This is\u003c\/p\u003e\u003cp\u003ethe moment in chess when basic mathematics breaks down, the moment when 3\u003c\/p\u003e\u003cp\u003ecounts equal to or even more than 5. So let us leave the mathematics aside and\u003c\/p\u003e\u003cp\u003etry to figure out why this simple calculation is so difficult to understand.\u003c\/p\u003e\u003cp\u003eThe answer is largely hidden in psychology, as the ninth World Champion, Tigran\u003c\/p\u003e\u003cp\u003ePetrosian, has often told us, as the man who brought this strategic-tactical chess\u003c\/p\u003e\u003cp\u003econcept to its first peak. Chess beginners were taught the value of pieces by\u003c\/p\u003e\u003cp\u003etheir teachers (parents, grandparents, perhaps at school or even later in the\u003c\/p\u003e\u003cp\u003ebeginners¿ sections of chess clubs). We explain the difference between piece\u003c\/p\u003e\u003cp\u003evalues to children in the simplest way possible, with the help of a unit of\u003c\/p\u003e\u003cp\u003emeasurement, and in chess those units are the pawns. They tell us that a rook\u003c\/p\u003e\u003cp\u003eis worth five pawns (units) and a knight and a bishop are worth about three\u003c\/p\u003e\u003cp\u003eeach. They also tell us to always be careful, especially during exchanges, to\u003c\/p\u003e\u003cp\u003eensure we take at least as much from our opponent as he or she took from us.\u003c\/p\u003e\u003cp\u003eSo, one rook at a time, perhaps for a bishop and a knight next to two pawns.\u003c\/p\u003e\u003cp\u003eThis ¿chess thinking¿ is done quickly and very strongly subconsciously in most,\u003c\/p\u003e\u003cp\u003eone could even say all. Therefore, when choosing moves, we will automatically\u003c\/p\u003e\u003cp\u003ereject unfavorable exchanges. But who trades a queen for a knight, a bishop for\u003c\/p\u003e\u003cp\u003ea pawn, and the like? We know from our own life experience that it is better to\u003c\/p\u003e\u003cp\u003ehave ten coins in our pocket than three, and I prefer three to one! This\u003c\/p\u003e\u003cp\u003epsychological barrier is the most difficult step in making the decision to\u003c\/p\u003e\u003cp\u003esacrifice. And so it is with the sacrifice of an exchange. Five for three, that\u003c\/p\u003e\u003cp\u003eis! Even five for four, if we get a pawn for the rook along with the knight or\u003c\/p\u003e\u003cp\u003ethe bishop. ¿I am not stupid,¿ you think. The Exchange Sacrifice Unleashed\u003c\/p\u003e\u003cp\u003ebrings different games or coaches try to explain this and that to us, we see\u003c\/p\u003e\u003cp\u003ethat a material advantage is not always something to celebrate about.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9789464201864\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Hardcover - 9789464201864","offer_id":47509314830661,"sku":"9789464201864","price":45.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/192ef42b-494f-466c-bc1c-57e88247b519.jpg?v=1779079023","url":"https:\/\/shop.autorenwelt.de\/en\/products\/the-exchange-sacrifice-unleashed-von-georg-mohr","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
