Fwd: Re: [Retros] Two little SPG-challenges

[CAILLAUDM at aol.com]

Sorry Christoph, but your problem is cooked in 10.0 :
4.axb7 cxb2 5.bxa8=N bxa1=N 6.Nb6 Nb3 7.Nxc8 Nxd2 8.Nxe7 Nxf1 9.Kxf1 Kxe7  
10.Ke1 Ke8 (of course intention was 10...Nxb1 11.Nxb1)
not difficult for me to spot the cook, as I already worked on the subject :  
these switchback capturing are the "basic" cooks to avoid when constructing 
such  games.
 
Best,
 Michel 

Hello,

today I composed also an At-Home-Lazy  Spectators-SPG with Ceriani-Frolkin 
and Pronkin in 10.5 moves. The position  after 10.0 moves is C+ verified after 
few minutes by Natch. On the final  position Natch and Euclide are still 
working (I assume they will need not more  than a couple of hours) but as for 
Michel's SPG here is another chance for  human cookers to be faster.

Christoph Fieberg - SPG in 10.5 moves -  21.11.04 - C-
1n1qkbnr/p2p1ppp/8/8/8/8/2P1PPPP/1NBQK1NR b Kk - 0 11
SPG  10.5 (11+11)

Best regards,
Christoph
