In first round tiebreaks, it looks like Kamsky passes through to round 2 while Ramirez went the full tiebreak but lost in the final game. So 4 of the 9 advance to the round of 64.
American results from round 2, game 1…
Nakamura leads Safarli, 1-0
Kamsky leads Shimanov, 1-0
Dominguez leads Onischuk, 1-0
Ivanchuk leads Robson, 1-0
IMO, nothing massively surprising in these results. Robson will have to win as black in game 2 to force tiebreaks. Onischuk has to win as well, but at least will have white. However, Dominguez has been playing VERY well recently, so that’s no picnic. Nakamura and Kamsky both have black, but effectively have draw odds, which is nice for them.
Game 2 is in progress now…unfortunately, I have to work. Booooooo. 
American cumulative results from round 2, game 2…
Nakamura defeats Safarli, 1.5-0.5
Kamsky leads Shimanov, 1-0**
Dominguez defeats Onischuk, 1.5-0.5
Ivanchuk defeats Robson, 2-0
** - As I write this, Kamsky is still playing in the second time control, but unless Shimanov loses his mind, that match is going to tiebreaks. I give Shimanov credit for uncorking a King’s Gambit in a must-win situation. Kamsky spent most of the first time control in horrible time pressure, almost certainly as a result of the opening. A wild, wild game…but it appears Shimanov has emerged from the time scramble with a winning advantage.
Safarli pressed Nakamura for a while, but the US #1 never looked troubled, and rolls through to round 3.
Onischuk drew in 21 moves. The Summer of Dominguez continues.
Robson, to his credit, played to win. But it looks like “good Chukky” showed up in Tromso…at least, so far.
Game over - Gata goes to tiebreaks
Kamsky defeats Shimanov 2-0 in tiebreaks, and advances to the third round.
Other interesting (well, to me anyway) notes from Tromso…
Norway has a player still alive in the World Cup - Jon Ludvig Hammer. He upset David Navara 2-0 in tiebreaks to advance. This is of interest to American fans, because he plays Kamsky next.
Wei Yi, the world’s youngest GM, has dispatched Ian Nepomniachtchi and Alexei Shirov in consecutive rounds - without tiebreaks. Wang Yue has said that Wei is already playing at 2700 strength. It’s hard to argue with GM Wang’s evaluation after this start. Next up, though, is Mamedyarov, who certainly won’t be caught off guard.
Julio Granda Zuniga is through to round 3. Next up for the veteran: Anish Giri.
If it’s possible for a 2770 player to be under the radar, Boris Gelfand has been that player. He plays Alexander Moiseenko next.
Ever heard of Yuriy Kryvoruchko? Michael Adams has now, after the Ukrainian GM sent him packing in tiebreaks. At least one Ukraine player is guaranteed of reaching the fourth round, as Kryvoruchko next plays Vassily Ivanchuk.
Hikaru Nakamura is paired against India’s Baskaran Adhiban in round 3.
Can any strong player explain why Onischuk gave a draw with White in 21 moves, in an equal position, when faced with elimination?
I played and drew Adhiban (Nakamura’s next opponent) in the 2007 Aeroflot Open. I was Black in the Sicilian Najdorf, where he played 6. f4. I doubt it would be of any use for Hikaru’s prep though, since it was in the “B” section of that event (3rd highest section out of 4 sections total).
Yura Kryvoruchko is a young out-and-out chess professional, who is well known in Europe, where he plays in many national chess leagues and travels from tournament to another open tournament. He is a very nice guy too. Yuri Shulman introduced me to him in Reykjavik.
By my count, out of 32 players remaining in the draw, 11 are from Russia, 6 are from Ukraine, USA and Azerbaijan have 2 each, and 11 other countries 1 each.
Michael Langer
Later Edit: Kryvoruchko was the winner of 2013 Ukrainian Championship, where all the country’s top players participated, except Ivanchuk.
