JT Onkoud 50 theme

H#2-7 theme. In all phases, all moves with the same move number are played on the same line. The line can be a file, a rank, or a diagonal. Two or more solutions are required. The idea can be doubled.

Note: In Helpmate Analyzer, due to the large number of random problems matching theme conditions, at least three phases for the theme are required.
