Chess960

Chess960 or Chess960, also called Fischer Random Chess, is a variant of chess in which the initial position is determined by lot. Bobby Fischer, the chess 960 introduced in 1996, with this variant builds on shuffle chess that much longer exists.

There are 960 possible starting positions, hence the name. Because the starting lineup will be determined by lot, the players can not rely on fixed openings . If you do not know what starting position you play, you can not prepare for it and you from the first move at the board think of something. A player can not "lose the hole theory" when played against a human opponent.

*1 Start position  ==[Start  position edit ]  == The initial position of classical chess is one of 960 possibilities. A second arrangement created by swapping king and queen of place. That is substantially different from the rules for castling (see below). In all other cases, the well-known opening theory is no longer applicable.

 * 4.2 players
 * 5 The number 960
 * The placement of the white pieces in the first row is determined by the lot. It will be restricted, there is always a tower left and right tower of the king is (possibly between other pieces). In addition, the stand runners on fields of a different color. Thus, there are 960 different possible starting positions, hence the name.
 * The black pieces are mirrored and in the same order. So, for example against a white horse on a black horse stands f1 f8.
 * The pawns are as usual on the second and the seventh row.
 * The moves of the pieces are unchanged, except for the castling .

Each starting lineup has its peculiarities. In the classical chess in the starting line-up covers all pawns. In Chess960 is not always the case. This weak pawns a major focus in the opening. In the classical chess in the starting line-up covers all documents in the first and eighth row, except for the towers.In Chess960 that can be quite different. ==Castling [  edit ] == In Chess 960 is also a castling defined. Castling is done with the king and one of the two towers, which end up at the usual target field if castling is executed.

The names "long" or "short" castling and castling "on the kingside," or "on the queenside" at Chess960 confusing. We speak rather of castling "in the A-wing" or "on the h-wing."

The following rules apply to the white player:

<p style="margin-top:0.5em;line-height:20.3636360168457px;color:rgb(37,37,37);font-family:sans-serif;font-size:14px;">The conditions for castling resemble the classic chess game:
 * Castling (on the A-wing) with the king and the tower to the left of the king. King and rook to c1 to d1.
 * Short castling (on the H-wing) with the king and the rook to the right of the king stands. King to g1 and rook to f1.

<p style="margin-top:0.5em;line-height:20.3636360168457px;color:rgb(37,37,37);font-family:sans-serif;font-size:14px;">Note that sometimes only the king or only the tower is moved. It is even possible that exchange king and tower place and then castling is already at the first move possible.
 * The king and the respective tower must not be displaced relative to the start position.
 * The king is not in check, and the fields that passes the king (including the target field) must not be attacked.
 * The target field and the fields that are passed by the king and the rook must be empty, apart of course from the king and the respective tower itself.

<p style="margin-top:0.5em;margin-bottom:0.5em;line-height:20.3636360168457px;color:rgb(37,37,37);font-family:sans-serif;font-size:14px;">In the classical chess moving the king two squares means that one is trying to smokers. In Chess 960 sometimes a misunderstanding as the king a single step aside and do the castling is running too slow. In the classic chess is not the case, provided that the king it is moved first. Therefore, it is advisable to announce a castling "I'm going castling now." Another possibility is to take the king from the board, move the tower and set the king on the final spot.

<p style="margin-top:0.5em;margin-bottom:0.5em;line-height:20.3636360168457px;color:rgb(37,37,37);font-family:sans-serif;font-size:14px;">At first glance Chess960 is not substantially different from the initial position only the king and the lady swapped. The agreement, however, ends when we castling as possible move involving it.This move is in both halves of the board (left and right) defined differently. This means that the opening theory there is 960 different positions (not half).

<p style="margin-top:0.5em;margin-bottom:0.5em;line-height:20.3636360168457px;color:rgb(37,37,37);font-family:sans-serif;font-size:14px;">From the moment that the white and the black king can not both smokers, the same theory can be used in two of the 960 by left / right symmetry-related initial settings. The lack of castling as possible move creates a perfect symmetry. A computer chess can take this into account. ==Notation and computer input <span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;font-family:sans-serif;"><span class="mw-editsection-bracket" style="color:rgb(85,85,85);">[  edit <span class="mw-editsection-bracket" style="color:rgb(85,85,85);">] == <p style="margin-top:0.5em;line-height:20.3636360168457px;color:rgb(37,37,37);font-family:sans-serif;font-size:14px;">The format of the castling is as usual: ooo for castling on the a-side and oo to the H-side.

