The Bird Opening is above all a lovely surprise weapon. Moreover it is perfectly suited to those who play the Dutch, since after 1.f4 d5 one can play one’s favourite opening with an extra tempo. For the Powerbook an Elo threshold of 2300 was set. Thus 53 000 games from the Engine Room of Playchess found their way into the database. To those were added more than 4000 games played by human beings.

It is almost always the case that the Dutch is being played with an extra tempo, be it with e3 followed by the Stonewall (d4) or the Classical System (d3); or g3 is played and we head off on the direction of the Leningrad Variation. But there are also completely independent lines which are hardly playable in the Dutch. For example 1.f4 d5 2.Nf3 Nf6 3.e3 g6 4.d4 Bg7
Instead of, as in humanoid chess, playing the most frequent 5.Bd3 and later c3 to set up a Stonewall, the Bird Opening Powerbook offers in first place the surprising 5.c4!?. A score of 48% does not look particularly tempting, but this performance is above average (for players with White). That need not be a recommendation, but it certainly allows you to obtain the effect of surprise.
