Take a quick look at what InCube Chess does and how it works. This section also covers some theoretical aspects of three dimensional chess game. How strategy may change and what this leads to.

InCube Chess allows you to play chess game in real three dimensional space. It follows standard rules for all pieces with the only exception that they are expanded to third dimension. Setting new queen if a pawn reaches opponent's base, castle and other principles not directly related to move rules are completely the same as normal chess game uses. This allows everyone who ever played standard chess game start playing InCube Chess without learning much.

Note
InCube Chess is not usual two dimensional board 8x8 cells with three dimensional pieces on it. It is rather cube with 8x8x8 dimensions.

As you can imagine, adding third coordinate to all moves changed gameplay much. First of all, some pieces became more powerful in compare to normal chess game. Second, entire strategy is changed. For example, in InCube Chess keeping heavy pieces in cube center rather than somewhere close to the edge of cube is even more important than in standrd chess. It is also more difficult to do checkmate because king has more moves to espace. This all makes this game an attractive model to reveal new strategies and tactics and in some sense refreshes interest to chess game.

In order to balance increased space on game field, two more raws of pawn were added. They are located in a way to cover all other pieces, so that, "zero move" position is completely protected, same way as in normal chess game. Opponent's pieces are located on diagonal over the game cube and this makes this diagonal a natural field of tenssion because this is the shortest way to reach the opponent base. Though, this does not stop you from using any other ways of approaching the opponent's base if you like it. It is much more difficult to eveluate all possible combinations of game in InCube Chess. You can create your own tactis and try it on computer opponent.

Eventually, there are some changes in piece values. Watching, how nouse plays and seeing, that, say, it allows loosing one piece and protects another one according with principles that you don't understand, may surprise you unless you look at pieces importantce table.

Note
While pieces importance is changed in compare to standard chess game, relative importance is preserved. In other words, pawn is less important than bishop, knight is less important than rook and so on.
Pawn - least valuable piece, does not move far, strikes in way different from moves direction.
Bishop - values roughly three pawns. Moves over diagonals all over the cube but does not really make real danger to the opponent.
Knight - more valuable than bishop. Even if not moves far it creates a sphere of total destruction and attacks most of pieces in a way different from they can do. This makes it perfect candidate for attacking heavy pieces using so called "fork" principle, which is even more dangerous in three dimensional space.
Rook - more valuable than knight. This mostly comes from normal chess tradition and some unique abilities of rook. It can protect perimeter and also can participate castle with king, allowing to make checkmate a bit more difficult.
Queen - naturally most valueable heavy piece. Loosing it means that game is lost with high probability.
King - naturally has the same value with queen, even if not useful enoguh piece.
