Colle System George Koltanowski Pdf Download

If you are looking for a simple and effective chess opening for White that does not require much memorization or preparation, you might want to consider the Colle System. This opening system was popularized by two Belgian chess masters, Edgard Colle and George Koltanowski, who used it with great success in many tournaments and matches. In this article, you will learn everything you need to know about the Colle System, including its main ideas, variations, benefits, challenges, and resources. You will also find out how to download a PDF file of the book by George Koltanowski on this opening system, which is one of the best and most comprehensive guides on the topic.


The Basics of the Colle System

The Colle System is a chess opening for White that is characterized by the following moves:

1.d4 d5 2.Nf3 Nf6 3.e3 e6 4.Bd3 c5 5.c3

The idea behind these moves is to create a solid and harmonious pawn structure, support the center with the pawns and the bishop, and prepare a kingside attack by castling and playing Ne5 and f4. The Colle System is very easy to learn and play, as White does not have to worry about many different responses from Black. White can play the same moves regardless of what Black does, as long as Black does not prevent e4 or c4. The Colle System is also very flexible, as White can choose different plans depending on the position, such as playing for a queenside expansion with b4 and a4, or exchanging the dark-squared bishops with Bd2 and Qe2.

The Koltanowski Variation

The Main Line

The most common and aggressive way to play the Colle System is to follow up with e4 after c3, creating a strong pawn center and opening up the position for the pieces. This is known as the Koltanowski Variation, named after George Koltanowski, who was one of the main experts and advocates of this line. The main line goes like this:

1.d4 d5 2.Nf3 Nf6 3.e3 e6 4.Bd3 c5 5.c3 Nc6 6.Nbd2 Bd6 7.O-O O-O 8.dxc5 Bxc5 9.e4

White has achieved his ideal setup, and now he can start his kingside attack with moves like e5, Re1, Nf1, Ng3, Bg5, Bc2, Qd3, etc. Black has to be careful not to fall into some typical traps and tactics in this position, such as losing a piece to Ng5 or Bxh7+, or getting checkmated on the h-file or the g-file. Here are some examples of how White can exploit Black's mistakes:

9...dxe4? 10.Nxe4 Nxe4 11.Bxe4 Qxd1? 12.Rxd1 f5? 13.Bxc6 bxc6 14.b4 Be7 15.Ne5 Bf6 16.Nxc6 Bb7 17.Na5 Be4 18.f3 Bc2 19.Rd2 Ba4 20.Bb2 Rfd8 21.Rxd8+ Rxd8 22.Nb7 Rd2 23.Rb1 Bc2 24.Rc1 Bd3 25.Ba1 Bh4? 26.g3 Bg5 27.f4 Be7 28.c4 Rxa2? 29.c5 Be4? 30.c6 Rg2+? 31.Kf1 Rxh2? 32.c7 Rh1+? 33.Ke2 Rxc1?? 34.Nd8?? Bxd8?? (34...Rxa1! would have saved Black) 35.cxd8=Q+ Kf7 36.Qd7+ Kg6 (36...Kf8 loses to Qxg7+) 37.Qxg7+ Kh5 (37...Kh6 loses to Qg5#) 38.Qg5#

This is a famous game between Koltanowski and Tartakower from London 1927, where White sacrificed two pieces for a devastating attack.

9...dxe4? (better is ...e5) 10.Nxe4 Nxe4 (better is ...Be7) 11.Bxe4 Qc7? (better is ...Qxd1) 12.Bxh7+! Kxh7 (or ...Kh8) 13.Ng5+ Kg6 (or ...Kg8) 14.Qg4 f5 (or ...e5) 15.Qh4 Bd7 (or ...Kf6) 16.Qh7+ Kf6 (or ...Kf6)17.Qh5 g 71b2f0854b
