Vertical Cylinder
The verticals "a" and "h" are adjacent: for example, the king , while on the field a5, can go to the fields h4, h5 or h6; rooks in initial positions protect each other. All verticals are equal, the board has no vertical edges.
Some pieces ( queen , rook, bishop ) can single-handedly declare a double check. For example, the bishop or queen on c5 gives a double check to the king on g1 - the “diagonal” c5-d4-e3-f2-g1 and c5-b4-a3-h2-g1 intersect at two points. A rook or a queen, being on the same horizontal with the enemy king, puts him a double check if there are no other figures and pawns on the horizontal.
The initial placement of figures and the rules remain normal. The “round-the-world” moves in which the position on the board does not change (for example, F3-a3) are prohibited (in other variants, including in a chess composition). Sometimes two additional types of castling are allowed: “superlong” (La1 — f1, Kre1 — g1) and “super-superlong” (Lh1 — d1, Kre1 — c1); in other cases castling is generally prohibited. In cylindrical chess, the bishop is close in strength to the rook.
Horizontal Cylinder
Similar to the vertical cylinder, the 1st and 8th horizontal lines are adjacent.
Folding the board in two directions
The left edge of the a1-a8 board is glued to the right h1-h8, and the edge a1-h1 is glued to itself, but rotated 180 degrees. The a8-h8 edge is glued in the same way. [1] The initial placement of figures may remain unchanged.
