As I was awake early this morning before the alarm was set to sound, I grabbed my iPad from the side of the bed and tried the Black side against HIARCS.
HIARCS -- James Stripes [C50]
Spokane, 07.04.2015
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.0–0 d6 5.d3 Nf6 6.Bg5 h6 7.Bh4 g5 8.Bg3 h5
These moves were played in Dubois -- Steinitz, London 1862, and several times since.
9.Nxg5 leads to the starting position for my play against the iPad. Dubois played 9.h4.
Black to move
9...h4 10.Nxf7 hxg3 11.Nxd8 Bg4 12.Qe1 Nd4 13.h3 Ne2+
All these moves have been played several times in a fourteen move miniature.
White to move
14.Qxe2N
It is strange that this forced move does not appear in the database.
14...Bxe2 15.Ne6 Bxf1 16.Kxf1
Black to move
16...Bxf2? 17.Nxc7+ Ke7 18.Nxa8 Rxa8 19.Nd2 Rh8 20.Rd1 1–0
Black is down two pawns with no compensation.
I tried again, seeking improvements in my play.
HIARCS -- James Stripes [C50]
Spokane, 07.04.2015
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.0–0 d6 5.d3 Nf6 6.Bg5 h6 7.Bh4 g5 8.Bg3 h5 9.Nxg5
Starting position
9...h4 10.Nxf7 hxg3 11.Nxd8 Bg4 12.Qe1 Nd4 13.h3 Ne2+ 14.Qxe2 Bxe2 15.Ne6
As before. This position is in the diagram above.
15...Bb6 16.Nc3 Bxf1 17.Kxf1 gxf2 18.Na4 Kd7 19.Nxb6+ axb6 20.Kxf2
Black to move
20...c6
20...b5 This attempt at a decoy is better. Black must expand on the queenside in order to create a position where his rooks have mobility.
21.Bb3 c5 22.Ng5 with a slight edge for Black.
21.Ng5 d5?
A positional error. 21...b5 is far more sensible.
22.exd5 cxd5 23.Bb5+ Ke7 24.Re1
Black to move
24...e4?
24...Rhf8
25.dxe4 Nxe4+ 26.Nxe4 dxe4 27.Rxe4++- 1-0
I played a few moves more, but it is clear that White has a decisive advantage. Playing a lost position against a computer is a waste of time.
I am becoming unconvinced that 9.Nxg5 is an error. But, the miniatures stem from lines where Black sacrifices his or her queen. Afyer 9.Nxg5 h4 10.Nxf7, Black could play 10...Qe7.
