The Bird’s Opening (1.f4) is a fan favorite and frequently visited by speed chess players. Some may call it crazy or even solid at times because of its ease of application to the Stonewall Structure. The Bird’s Opening resembles the Dutch variation (1.f5) from Black and is so regarded as the Reverse Dutch. The Bird’s Opening is commonly ignored in mainstream opening theory, although it provides White with a creative and unconventional way forward. By immediately challenging possession of the e5 square, it facilitates dynamic, asymmetrical play. The Bird’s Opening, named after 19th-century English master Henry Bird, appeals to players who want to engage in rich strategic engagements outside of standard e4 or d4.
Players who use 1.f4 these days typically use the Polar Bear system with the f4, g3, d3, Nf3, Bg2 structure, which is played by Nihal Sarin, the rising Indian star; Magnus Carlsen, the current world number one; and Ian Nepomniachtchi, who has won the Candidates twice among many other players. However, it is not the only method to play this line; another structure, the Stonewall, with d4, e3, f4, provides a more sturdy play.

Apart from speed chess, Nodirbek Abdusattorov played 1.f4 in the Saint Louis rapid in 2024 against Fabiano Caruana, making a bold choice. He had opted for a pretty stable structure, and this was his position in 6 moves.
