This is\nthe moment in chess when basic mathematics breaks down, the moment when 3\ncounts equal to or even more than 5. So let us leave the mathematics aside and\ntry to figure out why this simple calculation is so difficult to understand.\nThe answer is largely hidden in psychology, as the ninth World Champion, Tigran\nPetrosian, has often told us, as the man who brought this strategic-tactical chess\nconcept to its first peak. Chess beginners were taught the value of pieces by\ntheir teachers (parents, grandparents, perhaps at school or even later in the\nbeginners’ sections of chess clubs). We explain the difference between piece\nvalues to children in the simplest way possible, with the help of a unit of\nmeasurement, and in chess those units are the pawns. They tell us that a rook\nis worth five pawns (units) and a knight and a bishop are worth about three\neach. They also tell us to always be careful, especially during exchanges, to\nensure we take at least as much from our opponent as he or she took from us.\nSo, one rook at a time, perhaps for a bishop and a knight next to two pawns.\nThis “chess thinking” is done quickly and very strongly subconsciously in most,\none could even say all. Therefore, when choosing moves, we will automatically\nreject unfavorable exchanges. But who trades a queen for a knight, a bishop for\na pawn, and the like? We know from our own life experience that it is better to\nhave ten coins in our pocket than three, and I prefer three to one! This\npsychological barrier is the most difficult step in making the decision to\nsacrifice. And so it is with the sacrifice of an exchange. Five for three, that\nis! Even five for four, if we get a pawn for the rook along with the knight or\nthe bishop. “I am not stupid,” you think. The Exchange Sacrifice Unleashed\nbrings different games or coaches try to explain this and that to us, we see\nthat a material advantage is not always something to celebrate about.\u003c\/p\u003e","brand":"Thinkers Publishing","offers":[{"title":"Default Title","offer_id":49602082537816,"sku":"9789464201697","price":39.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/1295\/4195\/files\/9789464201697.jpg?v=1765878338","url":"https:\/\/agendabookshop.com\/products\/the-exchange-sacrifice-unleashed-power-of-middlegame-knowledge-1","provider":"Agenda Bookshop","version":"1.0","type":"link"}
