Hello Bruce,
Maybe not such a good example as I don't know if it is free to use, for your own
purposes surely, Michael Gurevich used this game for his testposition Nr 58 in
CSS forum. http://f23.parsimony.net/forum50826/messages/132916.htm
It has lots of comments by Peter Wells, in Shredder's interface it parses
alright I believe.

1. Nf3 c5 2. c4 Nc6 3. Nc3 g6 {I fancied before the match that I knew John
Emms' repertoire pretty well, but at the same time respected its flexibility.
This was about third on the 'expected' list, and received a level of
preparation commensurate with that. I notice that Malcolm Pein on 'Twic TV'
recalled that his early chess education had led him to believe that this move
was something of an innacuracy. Well, I can't believe that I am really
anything like as old as Malcolm, but I have to say that the same set of ideas
were knocking around in my youth too. The supposed reason was two-fold: 1)
The game continuation was not trusted for black. 2) After my next move ...} 4.

problematic ( NCO for example is rather dismissive of black's line on this
ground ). However, I had spotted John's game with Steve Giddens ( see below )

in the Emms opening collection without due consideration.} Ne4 8. cxd5 Nxc3 9.

are clear - they lie on the dark squares, and a potential weakness of the c6
pawn. However, his position has plus points too: 1) He has a major potential
asset in the bishop pair, and with it chances for a superiority on the light
squares. 2) Although c6 can be weak, white must also in due course be wary of
black implementing the ...c5 break when the assets mentioned above really
come into their own. 3) In the absence of white's light-squared bishop black
can consider moves such as ...f6 to reclaim some dark square control, without
any serious danger.} 13. Bf4 $1 {This was about as far as my preparation went.
I had to check two things: 1) That if black exchanges on b3 then his queen is
sorely missed from the defence of c6 while he opens the a-file and further
increases the disparity between the development of the two sides. 2) That in
my view if white, fearing the exchange of queens spends a tempo running away,
then black has no problems. A couple of examples:} (13. Qc3 Bg7 (13... f6 14.

As I saw it, white must keep the initiative, and on the negative side, to do
this, ...c5 has to be prevented at pretty well any costs. Having said this, I
had of course seen the coming further sacrificial idea, although not yet
worked out the details. Basically on the positive side, this is an exchange of
a pawn for two tempi, and given white's forces in the vicinity of black's king,
and even more important the difficulty black's forces experience in scrambling
back to the defence, it seems intuitively well justified.} (19. b3 $6 c5 $132)

it is also important that black's only other working defensive piece, the
queen, is forced off the 4th rank.} Bxc5 23. Rxc5 Qd6 {I expected this at the

Again Fritz finds a quicker win with the immediate transfer of the rook via e5
or c3. However, as Malcolm Pein says, this is the most plausible human move -
black is hopelessly tied up and white can still bring the rook round at
leisure. In any case, having sacrificed a piece, it is aesthetically very
satisfying if the extra piece is actually harmful to the opponent. Here it
prevents moves like ...Rd7 which could at least question white's attacking
forces.} Rxf8 31. Qxf8 Be8 (31... Qxc5 32. dxc5 Rg7 {
