Bring up Genius!

Well before having children, Laszlo Polgar wrote Bring Up Genius! where he explained “Genius equals work and fortunate circumstances” and “Geniuses are made, not born”. Laszlo went on to prove his theory by raising three exceptional female chess players - Susan Polgar achieved the GM title at 21, Judit Polgar at 15, and sister Sofia is a strong IM. While Laszlo certainly maintains an above-average IQ, biological predisposition alone cannot explain these results. The Polgar sisters developed their impressive chess skills in a favorable environment conducive to very diligent, hard work.
