Thanks for your help - puzzle's now solved. I am still famialirising myself with X-Wing technique, therefore cannot recognise it very quickly. Are there any other tips to recognise here?
Thanks again.

Hi Kites - I don't think you're alone with your problem.

Firstly, row 9 of your puzzle layout is unclear. Using your row 1 as an example, I personally find the following format easier to understand:

[1][568][4] [2][56][7] [3568][36][9]

As for tips to identify an X-Wing pattern, if you haven't already done this, download the "Simple Sudoku" free program on the following site :

http://angusj.com/sudoku/hints.php

This program has many features including "filtering" of candidates (pencil marks) so that, for example, all the candidate 1's are isolated and shown for each cell where this candidate appears - or for any other candidate number selected. This enables easier detection of an X-Wing pattern.

Hi Bonsai Cec,
Thanks for the tips.
Re your suggestion of how to layout a puzzle, no problem. Though, I have been asked, at different times, different layouts. Shall try and make a better job of it next time, and no doubt, there will be a next time...
