Fool's mate was named and described in The Royal Game of Chess-Play, a 1656 text by Francis Beale that adapted the work of the early chess writer Gioachino Greco. [2]Prior to the mid-19th century, there was not a prevailing convention as to whether White or Black moved first; according to Beale, the matter was to be decided in some prior contest or decision of the players' choice.

The ladder mate, [17] [18] also known as a lawnmower mate, is by far one of the most common checkmate patterns. In this mate, two major pieces (which can be two queens, two rooks or one rook and one queen) work together to push the enemy king to one side of the board.
The problem is a mate in two (White must move first and checkmate Black in two moves against any defense). The key is 1.Qb1, which threatens 2.Qb7#. Black has three ways to defend against this. One is to play 1...c3, giving his king a new flight square at c4, but this unguards d3, allowing White to mate with 2.Qd3#.
In chess, an ideal mate is a checkmate position that is a special form of model mate.While in a model mate, each piece on the mating player's side (possibly excluding the king and pawns depending on context) participates in the mate, an ideal mate involves all the pieces of the mated player's as well, typically by blocking the mated king's field of movement so that it cannot escape.
The fewest moves required to deliver checkmate in chess is two, in what is known as the fool's mate (1.g4 e5 2.f3?? Qh4# and variants thereof). This happens in amateur play.
In chess, scholar's mate is the checkmate achieved by the following moves, or similar: . 1. e4 e5 2. Qh5 Nc6 3. Bc4 Nf6?? 4. Qxf7 #. The same mating pattern may be reached by various move orders.
Figure 3, before White's second move, is defined as "mate in one ply." Figure 2, after White's first move, is "mate in two ply," regardless of how Black plays. Finally, the initial position in Figure 1 is "mate in three ply" (i.e., two moves) because it leads directly to Figure 2, which is already defined as "mate in two ply."
Helpmate in 2: a) Black moves first and White checkmates, b) White moves first and Black checkmates A further variation is the duplex , another way of getting two problems for the price of one. The first problem is a normal helpmate; the second starts from the same position but has White moving first and helping Black to checkmate him.
