Chess in a Toroidal Board

This variant begins with the Cylindrical 8 x 14 Variant . Then, the a and h columns are glued together.

	     White

All other rules (castling, en-passant, promotion, etc) apply - but notice that the board has no center, so castling doesn't give any extra protection to the King

A sample game could be:

1-   e4     e11
2-   c4     [attacking f7 with the Bishop and the Queen!]

Notice that a Bishop, in an empty board, controls half of the squares! Example: a Bishop initially at f1, moving along the f1-a6 diagonal, would keep going along h7-a14 (=a0), then along h1-a8, and so on

This variant can lead to subvariants, or similar games:

Cylindrical Chess , the base subvariant, where the a and h columns are separated
Klein Chess , if the glueing between the 11th/12th lines (or -3rd/-2nd) was done after a switching, so that a11 would glue to h12, etc
