Here be a simple problem
For the keen directmate eye
White to move and win
In seven moves, Black shall die
However, I remember now a relative
Long ago did he begin to live
About a two decades or so
After the mid-nineteenth you know
We have the same theme, that’s to say
Can you give me relative’s father’s name?
Can you you also say our theme?
It’s chess problem related, quite a beautiful scheme
Give me the correct solution and the father’s name
And you’ll some points for playing this game!
It will help to solve first, that’s my call
Have great fun and good luck to all
For the theme, refer to the title!
