order to achieve the goal of checkmating Black. In a helpmate in n moves, Black moves first, then White, each side moving n times, to culminate in White's nth move checkmating Black. (In a helpmate in 2 for example, sometimes abbreviated h#2, the solution consists of a Black move, a White move, a second Black move, then a second White move, giving checkmate.) Although the two sides cooperate, all moves must be legal according to the rules of chess.

The example problem illustrated is a helpmate in 8 (or h#8) by Zdravko Maslar, published in Die Schwalbe in 1981. The solution is (''recall that in helpmate solutions, Black's move is given first): 1. Kf3 Kd3 2. Bb3 Kc3 3. Ke4+ Kd2 4. Kd4 Ke2 5. Kc3 Nb4 6. Kb2 Kd2 7. Ka1 Kc1 8. Ba2 Nc2
