The Zagreb Variation, 6.g3, is a relatively new way of fighting the Najdorf Sicilian. It was First introduced in the late 20s, but it never really became Popular until the 50s. Unlike the main lines, the Zagreb variation is strategic in nature. Its aim is to fight Black in the center by increasing control over the d5 square. In this video, I've tried to explain the strategic ideas behind the move g3, to make sure you could play positions coming out of the Zagreb Najdorf even if you're out of book. I've also gone over all the theory and shown several early games in the variation that have historical significance.
The move 6.g3 is known as the Zagreb variation or the fianchetto. Apparently the name Zagreb (which is my home town) began being used in the 50s and 60s when many Yugoslavian players began using g3 as their anti-Najdorf weapon.
The Najdorf Variation of the Sicilian Defense (B90 - B99) is one of the sharpest, most heavily analyzed and most fun openings in all of chess. It can lead to completely mental positions which not many humans can completely understand. White has 11 (!) different ways of fighting the Najdorf and I will cover each in a separate video.
