Staunton was the first to play the Bird opening.
1...d5 2.Nf3 c5 3.e3 Nc6 4.Bb5!
playing the Nimzo-Indian with White,with an extra tempo.
a loss of time,because White has already the intent to change in c6.
5.Bxc6+ bxc6 6.0-0 e6 7.c4!
blocking the doubled pawn,today it is a standard manoeuvre that Nimzowitsch explained in the '20 years.
7...Nf6 with the idea Nd7 to defend the c5 pawn was better.
8.Qe2 Bd6 10.Nc3 Qe7 10.b3
to put the Bishop in a3 and the Knight in a4,another standard manoeuvre in the Nimzo-Indian
10...f6 11.d3 0-0 12.e4 dxe4?
now the weakness of Black's pawns is more and more emphasized.12...d4 was also bad for 13.Na4 and 14.Ba3.better was 12...Bb7!
13.dxe4 e5 14.f5 Nf7 15.Nh4 Bd7 16.Rf3 Rfd8 17.Be3
White now doesn't need to develop the Bishop in a3,in fact in e3 it is better positioned.
17...Be8 18.Raf1 Ng5 19.Rg3 h6 20.Qg4!
putting pressure on the Kingside.
20...Rd7 21.Nf3! Kf8
21...Nxf3+ 22.Rhxf3 Kh7 23.Bxh6! Kxh6 24.Rh3+ is winning for White
22.Nxg5 hxg5 23.h4 Bf7
the decisive mistake,but also after 23...gxh4 24.Qxh4 Kg8 25.Rh3 Qf8 26.Na4 Rad8 27.Qf2 Black's Queenside collapses.the rest is easy for White.
