that starts with a composed position—i.e. one that has been made up rather than played in an actual game—where the goal is to find the essentially unique way for one side (usually White) to win or draw, as stipulated, against any moves the other side plays. If the study does not end in the end of the game, then the game's eventual outcome should be obvious, and White can have a selection of various moves. There is no limit to the number of moves which are allowed to achieve the win; this distinguishes studies from the genre of direct mate problems (e.g. "mate in 2"). Such problems also differ qualitatively from the very common genre of tactical puzzles based around the middlegame, often based on an actual game, where a decisive tactic must be found.


Composed studies

Composed studies predate the modern form of chess.

However, these studies often include superfluous pieces, added to make the position look more "game-like", but which take no part in the actual solution (something that is never done in the modern study).

's study is one of the most famous of all time. It is White to play and draw. At first sight, this seems an impossible task: if White tries to chase after Black's pawn he can never catch it (1.Kh7 h4 2.Kh6 h3 etc. is clearly hopeless), while it is clear that Black will simply take White's pawn if he tries to promote it. White can draw, however, by taking advantage of the fact that the king can move towards both pawns at once. The solution is 1. Kg7 h4 (1...Kb6 2. Kf6! h4 3.Ke5! transposes) 2. Kf6! Kb6 (if 2...h3, then 3.Ke6 h2 4.c7 Kb7 5.Kd7 allows white to promote his pawn) 3. Ke5! Now, if 3...Kxc6, then 4.Kf4 stops Black's pawn after all, while if 3...h3 4.Kd6 allows White to promote his pawn. Either way, the result is a draw. (See also .) Not all studies are as simple as the above Réti example. This study (first diagram) is by

(first published in ''Magyar Sakkélet'', 1962). White is to play and draw. The main line of the solution is 1. Ra1 a2 2. Ke6 Ba3 3. Bf4 Bb2 4. Be5 a3 5. Kd5 Bg6 6. Bd4 Bf7+ 7. Ke4 Bc4 8. Rg1, but there are various alternatives for both sides. For example, White could try 1.Bf4 on his first move, with the idea 1...Bxa2 2.Bxd6 and 3.Bxa3 is a draw, but Black can defeat this idea with 1...Bxf4 2.Rxa3 Bc2, which wins. To understand why one move works and another one does not, requires quite advanced chess knowledge. Indeed, it will not be obvious to many players that the position at the end of the given line (second diagram) is a draw at all. One of the most notable studies is Leopold Mitrofanov's 1967 first-prize winner. Unfortunately, Mitrofanov's original study was subsequently found to have a , a miraculous defense that enabled Black either to obtain

studies are not valid in modern chess because of changed rules. However, the moves of the king, rook, and knight are unchanged.
