So they are probably >all correct. I believe that the solutions are correct but sometimes there is more than one winning move. I believe that in the 29th position Nf6+ instead of 29.Nxh6 is also winning. I think that 29.Nxh6 is the simplest way to win but not the only way to win. I am sure that in the 5th position f7+ is the simplest way to win but not the only way. White can also play Ke6 Ke8 f7+ Kf8 Kd6 and win. Every move is winning if you play later the move f7. Uri
