What is the minimum number of strokes to reproduce the drawing below without lifting up the pencil from the paper (no tricks at all), and without passing over a line segment (or part of it) already drawn? You may begin and end wherever you like, and line segments may cross each other, but only as intersections.

Note: a new stroke occurs when a line type ceased because you have to stop and change direction.

(In reply to re(2): No Subject = Solution by Sir Percivale)

I didnīt say also that 14 is the minimum. All that I said is that your solution presents 14 strokes. Only this.
