Chess960 was developed by Bobby Fischer and is played with a randomized first row and with the restriction that the
bishops always start on opposite colours and the king always starts between the rooks.
Castling is allowed as in normal chess, the king takes one step less than the rook if there are not an equal amount of spaces between them.
Gamestart for your game of chess960 is generated on a board that apart from the startup works as a normal chess board, which is to say that, for good or evil, you can move the pieces as you wish.
Update: New layout, and you can choose between "drag and drop" or "two-touch" movement.
