Product Review

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,d5. PBS
players want to enter interesting and original positions where it is
difficult for Black to play for a flat equality.
The book is for club players but also professionals can get inspiration.
Grandmaster in chess.
