Kasparov had a slight advantage in a queen and pawn vs. queen and pawn endgame. However, for some reason the e-mail containing the analysis by Krush did not arrive and was not posted on time. Therefore, the majority picked another move, not the move recommended by Krush.

I recommend the World plays the move 58...Qf5 (Queen on f3 to f5)
I believe that the active move 58...Qf5 is Black's best way to continue fighting for a draw (Analysis has revealed severe problems with the alternative 58...Qe4 - and it looks bad for Black. I think 58...Qe4 is probably losing by force according to the latest analysis on the World Team Strategy Bulletin Board). Therefore 58...Qf5 to give us our best chances.
When the analysis by Krush arrived and was posted, it showed that the move actually played by the Rest of the World lost by force.
Krush then declared the position to be hopelessly lost, delivered her final analysis, her kudos and her thanks to all and dropped out of the team, a great blow since the majority had been following her recommendations up until that time.
Frustrated, voters for 58. .... Qf5 decided to vote for 59 .... Qe1, which was a Queen sacrifice mentioned in the last line of the analysis by Krush and which would have lead to an instant loss for Black, the equivalent of resigning.
When the vote results came out, MSN rejected all votes for 59 .... Qe1, which was a perfectly legal and legitimate move, even though it would have given away a queen for nothing .

KRUSH MOVE 59 COMMENTARY
SUMMARY
I wish to thank the World Champion, MSN, and First USA for their gracious invitation and for extending me the privilege of participating in this event. I wish to thank my fellow analysts on the World Team Strategy Bulletin Board, GM Chess School and SmartChess Online for the privilege of being able to work with them.
I do not have a specific recommendation for this move. However, in my Analysis section, I present the World Team's distilled knowledge about the position after 58...Qe4, and Kasparov's response 59.Qg1+. This analysis is a testament to the resolve, dedication and fighting spirit displayed by brilliant and enthusiastic analysts all over the world, whose imagination was captured by this intriguing event. I believe this analysis will guide you more effectively than my personal recommendation on this move (all of Black's options are indicated).
ANALYSIS
As I indicated in my previous post, which can be found in the Game History file, I believe the move 58...Qe4 is a losing move - in my opinion 58…Qf5 was necessary to continue the game. After 59.Qg1+, we can do a limited but exhaustive search of all of Black's options, as our King will reach one of eight squares (a1 through d1, or a3 through d3) after White follows up with 60.Qf2+.
As we shall see, a common theme in these variations, is White's ability to play a quick Kg7-f6, followed by g6-g7. This maneuver would not have been possible after 58…Qf5 (maintaining watch along the f-file and in particular the f6-square). Black is unable to maintain perpetual check in these variations, and therefore White wins as the pawn on g7 (about to queen) is much more powerful than Black's slower d-pawn.

A1) 60...Kd1 61.Kf6 d4 62.g7 Qc6+ 63.Kg5 Qd5+ (63...Qc5+ 64.Qf5 Qe7+ 65.Kg6, White wins) 64.Qf5, with:

C6) 60...Kc3 61.Kf6 d4 62.g7 Qc6+ 63.Kg5, and now:
C6a) 63...Qd5+ 64.Qf5 Qg2+ (64...Qd8+ transposes to 63...Qe8 64.Qf5 Qd8+ - Variation C6b - White wins) 65.Qg4 Qd5+ 66.Kf4 Qg8 (66...Qf7+ 67.Kg3 Qg8 68.Qf3+ d3 69.Qf8, White wins) 67.Qg6, White wins.

C6b2) 65...Qd6+ 66.Kh5 Qh2+ 67.Kg5 Qg3+ 68.Kh6, White wins.
Finally, we should not forget:
D) 59…Qe1, when after 60.Qxe1+, White wins as Black's Queen has left the game.
After 59.Qg1+, I am unable to find any defense for Black.

However, the 7 million who according to Microsoft were following this game would have learned a lot about chess by seeing this played out. Comments on the bulletin boards showed a general lack of understanding of this position.
The analysis by Krush (above) gave: 62.g7 Qc6+ 63.Kg5 Qd5+ (63...Qe8 64.Qxd4, White wins) 64.Qf5 Qg2+ 65.Kh6, White wins.
Kasparov has stated that even had the Rest of the World played the move Krush recommended, which was 58. ... Qf5, he still would have won, and he will supply analysis proving this at some future date, but not just yet.
