|One way to classify compositions is to look at the piece count.
This is a kind of 'Economy of Smallness' meaning the less pieces you need to
express an idea, the better your work is.
*If black has only a lone king, the problem is called Rex Solus.
(If white has only a lone king the problem is busted )
*If white has only one piece in addition of the king, we call it Minimal problem.
*If the total number of pieces is four (4), then we have a Miniproblem or Wenigsteiner.
*If the total number of pieces is seven (7) or less, the problem is a Miniatyre.
*Finally if the piececount is 8-12, the problem is known as a Meredith.
(Based on the preference of composer William Meredith 1835-1903 )
What about classifying problems based on different mates?
You would think that a mate is a mate is a mate.
Not so in the world of chessproblems: 'Mates are not created equal.'
* A mate involving all white officers (king excepted) is called an economical mate.
* A mate, where each square around the king is taken only in one way is called a pure mate.
Each such square is either controlled by one of the opponent's men or blocked by an own man.
If a blocking piece is pinned and without pin there is no mate, then the mate is still
considered pure and the pinning piece is involved in such mate.
* A mate that is pure and economical is known as a model mate.
* A model mate involving all men in the board (white and black) is called an ideal mate.
There is a school of thought, called Bohemians, that emphasizes the use of model mates in the compositions.
You could say that they prefer 'the form over content' in a chess problem. These Bohemian type compositions tend to be light (airy) with multiple model mates in variations.
One typical example from a recognized champion of the school is given below.
Miroslav Havel, 1900
Note the different modelmates after black king moves.
There are only three kinds of chessplayers - those who can count and those who cannot....
