8/25/2015 – It started relatively dull, but boy did today's round pick up quickly! Two draws between MVL vs. Aronian and Giri vs. So were rather boring, but it was more than offset by the other three games! Grischuk beat Anand in tough struggle, while the Caruana and Carlsen game went literally down to the last seconds. Finally, in a long and beautiful positional game, Topalov became the new leader.

Daniel King shows the highlights of round 2
Today’s round did not start with the fireworks and spectacular sacrifices of yesterday, but it ended up having an incredible amount of excitement.
MVL was unable to put pressure on Aronian
The first game that finished today was a relatively dull draw between Maxime Vachier-Lagrave and Levon Aronian. The Frenchman tried to repeat a Ragozin that Topalov used against the Armenian player in Norway, but Levon was not one to be surprised. He came into round two with a good improvement by solidifying his position and making it very difficult for MVL to make any real threats. The resulting endgame was equal; White’s control of the a-file didn’t give him any advantage as Black was sufficiently active with his king. The game ended in a draw soon afterwards after only an hour and a half of play.

The next game to finish was also a draw: a very blocked position arose from the English opening in Anish Giri vs. Wesley So. Perhaps the Dutch player had a very small advantage from the opening with the superior pawn structure, but it wasn’t much. Eventually So was able to position his pieces well and advance the queenside pawns, while Giri did not create any real threats. The game was drawn in an opposite colored bishop endgame.

Anand starts with 0.0/2, but he isn't the only one
Grischuk mentioned this is his first win against a top-10 player this year, but more importantly:
in 15 years of encounters, this was his first win ever in classical time controls against the Indian.
The first decisive game of the day was the match between Alexander Grischuk and Vishy Anand. The Russian played the “correct bishop opening”, as he calls it, and obtained a slight edge after Anand’s inaccurate and somewhat strange development. Grischuk was in severe time trouble, but with the positional pressure. Anand tried to complicate the game, but he ended up making mistakes while playing quickly. Grischuk punished the mistakes accurately and won the game.

1.d412Nf662.Bf4!?12 Some kind of London system, completing bypassing theory. This is usually done after Nf3, but Grischuk skips this move for quite a while.

The clock was extremely important today in this match
Fabiano Caruana against Magnus Carlsen was a heartstopper. In a position that was very interesting, both players simply let their clock run out way too low. An unbelievable time scramble occurred, with both players falling to mere seconds to make their final moves. The engine evaluations kept changing wildly as the game became a bullet battle. On move 40, Caruana made a horrific blunder with only seconds left on his clock. He resigned as soon as he made time control.

Finally, Veselin Topalov became the sole leader of the 2015 Sinquefield Cup. He played an excellent pawn sacrifice against Hikaru Nakamura, taking a commanding control of the dark squares in return for the lost material. Nakamura could not hold his position together and was forced to return his material, but his position was not good: Topalov’s bishops were dominant. After much maneuvering, Topalov reached a winning endgame thanks to a cute zugzwang and converted his win.
The leader of Sinquefield 2015 and the Grand Chess tour: Veselin Topalov
