(10 years ago) Very interesting, with lots of possible paths. 18 tries for lucky me. :)
*******************************************
EDIT 2023, 9th May: this time I wasn't so ''lucky'', took me 40 tries, on the nose (in several sessions). For the most part I was looking for the last 2 moves, with the wrong assumption, where I was loosing them. :)
Gosh, this was truly misleading. :)) First, I was on the right path, but didn't do it right. Then I was on the wrong path, trying to optimize, LOL. Finally I came back to my first path and got it first try. :))
