Jump to navigationA 'Maid of the Mill' Surprise

Above, a group of Morris Dancers are performing and one dance often performed by such groups is Maid of the Mill. While the dance is itself well known, Maid of the Mill spans many genres: dance, art, literature ... and draughts.
In our ongoing serialized story, Three Move Opening: A Checker Romance, our protagonist made an unfortunately timed reference to the Maid of the Mill opening. Today, we'd like to offer something quite substantial in the play of that opening.
The following is based on the 15th game of the 2014 World Championship Go As You Please match between Sergio Scarpetta (Black) and Ron King (White). The game, as played, ended in a draw, but there was an interesting winning possibility for Black.
| 1. | 11-15 | 22-17 |
| 2. | 8-11 | 17-13 |
| 3. | 15-18 |
Forms Maid of the Mill.
| 3. | ... | 23x14 |
| 4. | 9x18 | 21-17 |
| 5. | 10-15 | 25-21 |
24-20 is definitely better, but it isn't clear that this move loses.
| 6. | 4-8 | 26-23 |
| 7. | 18-22 | 24-19 |
| 8. | 15x24 | 28x19 |
| 9. | 11-16 |
Back into the KingsRow opening book with a pull for Black, but not clearly a win.
| 9. | ... | 27-24 |
| 10. | 8-11 | 24-20 |
| 11. | 7-10 | 32-28 |
| 12. | 3-7 | 28-24 |
| 13. | 11-15 | 20x11 |
| 14. | 7x16 | 24-20 |
23-18 also draws.
| 15. | 15x24 | 20x11 |
| 16. | 12-16 | 11-8 |
Loses; 23-18 should draw.

Mr. Scarpetta didn't find the win. Can you? We realize that's a lot to ask, and in fact it's a very difficult problem, but the solution is as surprising as it's good, and we think that any effort you put into this problem will be amply repaid. So do try it, and then click on Read More to see the answer.
Solution
The following play is rather long, with many variations possible; use your computer to explore it further. But give yourself full credit if you found the surprising key first move.
| 17. | 24-27! |
An amazing move.
| 17. | ... | 31x24 |
| 18. | 16-20 | 24-19 |
| 19. | 10-14 | 17x10 |

| 34. | 1-5 | 16-20 |
| 35. | 26-22 | 20-24 |
| 36. | 22-18 | 11-16 |
| 37. | 18-14 | 16-20 |
| 38. | 13-17 | 24-28 |
Seeking the double corner.
| 39. | 17-22 | 20-16 |
| 40. | 5-9 | 28-24 |
| 41. | 23-27 | 24-28 |
| 42. | 22-26 | 30x23 |
| 43. | 27x18 | 16-20 |
| 44. | 9-13 | 20-16 |
| 45. | 13-17 | 28-24 |
| 46. | 17-22 | 24-19 |
Not 24-28 31-27; a subtle technique, well worth knowing, to deny White the double corner.
| 47. | 22-26 | 16-11 |
| 48. | 26-30 | 19-16 |
| 49. | 30-26 | 16-12 |
