Being overwhelmed by the level of ingenuity and insight displayed by some of the contributors to this forum I have to take solace and refuge in using solving techniques which are more within my mental grasp. In preference I like to attempt and finish puzzles without using pencilled candidates or a computer; nor guessing, of course.
The following appeared in a recent French national newspaper which gave some satisfaction when I solved it in this manner:
1 X X X 2 4 5 X X
X X 8 X X X X X X
X 7 2 3 X X X 4 6
X X X X X X X X 9
X X X 4 X X 3 X X
X 1 X X 9 6 X X 2
X X 6 X X X X X X
X X X X 3 X 1 X 8
