ARGH!!! (brain-teaser)

[Mao]

So I'm playing Space Rangers 2 and for the life of me I can't figure out this quest. It's much more puzzle-oriented (chess-like) actually. Here's the deal: There are seven spaces in a row and six checkers. Three are black and three are white. Checkers can jump over each other, or just more space. The point is to get it so that the black checks and the white checkers reverse positions. You have exactly 15 moves to do this in.

Here's what the set generally looks like:

| W | W | W | N | B | B | B |

W = white checkers
B = black checkers

For example, the following are possibilities for the first move:

| W | W | N | W | B | B | B |

| W | N | W | W | B | B | B |

| W | W | W | B | N | B | B |

| W | W | W | B | B | N | B |

If you can do it, wanna also show me the fifteen moves? This is a nice brain-teaser if you so desire
