Bishop and knight checkmate

In chess, the bishop and knight checkmate is the checkmate of a lone king by an opposing king, bishop, and knight. With the stronger side to move, checkmate can be forced in at most thirty-three moves from almost any starting position.[1][2] Although this is classified as one of the four basic checkmates[3][a], it occurs in practice only approximately once in every 6,000 games.[4]
