Black needed to play Rf8 here inorder to have any chance of holding the draw.

It's already too late. Black is lost here, and neither Rf8, nor Rg8, nor Qf3 can save the day (among other possibilities).

what a pity the coverage of this event is awful. all i know is, that SF won 3:1

[Tord Romstad]

Wow, very interesting match. Thanks for making this happen, Jesse! Thanks also to everybody else who made this possible, not least Hikaru Nakamura himself, who must have had a tremendously exhausting day. I think he would have done better at a more relaxed rate of one game per day.

I don't follow computer chess news as closely as usual right now, and almost missed this match entirely. I wasn't even aware of this event until midway through the second game, and unfortunately I had to go to sleep by the end of the third game. This morning, I was surprised to wake up and discover that the entire world seemed to have grown tired of the match by the halfway point, and that there was hardly any information to be found about the last two games. Even now, eight hours or so after the end of the final game, the final result of the match is quite hard to find on the Internet, including this message board. For those who still don't know, it appears that SF won by 3-1, winning the second and fourth games. I still haven't been able to find the moves of the last two games.

I think Nakamura played for over 10 hours yesterday, against an opponent that doesn't make any obvious errors. Must have been torture for Nakamura. Here are the results:
Game 1: Draw
Game 2: Stockfish won
Game 3: Draw
Game 4: Stockfish won
final score Stockfish 3 - Nakamura 1
Here's a stream of a portion of the second game, and the final two games commentated live by a NM I think. http://www.twitch.tv/zugaddict/b/561225791
