Such a nice GM. Kind of fun! :))
(It feels like there might be less than 188, but I can't find it.)
EDIT ( about 2 hours later) : I see it turned SGM. I was looking for ways to save more steps, but haven't found anything (but longer variations).
I hope people won't take this to editor, cause it then loses difficulty (which does not seem right).
I find it a very good level and fun to search for solution.
