### A Paisley Problem

We're not returning today to the famed and troubled sixties, those times of tye-dyed shirts, paisley trousers, lava lamps, and much more which we shan't explore here. Instead, we're going back a full hundred years to the days of J. D. Janvier, who named the go-as-you-please opening 11-16 24-19 8-11 "The Paisley," without the slightest foreknowledge of peaceniks, Haight-Ashbury, or bell-bottoms. (We understand that Mr. Janvier was, much more prosaically, instead making reference to a town in Scotland.)

Here's some interesting published play in the Paisley:

 1 11-16 24-19 2. 8-11 22-18 3 4-8 18-14 4. 9x18 23x14 5 10x17 21x14 6. 16x23 27x18 7 12-16 28-24 8. 8-12 26-23 9 16-20 31-27 10. 6-9 25-21 11 1-6 29-25 12. 11-16 24-19 13 6-10 30-26 14. 10x17 21x14 15 7-10 14x7 16. 3x10 26-22 17 9-13 25-21 18. 2-6 18-15 19 10-14 22-18 20. 5-9 15-11 21 13-17 11-7 22. 17-22 7-2 23 22-26

And so we arrive at the following position.

BLACK

WHITE
White to Play and Win

W:W32,27,23,21,19,18,K2:B26,20,16,14,12,9,6.

Without turning to your books of published play, can you, fully on your own, find the White win? Even better, can you find Black's losing move in the play above, and correct it? To help in following the play, you can click here for an on-line animation.

If the effort frays your bell-bottoms or ruffles your Paisley trousers, clicking on Read More will bring you the answers quicker than you can light your lava lamp.
