This was previously announced, but some may have missed it.
Graz 2003 produced two chess positions that the reknowned editors of Chess
Informant have deemed worthy for inclusion in their esteemed Combination section
of Chess Informant #89. To the best of my recollection ,this is the first time
positions arising from computer vs computer games have been selected for this
honor and to have two positions selected in one volume is even more amazing.
Congrats to all programmers involved.
You will find these positons on page 341. The annotations below are copyrighted
by Chess Informant are best read by CI Expert 5.0 and other fully compliant PGN
reader that can read the PGN-NAGS (funny looking text with $ symbols).
