This was played on the fifth round of a tournament that was played at Salo in November, 2006. On the first three rounds of this tournament I lost all my games. On my fourth round game I was able to break my losing streak finally, but sadly this was only a short anomaly, because on this fifth round I suffered another loss. Having scored only one point in five games, I ended up on last place in the final standings of group D. This disastrous tournament meant that my rating dropped 78 points because of these five games. My opponent ended up being third last in the group due to this win. He managed to get 2 wins in 5 games and lost 3 games. I have added one more puzzle to mate in two, three, nine, ten and twelve pages.
