On the traces of Giegold (1)

I have always been fascinated by tricky chess problems with hidden maneuvers, piece sacrifices, etc. Therefore, the works of problemists like Sam Loyd and Fritz Giegold had quite some influence on my composing style and i created several nice puzzles surely reminding solvers of them. Every now and then, I'll show you some of my works. Here are the first two:

  1Gerson Berlinger  
32er 3,4/1990
[1N6/3p4/1P1P4/3P4/4Pk1B/5P2/4K3/R7]
  #4(9+2)  

  2Gerson Berlinger  
32er 11,12/1989
[8/8/8/8/pPk5/K1b5/p3p3/3n4]
  h=6(2+6)  

Solutions:
1 1. Ra8! Ke5 2. Ke3 Kxd6 3. Nxd7 Kxd7 4. Rd8#
The key move only makes sense, and only then you'll actually consider it, until you've (fore)seen the whole course of action. Additionally, those quiet White moves add to the difficulty of the problem.
2 1. axb3 e.p. Ka4 2. Kd3 Kb5 3. Kc2 Kc4 4. Kb1 Kd3 5. Ba1 Kxe2 6. b2 Kxd1=
Admittedly, help(stale)mates with retro content are nothing special and not really unusual. Still, you may not be aware immediately that there is such a possibility. Especially in this case, where you have to capture the only white piece (apart from the king) in order to achieve the aim.
