Colle System: Zukertort Variation 5. b3
The variation is named after Johannes Hermann Zukertort, the first player to deminstrate the wonderful attacking potential of the white bishops lined up on the b1-h7 and b2-g7 diagonals. As we will see, there are many move orders by Black in the Colle-Zukertort, but white usually gets by with a single sequence: 1.d4, 2.e3, 3.Bd3, and 4.Nf3 - although in this book we will see a lot of other orders. The center is usually closed or semi-open in the Colle-Zukertort and this enables white to perform some elaborate maneuvers and execute long-range plans denied him when the center is open. Positional play is supreme. The chapters are: 1)Zukertort 5.b3 vs. Koltanowski 5.c3, 2)How White Wins, 3)How White Loses, 4)Common Strategic Mistakes, 5)Main Line Zukertort Vatiation 5.b3 Analysis.
