The Bird's Opening
The Bird's Opening (or the Dutch Attack), which is a standard flank opening, is a chess opening characterized by the move:
1. f4
White's strategic ideas involve control of the e5-square, offering good attacking chances at the expense of slightly weakening his own kingside. Black may challenge White's plan to control e5 immediately by playing From's Gambit (1...e5); however, the From Gambit is notoriously double-edged and should only be played after significant study.
The Encyclopaedia of Chess Openings assigns two codes for Bird's Opening: A02 (1.f4) and A03 (1.f4 d5).
The opening was mentioned by Luis Ramírez de Lucena in his book Repetición de Amores y Arte de Ajedrez con Cien Juegos de Partido, published c. 1497. In the mid-nineteenth century the opening was sometimes played by La Bourdonnais and Elijah Williams, among others. The British master Henry Edward Bird first played it in 1855 and continued to do so for the next 40 years. In 1885, the Hereford Times named it after him. In the first half of the 20th century Aron Nimzowitsch and Savielly Tartakower sometimes played 1.f4. In more recent decades, grandmasters who have used the Bird's with any regularity include Bent Larsen, Andrew Soltis, Lars Karlsson, Mikhail Gurevich, and Henrik Danielsen.
Black's most common response is 1...d5, when the game can take on the character of a Dutch Defense (1.d4 f5) with colors reversed. White will then often either fianchetto his king's bishop with Nf3, g3, Bg2, and 0-0 with a reversed Leningrad Dutch; adopt a Stonewall formation with pawns on d4, e3, and f4 and attempt a kingside attack; or fianchetto his queen's bishop to increase his hold on the e5-square. Another strategy, by analogy with the Ilyin–Zhenevsky variation of the Dutch Defense, involves White playing Nf3, e3, Be2, 0-0, d3 and attempting to achieve the break e3–e4 by various means, e.g. Ne5, Bf3, Qe2 and finally e3–e4, or simply Nc3 followed by e4. Timothy Taylor's book on Bird's Opening suggests as a main line: 1.f4 d5 2.Nf3 g6 3.e3 Bg7 4.Be2 Nf6 5.0-0 0-0 6.d3 c5.
White can also play 2.c4, the Mujannah-Sturm gambit. This is a decent opening and seems to borrow ideas from the Réti Opening (1.Nf3 d5 2.c4) and the Queen's Gambit Accepted. Eventually, this move order is followed by Nf3. The best move in this position is 2...d4, where the game continues in the style of the Réti Opening, with 3.Nf3 being a possible next move. 2.c4 is not a true gambit, since if Black tries to hold on to his pawn, he will be punished (2.c4 dxc4 3.e3 b5? [Black should pursue development instead] 4.a4 c6? 5.axb5 cxb5 6.Qf3, where Black must part with a minor piece, akin to the Queen's Gambit Accepted trap).

Black's sharpest reply is 1...e5!?, From's Gambit, named for the Danish chess player Martin Severin From (1828–1895). White then has the option to transpose into the King's Gambit with 2.e4. This is an important option which may cause Black to consider playing a different line if he wishes to avoid the King's Gambit. It has been observed that one of the possible disadvantages of From's Gambit is that it is very easy for White to avoid.
If White accepts the gambit with 2.fxe5, Black must choose between the main line 2...d6 and the rather obscure 2...Nc6. After 2...Nc6, International Master (IM) Timothy Taylor, in his 2005 book on the Bird's, recommends 3.Nc3! Nxe5 4.d4 intending 5.e4, rather than 3.Nf3?! g5! when Black stands well. After the normal 2...d6 3.exd6 Bxd6, White must play 4.Nf3, avoiding 4.Nc3?? Qh4+ 5.g3 Qxg3+ 6.hxg3 Bxg3 checkmate. Then Black again has two alternatives: 4...g5 to drive away White's knight, and 4...Nf6, threatening 5...Ng4 and 6...Nxh2! Future world champion Emanuel Lasker introduced 4...g5 in the game Bird–Lasker, Newcastle upon Tyne, 1892, so it is known as "Lasker's Variation". Taylor considers 4...g5 dubious; a quiet response that he considers favorable for White is 5.d4 g4 6.Ne5! (6.Ng5? leads to a dubious piece sacrifice) Bxe5 7.dxe5 Qxd1+ 8.Kxd1 Nc6 9.Nc3! Be6 (9...Nxe5?! 10.Bf4 f6 11.Nd5 Kd8 12.Nxf6!) 10.Bf4 0-0-0+ 11.Ke1 Nge7 12.e3 Ng6 13.Bg5 Rdf8 14.Bf6 Rhg8 15.Be2 Ngxe5 16.Rf1 "with the typical edge for White that is characteristic of this variation", according to Taylor. He also considers the sharper 5.g3 g4 6.Nh4 favorable for White, giving as the main line 6...Ne7 7.d4 Ng6 8.Nxg6 hxg6 9.Qd3 Nc6 (9...Rh5 10.Bg2; 9...Na6 10.c3) 10.c3 (10.Nc3? Nxd4! 11.Qxd4?? Bxg3+ wins White's queen) Bf5 (10...Qe7 11.Bg2! Bd7 12.Nd2 0-0-0 13.Ne4! favored White in Taylor–Becerra Rivero, Minneapolis 2005) 11.e4 Qe7 12.Bg2 0-0-0 13.Be3. According to Taylor, White has a large advantage in all lines, although play remains extremely sharp, e.g. 13...Rde8 14.Nd2; 13...Rxh2 14.Rxh2 Bxg3+ 15.Kd1 Bxh2 16.exf5! Re8 17.fxg6! Qxe3 18.Qxe3 Rxe3 19.gxf7; or 13...Bd7 (threatening 14...Rxh2!) 14.Bf2!
