16 moves minimum.

When solving, make sure you never move the Queen more than three times, or the Rook more than 2 times, etc. Also, because white only has 16 moves total, all moves you consider must directly serve towards getting a piece to its diagrammed position. - 15 Jul '06 21:47Now I've been trying this with pen and paper, no board other than one sudoku grid (they now have a point).

As already stated white has only the sixteen moves. I thought the rook has to be in place quite quickly as it'll interfere with the black moves (2R, 2 each B, 2Q, 4P for a total twelve, allowing three 'waiting' moves). The black P must be on b5 to be captured. To allow the knights in position before the f,g and h pawns advance, the Q and Bs can wait on the third rank. Whites knight on b1 moves first to cover the black squared bishop which is released first. The black Q needs to be in position on e3 before d4 is played, meaning the black squared bishop is last to develop.

Anyway, my solution:

1) a4 b5

2) axb5 Bb7

3) Ra6 Bf3

4) Rf6 c6

5) Nc3 Qb6

6) Ne4 Qe3

7) d4 e6

8) Qd2 Bd6

9) Qa5 Bg3

10) Qb6 a5

11) Nh3 Ra7

12) Nf4 Rc7

13) h3 Bh2

14) g3 Bg2

15) f3 Qf2+

Good use of logic. That's the intended solution.*Originally posted by Peakite***Now I've been trying this with pen and paper, no board other than one sudoku grid (they now have a point).**
