In chess, how many moves are required to achieve a "Scholar's Mate"?

The Scholar's Mate is not the quickest way to achieve a Checkmate - which can theoretically be achieved in 2 moves, the so-called Fool's Mate, but even rank Rookies rarely fall into that trap.

It involves a combination of the Queen and Bishop, and is sometimes referred to as the "Four Move Mate" though it is not the only way to achieve a checkmate in four moves.

Although it is generally only encountered in the lower echelons of the game, in 1999 Woody Harrelson used it as an opening gambit against no less an opponent than Gary Kasparov.

Like many chess terms, it is called by other names in diverse languages, with "Shepherd's Mate" being one of the most popular variants. Rather confusingly, in some languages "Scholar's Mate" is the equivalent of "Fool's Mate", with the "Scholar's Mate" being termed a "Shoemaker's Mate".
