Here are some ideas 

1mystery chess room on site  where you play vetted but unknown opponents -no name no rating 'til after the game-some sea swim races are handicapped after the race in a similar  way after the race.

2 a game where pawns can move forward and back

3  a game where you are allowed two moves in a row just once in a game

 4 game where you can take your own pieces if you wish.

5 a game where the king has the same mobility as the queen 

6 a game where bishops can change diagonal colour.

7 a game  where  pawns  move like one square knights 

8 a game where en passant applies everywhere 

 9.a game where rooks and bishops can both move diagonally horizontal vertical and also change diagonal colouors as suggested in #6

 good stuff'''''michuakahn''

 whatsa 1 square knight an why would you wanna take your own piece??

is a 1 square knight a piece that moves one square diagonally??

e.g. a1-b2

you would take your own piece if it was in the way of mating  or an advantageous move.
