O.K., I guess this was too hard. Here, I'll make the first diagram into four puzzles (one for each line). Obviously they all have the same key move.

why did u make 4 same puzzles, but different boards. WASTE OF TIME MUCH

The easiest way is to do the alternate variations on the actual puzzle. They don't show in the move list unless the person solves the puzzle or gives up.
You cannot make one puzzle contain multiple variations in the puzzle itself. I wanted people to try to figure out how to solve each variation separately, not just read about them all after solving one.
The following is the first published solution to the Babson Task that did not require promoted pieces and whose key is not a capture. The position is also legal and the key is thematic. If you cannot solve this (I find it an extremely difficult problem), your task will be aided greatly by looking up "Babson Task."
Here is another problem related to the Babson Task, but somewhat different. The position is illegal and cluttered, but the puzzle is still remarkable.
When you give your solution, post the key and all lines at least to the second move. Otherwise it is not really a complete solution.
