| the pawns |
| A pawn can move to any space that both (1) it's vertexually connected to (i.e., a space that touches one of the vertices that the space that the pawn's on touches) and (2) either (a) it's adjacent to or (b) is adjacent to a space that it's adjacent to. There are nine spaces that a pawn can move to from a corner space or from an edge space or from an inner space. |
| As in chess, if a pawn reaches the other end of the playing field, it is queened; i.e., it is turned into any piece of the player's choice other than the king. That will almost always be a queen, and as in chess, on rare occasions it might make sense to queen the pawn into a knight. The other end of the playing field comprises any of the nine spaces on that player's antipode triant. |

| the rooks |
| A rook can move on a path that comprises a latitude around one of six pairs of global poles: each of these 12 poles is a 5-cornered vertex where five triants join together. And each of the six pairs of poles is composed of the 5-cornered vertices that are antipodes of one another. |
| The actual equator around one of these pairs of poles is the path of spaces comprising successive passages through the middle rows of 10 triants where the 10 triants divide the spheroid into two quarterspheroids of 5 triants each. Each quarterspheroid has at its center the 5-cornered vertex where these five triants join together. |
| These paths of spaces that are actually themselves the six equators are the rook's equatorial latitudes. The paths of spaces on either side of the six equatorial latitudes are the rook's penequatorial latitudes. |
| The six equatorial latitudes can also be thought of as the rook's "3,3 x 5" latitudes, since the path that circles the spheroid comprises five successive passages through a triant middle row at one angle and then another middle row at the opposite angle. So the rook's equatorial latitude includes 30 spaces and is on 10 triants: 10 triant middle rows. |
| The 12 penequatorial latitudes can also be thought of as the rook's "5,1 x 5" latitudes, since the path that circles the spheroid comprises five successive passages through a triant edge row at one angle and then a triant corner. So the rook's penequatorial latitude includes 30 spaces and is on 10 triants: five triant edge rows and five triant corners. |
| Three of the 18 rook's latitudes pass through each of the 180 spaces. Which of the two types of rook's latitudes that a rook can move on depend on whether it's moving from an edge space or from an inner space or from a corner space. |
| from an edge space |
A rook can move from an edge space on one of two rook's equatorial latitudes
( or  ) or on one rook's
penequatorial latitude
( ) that pass through the space.
|
| from an inner space |
A rook can move from an inner space on one rook's equatorial latitude
() or on one of two rook's penequatorial latitudes
( or  ) that pass
through the space.
|
| from a corner space |
|
A rook can move from a corner space on one of three rook's penequatorial latitudes
( or or
 ) that pass through the space.

| Thanks to all the participants in the many focus groups for all of your time, effort, and input that have led to the improved (and simplified) moves for the knights, the bishops, and the queen. Look here for descriptions of those improved moves soon. |

| the king |
| A king can move to any space that it's vertexually connected to (i.e., a space that touches one of the vertices that the space that the king's on touches); this includes any space either that (1) it's adjacent to or (2) is adjacent to a space that it's adjacent to or (3) is adjacent to two spaces that are adjacent to spaces that it's adjacent to. There are 11 spaces that a king can move to from a corner space, and there are 12 spaces that a king can move to from an edge space or from an inner space. |