Nakamura and Kamsky both win their opening games in round 3. Caruana draws, Aronian loses, Kramnik draws, Ivanchuk draws, Gelfand won.
And onto Round 4 for both Nakamura and Kamsky! Kamsky drew and Nakamura
scored another win. Caruana still playing.

Both Americans get a day off while the tiebreaks for round 3 go on.
Tomashevsky, who eliminated Conrad Holt in Round 1, has now also eliminated top seed Aronian.
6 players are through to the next round and 2 of them are Americans: Nakamura and Kamsky. The others are: Tomashevsky and Svidler (both from Russia), Gelfand (Israel), and Vachier-Lagrave (France).
Round 3 is in the books.
Pairings for the “sweet sixteen” (American player in bold):
Tomashevsky - Morozevich
Kamsky - Mamedyarov
Le - Svidler
Karjakin - Andreikin
Caruana - Granda Zuniga
Gelfand - Vachier-Lagrave
Kramnik - Ivanchuk
Nakamura - Korobov
Patzeriffic comments on round 3 (shhh - don’t tell my employer)…
There is certainly a heavy aspect of luck in this format, but man, is it fun to watch. 
Only three of the remaining players have advanced to this stage without needing tiebreaks. Two of them, Gelfand and MVL, play in round 4. The third? Nakamura.
Only one player remains in this event rated under 2700 - Julio Granda. He’ll play Caruana, who by his own admission was lucky that Malakhov didn’t win their first tiebreak game.
Tomashevsky is doing quite nicely at this event. It’s good to see him rebound from what had to be a most disappointing Olympiad.
The money differences start becoming pretty noticeable around here. Losers in round 4 clear $20,000. Losers in round 5 (quarter-finals) clear $28,000. Losers in round 6 (semi-finals) clear $40,000. The runner-up clears $64,000, and the winner clears $96,000.
Finally, if you haven’t had a chance to check out the live feed and commentary, it’s not bad at all. Lawrence Trent and Susan Polgar are a good commentary team. Polgar is especially good at pointing out ideas and moves to increase amateur understanding.
Did I look at the pairing charts correctly - if Nakamura and Kamsky win their upcoming matches, they will be paired with each other? Or did I read wrong?
Boyd reported the R4 pairings as they are placed in the draw, so:
If Kamsky goes through, he will play the winner of Tomashevsky - Morozevich.
If Nakamura goes through, he will play the winner of Kramnik - Ivanchuk
They won’t face each other before the final match.
Added country and FIDE rating for grins
Edit to correct listing for Granda Zuniga
The players are paired through their bracket - sort of like the NCAA basketball tournament - not through resetting the order based on ratings
Take a look. Good day for Gata.

Round 4, game 1 is done. Match scores after today’s games:
Tomashevsky 0.5 - 0.5 Morozevich
Kamsky 1 - 0 Mamedyarov
Le 0.5 - 0.5 Svidler
Karjakin 0.5 - 0.5 Andreikin
Caruana 1 - 0 Granda Zuniga
Gelfand 0.5 - 0.5 Vachier-Lagrave
Kramnik 1 - 0 Ivanchuk
Nakamura 0.5 - 0.5 Korobov
The notation to Kamsky’s win against Mamedyarov is provided upthread. Having watched the broadcast of it, I’ve basically decided to give up competitive chess forever, because I’ll never be able to play like that.
Kramnik ground away with an outside passer in a level Q+R ending, and was rewarded when Ivanchuk erred just after time control. Kramnik gets the luxury of only needing a draw with White tomorrow to advance to the quarterfinals.
Caruana didn’t seem to get a lot out of the opening, but Granda simply blundered on move 20, and resigned after Caruana’s 21st.
Round 4 1st game
5 draws
Kamsky, Caruana, and Kramnik win take a 1-0 lead in their matches.
Gata recovers from a very difficult position and forces a draw in his match. Coupled with his win yesterday Gata goes through to the round of 8.
