was born in 1968 in Frankfurt-am-Main and took his first steps in club chess at the early age of 14 (for the Langenselbold chess club). In addition to his chess apprenticeship, he also studied for the profession of physics laboratory technician. In the middle of the 90s he decided on a change of career and became a stock exchange trader. At this time he became regional champion (Main-Vogelsberg region). This was followed by jobs such as car deliverer and data compiler. Parallel to all of this, he produced his CDs for ChessBase and the tactical exercises for the CD "World Champion Tal". In Schlößner's opinion: "How can someone like I am (a weak player compared to the other ChessBase authors with my Elo of just over 2000) come up with several, even successful CDs? Well, when it comes to tactical exercises, you know what you have to do: there is a specific task and all you have to do is to land the k-o punch. But every player knows that there is nothing which is as difficult as actually winning a won position. Even the best players in the world are confronted with this problem (admittedly at a different level). And against modern chess programs things are even one level harder than against a human being. You can soon get very frustrated when playing against a machine. My CDs allow you not only to train against Fritz, but even to win on some occasions. All the programs have to learn now is how "to get annoyed"..."
