XuanxuanQijingProblem135/Solution

f3etoiles Here is my solution, but I have not much merit, as it is similar (the start, actually) to a famous loose ladder problem by Hayashi Gembi...

Solution 1 : first, reduction to one eye with 2 liberties in sente  

Solution 2 : now, a surprising first line sequence  

(note : the order of move at the start is essential, as if Black is allowed to play at 1, it is alive)
