Perhaps I should have said, the article also states, that the Hiarcs 7.32 search was prone to exploding at plies of 10 or over. If the change in the shape of the search tree has fixed this problem then it should help with long time controls. Anyway, I suppose we will find out when it is included in the SSDF ratings and we can see the difference between HIarcs 7.32 and Hiarcs 8. IA > >Uri
