The theme of helpmate section of the BCPS 2012 Tourney dedicated to Olympic games in London 2012 attract my attention, because was non standard: Part (a) H#n, where n=0.5; 1; 1.5; 2 and so on. Any kind of twinning leads to Part (b) H#(n+2). The sequence may be continued as far as desired, increasing leght by 2 each time: part (c) H#(n+4), part (d) H#(n+6) and so on. Each part must have a single solution.

Here the theme is realized with four thematic solutions (probably a task!), four white Queen promotions and model mates in white minimal form and interesting twins with rotations. The play is in all directions of the board! This was one of the most difficult helpmate which I composed and it took me more than 6-7 months. (Author)
