Flatschach

Raumschach is the classic 3D Chess.

Flatschach is a tongue-in-cheek exploration of what a two-dimensional version of Raumschach might be like. Take the 5 5x5 boards of Raumschach, place them side by side to form a 5x25 board, give each piece the movement capabilities that it would have on the center cell of the 3D board, and you have Flatschach.

Opening setup:

As stated, pieces in Flatschach move as they would if they occupied the center cell in Raumschach.

  • Pawns move 1 forward, as in Chess, or leap 5 forward. They capture as pawns or as (1,6) leapers.
  • Kings move as Chess kings or as leapers: (0,4), (0,5), (0,6), (1,4), (1,5), (1,6).
  • Rooks move as short rooks (R2) or as (0,5) leaper-riders.
  • Bishops move as short bishops (B2), as (0,6) leapers, or as (0,4) and (1,5) leaper-riders.
  • Knights move as Chess knights or as (0,3), (0,7), (0,9), (0,11), (1,10), or (2,5) leapers.
  • Unicorns move as (1,4) or (1,6) leaper-riders.
  • Queens move as Rooks, Bishops, or Unicorns.

Raumschach has flaws. Many think the Unicorn is too weak and the King is too mobile. I think the diagrams above illustrate why.
