The Rose is called so because of its movement diagram. If you put in the middle of a 12x12 board and draw ALL the movement lines you will get the shape of a rose.

Actually a 13x13 board is necessary to show the full movement of the Rose. See Chess on a Really Big Board under 'Four Board Chess' for an ASCII diagram of the Rose's moves on a 16x16 board.

I prefer to use a Half-Rose (Ralph Betza's Halfling Rose) which makes at most 4 Knight leaps, travelling a half circle. Limiting the Rose to 6 successive Knight leaps, as in Irwell, can still produce strange results. I intend to present an example in my 12x12 variant.

Restricting the Rose to 6 leaps actually only rules out a null move. This is because the 7-leap move is only a lame duplication of the unblockable 1-leap move. It is the equivalent of restricting a Rook to 6 steps on a wraparound 8x8 board, or 14 steps on a Byzantine board.
