1.f4 is the Bird opening. It was played by Henry Bird. He wanted to leave the mainstream and create new original positions. He liked a setup with b3 and Bb2.
The Polar Bear System (PBS) was played with the same intention. To leave the trodden theory paths and enter new undiscovered terrain. The system starts with a fianchetto of the Kings bishop after 1.f4, dS. PBS players want to enter interesting and original positions where it is difficult for Black to play for a flatequality.
The book is for club players but also professionals can get inspiration.
Grandmaster in chess, Henrik Danielsen
The Polar Bear is a system for players who like interesting and original positions without being too concerned about proving a theoretical advantage. In many of the variations the positional themes and plans are of more importance than actual move orders. Our system starts after 1.f4 (the Bird opening) and then fianchetto of the Kings, Bishop. A mirror image of the Leningrad Dutch. The system is a hybrid combination of the strategically complex King's Indian and Dutch defences with reversed colours. By playing the Polar Bear, we make it difficult for Black to play for a flat equality. We want a potent, fighting game with a "full board". I do not understand why the Dutchdefence 1.d4, f5 is considered an aggressive opening, but the Bird 1.f4, d5 not. It doesn't seem logical. I will let the veracities speak for themselves and show you a strong and fascinating system.
"One man's trash is another man's treasure". I have spent many years developing the Polar Bear System. I know it inside out. However I have to warn you: The Polar Bear System is difficult to handle! Indeed I have turned every stone in the system. Since there is no theory of importance, I had to work hard. I read everything about the Dutch defence and used the ideas with reversed colours. Therefore the theory in this book, was mainly created through my own games and analysis. I have played thousands of games online, trying to discover the very essences of the system.
Many of the games were of poor quality, so I had to select the best ideas. And turn them into a repertoire book. Omitting lines in which I do not believe. The project turned out to be too substantial for one book, so I had to split it up in two books.
I would like to thank my partner Arora Hronn Skuladottir, for helping me turn the Polar Bear System into a book. She is a multitasker! Computer typesetting, creating the cover, proof reading, photos and final preparation. Without her help, it would have been difficult. evertheless here is complete book of the Polar Bear System, with a full covering of 1.f4, d5.
