I think this first observation may come from the book move scores of Yace, they have to be ignored and were inititially meant only for my debugging. >Junior was also the first side to see that it is losing when yace saw it only >later. I don't want to doubt, that this was a lucky win of Yace. But I cannot totally follow your argumentation about the outsearching. Yace came out of book with about -3 at move 16. All the scores, you see before are more or less garbage. At the next move Junior also shows about -3 ( = +3 from Juniors side of view). The score continiously increases for white from both engines. For a few moves, Juniors score is significantly more in favor for white than Yace's score. Perhaps here, there was some outsearching. But it can also be, because of very unusual piece values of Yace (you suggested some of them) and unbalanced material in the PV. Later Yace's score is allways higher than Juniors score, and it also sees the mate just one move before Junior. I think not a clear outsearching. Regards, Dieter
