Pawn peculiarities

Pawns capture differently from how they move (straight move, diagonal capture).
Pawns can move two squares straight ahead from their initial position, provided they are not blocked.
On the move immediately after such a double push, they can be captured en passant by another Pawn, -as if they had only moved 1 square ahead.
Pawns promote to another piece of choice (including King) when they reach last rank.

Castling

-A King that has not moved before can move two squares in the direction of a Rook that has not moved before, -in which case that Rook is moved to the square the King skipped over. -This is only allowed if all squares between King and Rook are empty. -

General rules

Capture is mandatory; if ay capture is possible, you cannot play a non-capture.
The game is won by the side that has no pieces left.
In other case of stalemate (no legal moves) the side with the smallest number of pieces wins.
Stalemate with an equal number of pieces is a draw.

Differences with FIDE

-Capture is mandatory. -The King is not special in any way, and can be captured like any other piece. -Hence the concept of 'check' does not exist. -Pawns can promote to King. -

Strategy issues

-The King is actually a good choice for a promotion piece, as it is not so easy for the opponent to feed a lot of material to a King. -
