With 10 opening articles, ChessBase Magazine #210 covers the usual broad spectrum of variations: From the English Opening á la Caruana (1.c4 e5 2.g3 f5 3.Bg2 Be7) or the Sicilian O'Kelly Variation (1.e4 c5 2.Nc3 a6 Part I: 3.d4/3.c3) to the Catalan (with the unconventional move 7.Qd2). In his contribution, Patrick Zelbel provides a concept against the Modern Defence (1.e4 g6 2.d4 Bg7 3.Nc3 d6 4.Be3), which is especially popular at club level and in which the move 4...a6 has become firmly established thanks to the Swedish GM Tiger Hillarp Persson. Our author begins the hunt for the tiger with 5.g4!? and thus makes it immediately clear where the journey is heading. "If Black plays the most natural moves, they easily finds themself in trouble", Zelbel writes in his conclusion. So you should definitely give this a try. Take a look!
