R173: 1->2 means: Find a "proofgame" in 16.0 moves, starting from position 
1,
and finishing with position 2. The upper two diagrams are for position 1, 
the
lower two are for position 2.

I'm sitting here alone in darkness, waiting to be free [ Solitude ]
Lonely and forlorn I'm crying                          [Candlemass]
I long for my time to come, death means just life
Please let me die in solitude
