Hi Steve,
I used Junior 9 to do a "Blundercheck" analysis of this game. It appears to be
pretty well played, the RES-Deep Sjeng did miss one chance to win big - here's
the analysis from Junior 9 [followed by the Blundercheck output]:
[D] r3r3/pppN1kpp/5p2/8/4b3/1P2P3/1PPR1KPP/R7 b - - 0 1
713: Saitek Sparc 1MB - Resurrection Deep Sjeng 1.8, Blitz:60'
r3r3/pppN1kpp/5p2/8/4b3/1P2P3/1PPR1KPP/R7 b - - 0 1

For the Blundercheck, I had Junior 9 set to search each move for 30 seconds with
a threshold of 0.50, meaning if it thought one side lost a half a pawn on one
move, it would suggest an alternative. Here's the Blundercheck output, which you
should be able to post into any Chessbase program to view well:
[Event "Blitz:60'"]
[Site "?"]
[Date "2005.10.16"]
[Round "?"]
[White "Saitek Sparc 1MB"]
[Black "Resurrection Deep Sjeng 1.8"]
[Result "1/2-1/2"]
[ECO "C50"]
[Annotator "Junior 9"]
[PlyCount "80"]

Hope this is educational and entertaining. Note Junior 9 agrees with you that
the Ra5-a2 maneuver is not best, after a minute on my computer Junior 9 chooses
Ke7.
3 Cheers for the Resurrection Regards,
