It is sometimes said that winning a won game is the hardest thing in chess. Not strictly speaking true but I managed to drum up some support for this theory at the 4NCL and Bundesliga that followed. In the positions below particularly bearing in mind the fairly healthy clock lead in several of them you might expect to make more than 2/4.
As you may have noticed actually I was rather lucky to make that, as the one position I did convert was off the crossbar.
