Talk:Terminology

Stuff from the old terminology doc with sed used to update formatting
I've put some of these in (edited), but if you want to add more then here they all are. The formatting should be correct if you past into the source editor.

=== 2DChess === Two dimensional chess, i.e. Traditional Chess === 5DChess === ‘Five’ Dimensional Chess, which is 2d chess with time and multiverse dimensions added. This term is actually a misnomer, as there are technically only 4 usable dimensions. The reason that the game and its implementations are called “5d” chess is because the original implementation is the Steam Game titled “5D Chess With Multiverse Time Travel”. The developer of the steam version named the game after the 3 spatial dimensions that humans perceive, and the two added temporal dimensions. === Action === see ‘Turn’ === Active Board/Timeline === Active timelines are timelines that influence the present. An active board is the playable board on an active timeline. A players nth created timeline is considered active if the opponent has created n-1 timelines. All Active timelines resting on the present must be played on in order to advance the present. A timeline is resting on the present if the playable board on a timeline is aligned with the present. === Advancement === Advancement of a board, moves the playable board on that timeline one sub step and flips the color of the playable board. Advancement also locks in the previous sub step as a history board. Advancement of the present moves the present forward by one sub step. === Black Board === A board that is playable for or to for black. Any black board will have an outline colored black. === Board === a two-dimensional state of a chess board. While 2D chess takes place on one, mutable board, boards in 5D chess are immutable. Boards cannot be changed, instead any move made creates a new board. === Branching Move === A move where a piece moves from a Playable board to a History board, thus creating a new timeline. === Buffer Timeline === A timeline created for the purpose of allowing the next created timeline to be further from the origin timeline -- refine this definition. === Check === If a timeline’s advancement allows the opponent to attack any of the moving player’s kings, that timeline is in check. === Checkmate === If a player is in check and has no legal moves, they are in checkmate. === Diagonal === A diagonal line is a line that moves along multiple axes === Diagonal2 === Diagonal Movement is movement along 2 axes. Currently bishops, queens, and princesses can move along diagonals. === Equivalent actions/turns === Two actions or turns are equivalent if they result in the same position. This is trivially the case when permuting two spatial moves within an action. === History Board === A board where a move has already been played. Some call this a past board, however that can be a misnomer with the existence of a shifting present. === Hardmate === Hardmate is a version of softmate such that there is no possible way to stop all of the checks at a specific time step. In other words the checkmate is “Inevitable”. Situations like this can arise when a single 2d board has 2 or more pieces checking kinds in the past. Since the defending player cannot stop the softmate, he must rewind the present and try to win/draw before the time of the inevitable mate. === Inactive Timeline === A timeline is inactive if it does not affect the advancement of the present. === Jump === A move which transports a piece outside its origin board. === Jumping piece === A piece that can cross the void (ie. the knight) - please refine this definition. === Jumping Move === See ‘Temporal Move’ === Jurassic Rook(Queen/Princess) === The act of Jumping a rook several Steps backwards to create a Timeline that is “Archaic”. (Not sure if that's where the actual meaning came from btw) === Latest Board === See “Playable Board” === Leaping Piece/Leaper === See “Jumping Piece” === Legal Move === A move that does not leave the moving player’s king in check. === Layer === The full space contained within a particular L coordinate. Any layer can only contain at most one timeline, but the layer spans fully across time even though the timeline may not.a particular timeline === Mandatory Move === A move that must be made in order to pass the turn. === Move === A movement of one piece. === Moveset === see ‘Turn’ === Multiverse === A group of timelines. === Orthogonal === Orthogonal movement occurs on only a single axi. Only Queens, Rooks, and Princesses move Orthogonally. === Quadragonal === A diagonal on all 4 axes. Only Queens and Dragons may move along Quadragonals currently. === Rewinding the Present === The act of shifting the present backwards in time. === Optional Move === A move that did not need to be made in order to pass the turn, i.e. moving on a board further in the future than the present, or moving on an inactive board. === Past: The ‘past’ is a somewhat confusing term to use in the game due to the shifting present. For instance, is the past relative to a certain board, or the present? For more specific terminology see === History Board, Playable Board. === Pawn Phasing === The act of pushing a pawn in order to create an opening for a bishop time travel past the pawn. Since pushing the pawn creates a window for the bishop movement to move past the pawn, it appears like the time travel is “Phasing” through a pawn. === Playable Board === A board that a player may make a move on, note this is not the same as an active board/timeline. === Ply === One ply is equal to one action, or how 5d chess defines one turn. Ply is meant to clear up ambiguity on whether a turn is meant to represent one player's action, or both players action. For instance, 1.e4 could be a turn or 1.e4 e5 could also be a turn. A ply simply refers to one player, or the first example given of 1.e4. This term is also used when discussing chess engines. (IE. tree depth is in plie). === Present === Defined as the time of the earliest active board/timeline. === Ranging piece === A piece that can move any number of squares in a given direction === Rider/Riding Piece === See “Ranging Piece” === Royal Piece === A piece that is the objective of play. If the opponent is ever able to capture your royal piece, they win. Currently there are only two royal pieces, the king and royal queen. === Softmate === A version of check where the only legal moves involve rewinding the present. === Solved Variant === A variant is solved if there is a proof that with perfect play by both players, an outcome is forced. === Spatial Dimensions === 2D chess dimensions consisting of a rank(x) and file(y) === Spatial Move === A move where a piece’s origin and destination is on the same board. === StaleMate === When the moving player cannot make a set of legal moves to shift the present. === Stale-Checkmate: A checkmate pattern where the opponent may either capture the attacking piece, or move forward the present but not both. Stale-Checkmate also includes instances where the mated player would be in stalemate except they are also in check. This pattern is displayed in the puzzle === Tricky Checkmates I(Highlight To reveal spoiler) === Step === The base unit of time in 5D chess, representing turns passing within a game of 2D chess. For example T1 is 2 steps away from T3. A step consists of 2 sub-steps which are each boards of different color at the same time. === T === Used in notation for the Time dimension === TT === Short For ‘Time Travel’ === T1F7 Sac === When white travels to f7 with a queen or bishop on the first history board of the original timeline in standard play. The strategy was seen as degenerative to the game due to how strong it was for white. This strategy spawned several variants that attempted to fix the problem. Resources on the sac: https://steamcommunity.com/sharedfiles/filedetails/?id=2218187793 === Temporal Dimensions === Dimensions that exist in time, consisting of Steps(T) and Timelines(L) === Temporal Move === A move where a piece moves from one playable board to another. === TimeCheck === A type of check where a piece attacks a king on a history board. === Timeline === a collection of boards that make a contiguous universe or line of play. The game begins with one or more timelines, and new timelines are created when a jump’s destination is a history board, aka when a branching move is made. === Timeline Advantage === When one player has branched more than another player, the player that has branched fewer times is considered to have timeline advantage. This means that the player with timeline advantage can actively branch and push the present back, and the opponent cannot. Timeline Advantage is one reason why branching without reason is considered to be bad. === Triagonal === a diagonal along 3 axes. Only the queen and Unicorn can currently move along triagonals. === Turn === a set of legal moves that allows the player to press the submit moves button and pass play to the opponent. A turn must change the location of the present, either by advancing the present or by rewinding the present. === Turn2 === A unit of time – see step. === White Board === A board that is playable for or to for white. Any white board will have an outline colored black. === Unplayable Board === See History Board. === X === aka. File or column in 2D chess and on a board in 5D chess. === Y === aka. Rank or row in 2D chess and on a board in 5D chess.
