Nicely spotted :). I haven't got a clue what my original 281 path was on this one :x.Can't see anywhere you can really lose 12 moves on it in one go; and I can't see an alternate path to 281 :\
Was two off for a long time. As usual, I'd figured out the main tricks and missing two simple moves.Great shortcuts though, I'd have given this 7 points rather than 6, myself.
