Today's puzzle: as Bud's...

Hi Alfred,
sorry to have missed your messages two days before. I guess you have got relevant responses from Wombat. You could also read Internet pages such as e.g. http://www.sudoklue.com/help/techniques.html
Query 'BUG sudoku' in your search engine.
BTW, there was also a nice deadly pattern to find in yesterday's tough puzzle
Best regards. cenoman
