The two extra pieces are the wizard (W) and the champion (C), which move as follows:
Wizard (W)Similar to a knight, it can *jump* in an L, but its L is 3x1 wheres a standard knight's L is 2x1. Additionally, it can move to diagonally adjacent squares.

All other rules are the same as standard chess, except for the addition initial move of pawns. In normal chess, pawns can make an initial move of 2 squares. In Omega Chess, pawns may move up to 3 squares. The En Passant capture has been augmented to allow en passant capture to either vacant square through which the pawn moved.
