1) "The pawn can still only move and capture in the forward direction
as it does in standard chess, however, the method of moving and
capturing is different. Instead of capturing diagonally, THE PAWN
MOVES DIAGONALLY and CAPTURES PIECES LATERALLY to either side..."

Okay, I understand this part. Now it gets tricky.

2) "If a piece, either opponent or friendly, occupies the square
diagonally in front of a pawn, the pawn is blocked and cannot move.
At the beginning of the game, the Forchess pawn can only advance by
capturing."

First he says you move diagonally, then he says that if the pawn is
blocked, it cannnot move. From this, I can only conclude that (from
#1 above), when the pawn moves, it moves to an EMPTY square.
However, due to the initial board layout, that simply cannot happen.

Initial layout:

K R N p p B R K
R Q B p p N Q R
B N - p p - B N
p p p p p p p p
p p p p p p p p
N B - p p - N B
R Q N p p B Q R
K R B p p N R K

What am I missing here?
