I'll post my own WSC report on my blog (motris.livejournal.com) soon and link to it here when I do.
The WSC in Prague was a very well run and increasingly tight competition with a lot of talented sudokuists that were not at the first WSC. The Times has the "final" puzzle in print today, but as the playoff rounds were split into two puzzles each, the puzzle that actually determined the championship was a tough diagonal puzzle, with me finishing in ~ 8 minutes and runner-up Yuhei Kusui of Japan having 27 cells left to fill when the 10 minute limit ran up. As noted in the report, I took extra caution in solving the last puzzle as making a huge mistake and not finishing it was the only way I'd lose, so the "five minute" standard is a bit generous.
I'll post the diagonal puzzle here if it is not elsewhere in the next day but first I need to find a copy. I also hope the video of all the solvers during the finals comes up soon as I think it is really compelling to watch how the best sudoku solvers approach some of these puzzles. I'm pleased to say, throughout the whole competition, I never ran into a moment I felt guessing and checking would be advantageous to logic, which was my one regret on the final puzzle last year.
