I remained a long time stuck 2 off and as usual when it's clear that it's optimized and the route must be different, I have it hard to force my mind to reset and build up something new. However, once I did that, I won straight after 3 tries... LOL
The mind reset is the hard step... :D
I will never understand why this one and not another, but that board was easy to me. I saw the puzzle, understood the problem, understood what configuration will solve it, and build it up. Once clear on routing, optimization follows rapidly. Happy me!
At first I was a bit afraid of having a 2 off, because it's a pain in boards with lot of liberty to move around. But I was lucky to solve it fast without a 2 off.
