Oczywiście, człowiek ma ten sam problem, ale w przeciwieństwie do maszyny, aby coś dostrzec, nie musi liczyć wszystkiego, co do tego prowadzi, poza tym doświadczenie, wiedza i zdolność rozpoznawania schematów pozwalają mu często podejmować najlepsze decyzje bez głębokiego liczenia wariantów. <br /> <br />Człowiek ma zdolność rozpoznawania schematów i dopasowywania ich do sytuacji na szachownicy. Człowiek będzie wiedział, zarówno na podstawie wiedzy dostępnej w literaturze szachowej, jak i własnego doświadczenia, czy w danej pozycji różnopolowe gońce dają większe szanse na atak czy raczej na remis albo czy w dłuższej perspektywie, na przykład w możliwej do uzyskania końcówce, goniec będzie słabszy od skoczka przeciwnika czy silniejszy. Silniki taką wiedzę mają w szczątkowej postaci. <br />Sprawa jeszcze bardziej komplikuje się w przypadku debiutów i końcówek. <br /> <br />Liczba możliwych posunięć i skomplikowanie pozycji powstających po zaledwie kilku początkowych ruchach sprawiają, że ocena pozycji przez program musi być płytka, a wiedza debiutowa powstała przez ostatnich kilkaset lat jest ogromna. Dlatego programy na początku partii standardowo korzystają z przygotowanych przez ludzi książek debiutowych, bez nich radzą sobie nie najlepiej. Oczywiście, silny szachista musi mieć tę wiedzę w głowie: często gracze pierwszych 10, 15 albo więcej posunięć wykonują bardzo szybko, bo albo korzystają z dostępnej wiedzy (nazywanej także teorią), albo grają przygotowane przez siebie, nowe warianty. <br /> <br /><a href="http://szacharnia.blogspot.com/" target="_blank">http://szacharnia.blogspot.com/</a> <br /> <br /> <br /><span style="font-weight: bold">Nauka matowania Hetmanem!</span> <br /> <br />Autor : <span style="font-weight: bold">Andrej N.
