Winning was a surprise: I was 4 off, found a 2 steps saver, went up to target to verify it had in deed saved 2 steps and... won! 0-0
3 possible explanations:
1) The 2 steps saver was a 4 steps saver that I failed to see.
2) I did a another 2 steps saver later without noticing.
3) Magic.
I tend for 1) or 2). Will check later. LOL
