To be sincere, I thought even to find my old version to see if somehow it was not mistake in my last change. Everything is possible. I remember few bugs that were found only few years after coming into my code. >05:01 WM11 11 Nxg5+ Qfxg5 Qce4+ Nf5 Qxh5+ Qxh5 Qexf5+ Qhxf5 Qh4+ Qh5 Qxh5+ Qxh5 >Rxh5+ Qfh6 Rxh6+ Kxh6 Qg5+ Kh7 Qh5+ Qh6 Qdxh6# > >Don't look at the time, the job ran in the background ... so that means back to >the drawing board for me. > >>Your time is good.

See you again next year, after I've finally caught this >bug of mine ... hmmm, wonder if I could hire Heiner for that. :) You start speaking to me in Italian (buena sera). Never mind. Before coming to Canada I was in Italy and liked it very much. It is the place where for the first time in my life I worked as interpreter (Russian-Italian) in one refugee agency. Make him (Heiner) move more quickly. I also wait for his next graphics oriented version. It is the best possible reference mate solving program that I could dream about. Leonid. >Paul
