The nightmare positions can be found here: http://www.beepworld.de/members38/eigenmann/nightmare.htm [D] 6R1/4p3/B2p4/P7/4P3/p3n3/1n6/4K2k w - - This is a very deep position. Yace cannot find Rc8 in 10 hours. The analysis given by Walter: [Event "Pervakov 1984"] [Site "?"] [Date "????.??.??"] [Round "?"] [White "Nightmare Nr.025"] [Black "?"] [Result "*"] [Annotator "W.Eigenmann"] [SetUp "1"] [FEN "6R1/4p3/B2p4/P7/4P3/p3n3/1n6/4K2k w - - 0 1"] [PlyCount "15"] [Source "Walter Eigenman"] [SourceDate "2005.09.30"] 1. Rc8 $18 a2 (1... Kg2 2. Rc1 a2 3. Kd2 $18) 2. Rc1 a1=Q 3. Rxa1 Nc2+ 4. Kf2+ Nxa1 5. Bb5 Nd1+ 6. Kg3 Nc3 7. Bc6 Ne2+ 8. Kh4 $18 * Is the position at the end of the main line a forced win for white? [D] 8/4p3/2Bp4/P7/4P2K/8/4n3/n6k b - - 7 8 Yace seems not to be able to win from here with white. Regards, Dieter
