G/40+5 (delay) E11 Bogo-Indian Defense 4...Qe7 Variation (by transposition - 4...Nf6)

1.d4 e6 2.c4 Bb4+

This is known as the Keres-Indian, Franco-Indian and Kangaroo Defense but, since it was first played by Henry Buckle (in 1851), the opening should bear his name.

[3.Nd2 Nf6 4.Ngf3 b6 is a Queen's Indian and =.; For 3.Nc3 see my 2008 KST win over W. Burnett.]

[5.g3 Nc6 6.Bg2 Bxd2+ 7.Nbxd2 d6 is the main line.]

[6.Qxd2 b6 7.Nc3 Bb7 8.Qd3 d6 also looks fine for Black.]

22...h4 23.Nf1

The result of a hallucination. [23...a4 24.Nxc5 dxc5 25.b4 cxb4 26.axb4 a3=/+ , as suggested by my opponent, was best.]

24.fxe4 Bg4+??
This loses. [24...f5 25.Nd2 Qh5+ 26.f3 fxe4 27.Nxe4 Rf8 28.Rf1 b5+/- ]

25.f3 Bh5?
I had intended 25...Qg2+, getting 3Ps for the piece, but that's impossible as the B is in the way and +/= even if the lady could legally leap over him. [>=25...Bd7 ]
