[edit] Vulcan Standard Tri-D Chess
[edit] Official Rules (Millennium Rules, True 3-D Movement)
Chess originated on Earth in ancient times. No one is quite sure how old the game really is but most scholars believe that Chess in its traditional 2D form stopped evolving and was standardized by the 15th Century C.E..Shortly after Vulcan made first contact with Earth, the game of Chess became the first major cultural crossover. On a planet with a love for logic and the exercise of problem solving skills, Chess offered the one thing Vulcan was in desperate cultural need for… recreation!
Chess took Vulcan by storm and within a few decades chess became more closely associated with Vulcan than with Earth. (In a similar way spaghetti which originated in China and tomato sauce which originated in North America became most culturally associated with Italy). Vulcans hungered for Chess, but traditional chess was becoming less and less challenging to Vulcan players who found it a bit two-dimensional. Many Vulcans began experimenting with various forms of three-dimensional Chess which had developed on Earth during the 20th and early 21st Centuries. Among 3D versions which became popular on Vulcan were Rauschach (a 5x5x5 version), QuadLevel (a 4x8x4 version), Exchequer (a 4x4x4 version), Millennium (tm) Chess and Tri-Dimensional Chess.
As Vulcans began to make Chess their own game they developed their own version of 3D Chess which they found to be the most challenging yet playable version. The Vulcan variant involved combining two versions of 3D Chess which had originated on Earth in the late 20th and early 21st Centuries.
The first was Tri-Dimensional Chess which had a very challenging playing field utilizing three levels of 4x4 boards which only overlapped by two spaces and 4 mobile attack boards. The playing field had been developed by an earthling named Gene Roddeberry and the Rules had been developed by earthlings Franz Joseph Schnaubelt and Andrew Bartmes in the late 20th Centurty. The Second was Millinnium (tm) Chess which had used an 8x8x3 playing field and had been developed by an Earthling named William D'agostino in the early 21st Century.
Vulcans found that they preferred more challenging movement rules than those of Tri-Dimensional Chess and a more challenging playing field than the 8x8x3 field. In the end they grafted the Millennium movement rules into the Standard Rules for Tridimensional Chess. The result became known as the Vulcan Variant of Tridimensional Chess.
[edit] THE PAWN
In the Vulcan variant the Pawn may move 2D as in traditional chess. In changing levels a pawn may move straight up or down one level, or may slope up or down one level (but only moving ahead toward the opposing rank. In its initial move a given pawn may choose to move forward two spaces, or slope forward two spaces.
A pawn may capture only by making a diagonal capture-move. This works 2D just as in traditional chess. A pawn may also capture by moving one space triagonaly. The Pawns at a1, f1, a8 and f8 may make their first move by moving one or two spaces to the right or left so as to allow them to leave their start positions on the Attack boards.
[edit] THE ROOK
In the Vulcan Variant the Rook may move straight up or down or may slope along the same rank or file.
[edit] THE KNIGHT
In the Vulcan Variant the Knight may change levels by moving one space up and two over, or by moving two spaces up and one space over. Only the knight may move over pieces or through spaces that do not exist.
[edit] THE BISHOP
In the Vulcan Variant the Bishop may move diagonally on the same level or may change levels by moving triagonally.
[edit] THE QUEEN
The Queen may move either as a rook would move or as a bishop would move.
[edit] THE KING
The King may move just as the queen but may only move one space at a time.
[edit] DEFINITIONS:
[edit] SLOPING MOVE:
A sloping move is a diagonal move which changes levels within a single file or rank but which slopes diagonally at the same time.
[edit] TRIAGONAL MOVE:
A triagonal move is a move which changes levels diagonally passing through more than one rank and/or file.
[edit] ATTACK BOARDS:
Unlike Standard Tridimensional chess the three 4x4 boards are seen as representing different spaces/cubes at different levels. However Attack boards are seen as being on the same level as that to which they are attached, thus all attack board rules remain the same as in Standard Tridimensional Chess.
[edit] CASTLING:
Castling rules remain the same as in Standard Tri-D Chess.
