Millennium 3D Chess starting position

Millennium 3D Chess is a chess variant created by William L. D'Agostino in 2001 that employs three vertically stacked 8×8 boards, with each player controlling a standard set of chess pieces.[1][2] The inventor describes his objective as "extending the traditional chess game into a multilevel environment without distorting the basic game."

The 8×8×3 geometry is a popular one with 3D chess inventors, and several proprietary versions exist. D'Agostino has made available a free, downloadable set of rules as well as a small but growing online library of recorded games.

## Move notation

The three board levels are denoted 1 (White's board), 2 (the middle board), and 3 (Black's board). Moves are recorded in the same manner as chess, using algebraic notation, with the only difference that each square is prefaced by its level number.

For example, in standard chess, White's king starts on square e1 and Black's king starts on square e8. In Millennium 3D Chess, White's king starts on 1e1 and Black's king starts on 3e8. (And so on.)
