Böcker av Georg Mohr

Dragoljub Velimirovic was a former Yugoslav - Serbian, chess grandmaster whose international career was handicapped by political intrigues and his outspoken temperament. During the heyday of the USSR as the greatest national chess power, the former Yugoslavia was capable of running the Soviet Union a good second. Dragoljub Velimirovic posed a real threat to the men from Moscow. Velimirovic was born in 1942 to a prominent family from Valjevo, in the former Yugoslavia. He was introduced to chess at the age of seven by his mother, Jovanka Velimirovic, one of Yugoslavia's leading female chess players. He died at the age 72, being one of the last players to develop a system or strategy that is so inventive it bears its creator's name. It is a feat that is unlikely to be repeated in the modern era, when computer-based games and databases so thoroughly dominate competition that it is almost impossible to come up with something new. That does not mean that players were more talented or courageous in the decades when Velimirovic was in his prime. Velimirovic, who became a grandmaster in 1973, was never among the 20 top-ranked players in the world. And that was when there were only 200 or so grandmasters; today, there are about 2,400.

The book you have just started reading isabout a very interesting and difficult concept: the exchange sacrifice. This isthe moment in chess when basic mathematics breaks down, the moment when 3counts equal to or even more than 5. So let us leave the mathematics aside andtry to figure out why this simple calculation is so difficult to understand.The answer is largely hidden in psychology, as the ninth World Champion, TigranPetrosian, has often told us, as the man who brought this strategic-tactical chessconcept to its first peak. Chess beginners were taught the value of pieces bytheir teachers (parents, grandparents, perhaps at school or even later in thebeginners¿ sections of chess clubs). We explain the difference between piecevalues to children in the simplest way possible, with the help of a unit ofmeasurement, and in chess those units are the pawns. They tell us that a rookis worth five pawns (units) and a knight and a bishop are worth about threeeach. They also tell us to always be careful, especially during exchanges, toensure we take at least as much from our opponent as he or she took from us.So, one rook at a time, perhaps for a bishop and a knight next to two pawns.This ¿chess thinking¿ is done quickly and very strongly subconsciously in most,one could even say all. Therefore, when choosing moves, we will automaticallyreject unfavorable exchanges. But who trades a queen for a knight, a bishop fora pawn, and the like? We know from our own life experience that it is better tohave ten coins in our pocket than three, and I prefer three to one! Thispsychological barrier is the most difficult step in making the decision tosacrifice. And so it is with the sacrifice of an exchange. Five for three, thatis! Even five for four, if we get a pawn for the rook along with the knight orthe bishop. ¿I am not stupid,¿ you think. The Exchange Sacrifice Unleashedbrings different games or coaches try to explain this and that to us, we seethat a material advantage is not always something to celebrate about.

Der Kommentar zur Kritik der reinen Vernunft bietet eine textnahe Erschließung der zentralen Begriffe, Thesen und Argumentationsgänge von Kants Hauptwerk auf aktuellem Forschungsstand. Es ist der erste Kommentar zur KrV, der den gesamten Text in der Fassung der ersten und zweiten Auflage gleichmäßig und lückenlos berücksichtigt. Davon profitieren vor allem die "Transzendentale Dialektik" und die "Methodenlehre", die in früheren Gesamtkommentaren meist nicht hinreichend berücksichtigt worden sind. Die Beiträge wurden nach einheitlichen Richtlinien verfasst, wobei unterschiedliche Herangehensweisen und Interpretationsansätze zur Geltung kommen. Um dem Leser dieses Kommentars die Orientierung zu erleichtern, ist jeder Beitrag in drei bzw. vier Teile untergliedert: Der erste Teil behandelt die Stellung und Funktion des kommentierten Textabschnitts in der KrV, der zweite Teil gibt einen Überblick über Inhalt und Aufbau des Abschnitts, der dritte Teil enthält den eigentlichen Textkommentar. Wo dies sinnvoll erschien, wurden in einem vierten Teil wichtige Interpretationsfragen angesprochen. Hinweise auf weiterführende Spezialliteratur am Ende eines jeden Beitrags, eine Auswahlbibliographie zu Kant und zur Kritik der reinen Vernunft sowie ein Namen- und ein Sachregister machen den Band zu einem komfortablen Arbeitsmittel für den Benutzer. Die vorliegende zweite Auflage trägt der Tatsache Rechnung, dass der Band mittlerweile als Standardwerk der Kant-Forschung gilt.
