The winner
![:lms:](./images/smilies/medal_light_s.png)
It is strange that has not been presented any solution with a pulley, I present the own variant.
The dark solution has been sent only one, its author markmadras. A classic Jackhammer as always is effective, but result 2488. The dark medal is not awarded to anybody, but the author presents the own solution out of a rating.
Thanks all and congratulations to the winner!
