Try (chess)

	Try (chess) Phases of play are parts of a chess problem which happen, as it were, concurrently rather than consecutively. Each problem has at least one phase: the ''post-key play'' or ''actual play''; that is, the play after the key (the first move which leads to the problem's stipulation ("mate in two" or similar) being fulfilled). Other phases, which may or may not be present, are: set play: play which would occur if it were the other side to move first in the diagram position (for instance, in a directmate, where it is usually White to move first, set play consists of lines where Black moves first) try play: play after '' tries''; that is, moves which almost meet the stipulation, but which fail, normally to a single Black defence solutions to twin Twins are two offspring produced by the same pregnancy.MedicineNet > Definition of TwinLast Editorial Review: 19 June 2000 Twins can be either ''monozygotic'' ('identical'), meaning that they develop from one zygote, which splits and forms ...

picture info	Chess Problem A chess problem, also called a chess composition, is a puzzle set by the composer using chess pieces on a chess board, which presents the solver with a particular task. For instance, a position may be given with the instruction that White is to move first, and checkmate Black in two moves against any possible defence. A chess problem fundamentally differs from over-the-board play in that the latter involves a struggle between black and white, whereas the former involves a competition between the composer and the solver. Most positions which occur in a chess problem are 'unrealistic' in the sense that they are very unlikely to occur in over-the-board play. There is a good deal of specialized jargon used in connection with chess problems; see glossary of chess problems for a list. Definition The term "chess problem" is not sharply defined: there is no clear demarcation between chess compositions on the one hand and puzzles or tactical exercises on the other.

	Lacny The theme can be understood by reference to the problem to the right: this is the first problem to demonstrate the idea, by Lacny himself (first prize at the Przepiorka Memorial, 1949); it has been much-reproduced. The set play is: :1...Nh2 2.Qd4# :1...c1=Q 2.Ng2# :1...c3 2.Qe4# The key to the solution is 1.Nd2 (threatening 2.Nf1#), after which the mates are changed thus: :1...Nh2 2.Ng2# :1...c1=Q 2.Qe4# :1...c3 2.Qd4# As well as in set play (as in this example) the theme can be shown in tries, more than one solution or twins. The scheme can be expanded to include more defences; in a fivefold Lacny, for example, the defences a, b, c, d and e are met with the mates A, B, C, D and E respectively in one phase and B, C, D, E and A respectively in another. The cycle can also be extended over three phases to make a ''complete Lacny cycle''; here, the defences a, b and c are answered by the mates A, B and C respectively in one phase; by B, C and A respectively in another; ...
