Henry Bird once explained how he came upon the opening system that bears his name: He has played relatively rarely during one six-year period of his life (this being 1873), and when he returned to the board for a match against another English master, Bird had no confidence in his opening repertoire. There was simply so much to know about his previously favorite 1 e4.
A Complete Opening System with 1.f4 and 2.b3. There are 20 important revisions and four complete games added to this 2nd edition 1996. This is a “left handed Dragon variation” where White has an extra tempo and Black cannot break open the Queen file. White will occupy the center from the flank with his 1.f4. This is to control “e5”. Laying in wait is the white Bishop on b2 to help with the K-side attack. “This opening retains life because of its unique features and creative possibilities and it’s a lot of fun to play.” – Soltis
