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 New Book of Optical Illusions is a mind-bending collection of 150 of the most significant optical phenomena, loosely grouped into 33 chapters according to particular visual effect. An optical illusion has two elements. One is the perceived illusion, what you see. It may be merging lines, moving shapes or conflicting sizes. The other element is the scientific explanation or neuronal basis of the illusion. Here enters The New Book of Optical Illusions, which describes the latter - the science of an optical illusion. Concise text describes the history of the optical illusions and their origin. Some are ancient (like a 3D Roman mosaic in a 2nd-century BC home on Malta) and others are modern (like emoticons and street art). There are rarely seen phenomena, works by great illusionists, like M.C. Escher, and well-known illusions like the Impossible Triangle and the Albert Einstein/Marilyn Monroe portrait. Some of the illusions are: Seeing Things That Are Not There - Discovered on a BBC studio wall in the 1950s, this illusion involves shadows that seem to flit up and down along columns of stripes.Apparently the number of identical lines causes the brain to lose proper focus on what it is seeing. Flashes from the Corner of the Eye - The Scintillating Grid is a variation of the classic Hermann Grid first described in 1870. In this illusion, circles in an intersecting grid disappear and reappear elsewhere. It is a complex effect rooted in lateral inhibition, which increases the contrast between light and dark in the retina. Perfect for young and adult readers and enthusiasts of optical illusions, this is a great selection for circulating collections and retail customers.

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.
