I have a personal "trick" when I'm stuck and out of idea. I try something crazy, that I know is wrong, but just to force new situations that will give me new perspective(s). On that one, I was 2 off and out of ideas, so I did my usual trick by pushing the block in the opposite direction of the 2 off route and this simple - apparently not plausible - side change got me to winning... Although I was certain it would be longer... ROFL
Can't believe I FINALLY beat this. I see it's 22 days, since it was published and I was trying often (not every day, though). Almost gave up, had NO ideas, left. Today, it somehow ''weakened'', and I managed to get through in 38 steps. Nobody DARE to change the existing record, or I will cry till the rest of my days.
