Recently someone (Mike Byrne?) started to post the Nolot positions one by one and I gave them to Gerrit Reubold's Bringer, that could solve the first 3 positions posted, though #3 needed clearly more than one hour (#1 about an hour, #2 about a minute). Here is Bringer on Nolot #3 (PIV3.2HT) 5:45:30.6 (20/58) 9544021276 0.27 1.Lxg5 Lxg5 2.O-O O-O 3.Dc2 Le3+ 4.Kh1 h5 5.Tae1 Lh6 9:47:56.9 (20/59) 16404396553 0.28 1.Sxg5 (Mat=335,50=0) 22:28:32.9 (21/59) 38044449889 0.68 1.Sxg5 (Mat=335,50=0) 32:28:39.6 (21/59) 55496131033 0.83 1.Sxg5 Lxd1 2.Sxe6 Dc8 3.Sxg7+ Kf7 4.Lh6 Lg4 5.O-O+ (Mat=-465,50=4) As he stopped after position 3 I didn't try the other ones yet.
