|May-31-07|| ||chessamateur: Good to see the Levy-Chess 4.7 match games are up. Levy had a scare here in the first game and was lucky to escape with the draw. 12... Nxe3! was a big surprise.|

8.a3? is a wasted move (8...e4 gives black the advantage). White should try 8.e3 8.c4 or 8.Nxe5 Nxe5 9.d4 with equality.
11.e3? is not best - perhaps 11.c4 is better.
The machine missed 14...f5! winning fast in all lines.
55...Nxe7? is a big mistake that gives white the game with best play (55...h3+ is likely best here, leading to a draw).
White missed 57.Bc3! followed by Be5 and the promotion of the b-pawn, in a winning line.
After 57...Kf6! the game is drawn, as played.

Perhaps I am missing something, but doesn't black still draw with 57...Re8 or Rg8 followed by Kf7. A line involving Ba5 (intending Bd8) looks more dangerous.
|Oct-24-07|| ||Petrosianic: Levy explained in <Chess Life> that he had played such an offbeat opening setup, so as to avoid the computer's book. The game he lost is the only one where he flat out tried to out-tactic the computer.|

|Oct-24-07|| ||RandomVisitor: Chess 4.7 was apparently out of its opening book after 5.0-0.|
Of Levy's choice of opening moves, he has this to say from the November 1978 Chess Life and Review:
"Before you all rush out to 'Ask the Masters' [a section of Chess Life and Review where readers pose questions to a panel of Masters] complaining about my opening play, permit me to point out that when faced with a strong computer program I try to play the opponent, not the position. It was my plan to create a situation where nothing was happening and then to expand gradually on the Queenside. Unfortunately, the program had read my article in the June 1977 CL&R and found out how to attack on the Kingside."