<p style="margin-top:0.5em;margin-bottom:0.5em;line-height:20.3636360168457px;color:rgb(37,37,37);font-family:sans-serif;font-size:14px;">With computer programs imports must often be entered in the form of a regular move, for example KE1-c1, or by clicking with the mouse on e1 and c1. In standard chess, it is then clear to the computer program that there is a castling performed, but not always at Chess960. One solution is to pretend that the tower with the King being beaten. So when the king and rook on g1 and b1 are then gives one Kg1-b1 on. The computer will understand that a castling is designed and plays Kg1-c1 and d1-Rb1. ==The determination start position <span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;font-family:sans-serif;"><span class="mw-editsection-bracket" style="color:rgb(85,85,85);">[  edit <span class="mw-editsection-bracket" style="color:rgb(85,85,85);">] == <p style="margin-top:0.5em;line-height:20.3636360168457px;color:rgb(37,37,37);font-family:sans-serif;font-size:14px;">The starting position can be pre-determined by the tournament officials. Other possibilities are: ===Dice Procedure <span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;"><span class="mw-editsection-bracket" style="color:rgb(85,85,85);">[  edit <span class="mw-editsection-bracket" style="color:rgb(85,85,85);">] === <p style="margin-top:0.5em;line-height:20.3636360168457px;color:rgb(37,37,37);font-family:sans-serif;font-size:14px;">To randomly draw the pieces can be a dice to use. The procedure is as follows:

===<span class="mw-editsection-bracket" style="color:rgb(85,85,85);"><span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;">[The  players <span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;">edit <span class="mw-editsection-bracket" style="color:rgb(85,85,85);">]  === <p style="margin-top:0.5em;line-height:20.3636360168457px;color:rgb(37,37,37);font-family:sans-serif;font-size:14px;">The two players take turns putting a white piece on the board, obviously taking into account that the runners must be on different color and that the king should be between the towers. Then the black pieces and pawns are put on the board and the game can begin. ==<span class="mw-editsection-bracket" style="color:rgb(85,85,85);"><span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;font-family:sans-serif;">[The  number 960 <span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;font-family:sans-serif;">edit <span class="mw-editsection-bracket" style="color:rgb(85,85,85);">]  == <p style="margin-top:0.5em;line-height:20.3636360168457px;color:rgb(37,37,37);font-family:sans-serif;font-size:14px;">The number of 960 can be calculated easily as follows.
 * Throw the dice and move according to the pitch, a runner on 1st, 2nd, 3rd or 4th black field. 5 or 6 is thrown, throw again.
 * Throw the dice and move according to the pitch, a runner on 1st, 2nd, 3rd or 4th white field. 5 or 6 is thrown, throw again. There are now six fields freely.
 * Throw the dice and move according to the pitch, the lady in the designated field. Turn on the count the fields on which a piece is all.
 * Throw the dice and move according to the pitch, a horse in the designated field. Turn on the count the fields on which a piece is all. 6 is thrown, throw again.
 * Throw the dice and move according to the pitch, a horse in the designated field. Turn on the count the fields on which a piece is all. 5 or 6 is thrown, throw again.
 * There are three fields now free. Put the king on the middle field and the towers on the other two.

<p style="margin-top:0.5em;line-height:20.3636360168457px;color:rgb(37,37,37);font-family:sans-serif;font-size:14px;">Multiplying these factors gives 4 × 4 × 6 × 10 × 1 = 960 possibilities to place the pieces in the first row. One is the classic starting position.
 * For one runner are 4 white fields available in the front row, the other runner 4 black fields.
 * Then the lady are 6 spaces available.
 * Then there are five fields available for two horses. That gives (5 × 4) / 2 = 10 possibilities.
 * Thereafter tower king + + tower, placed in that order on the three remaining fields. That can only be one way.
