The solution is in page 108 of the book: Endgame Virtuosity(A selection of 222 Israeli Chess studies). This is one of the books that I got as a prize for winning some of the israeli study competitions when the target was to compose long studies when the idea of the final position was known(for example in one of the competitions the rules said that the final move must be mate for white when white has only 2 pieces when one of them is a knight or a bishop or a pawn. The studies had to be good studies. This means that white has always one move to win in the main line(or to draw if this is the target). I do not remember the exact rules now but there was a rule that the first move cannot be a capture(or at least not a capture of more than a pawn). My studies had not artistic value so they cannot win other competitions(there were many captures but the first move was not a capture according to the rules). I used Genius3 to help me to compose the studies at that time when I always checked the next best move. I always tried for many hours to prove that my studies are not correct and I decided to believe that my studies are correct only after a failure to prove that they are not correct. I also tried to add moves backward with keeping the correctness of the studies. Genius3 helped me to outsearch my opponents who did not use a computer in seeing backward and I probably could not win the competitions without it. I won 4 books because 4 of my studies won first or second place. I found that the judge did not check the studies with a computer to check for errors and there were studies of other composers with errors. It is also not easy to know if a study is correct. This reason convinced me not to try to compose the 5th study and after 5 tournaments a new editor came and decided to stop these tournaments. Uri
