It Pours

Unfortunately for Georg Meier the game that he played against Fabiano Caruana in Dortmund was not the only one that he got into time trouble.
A game that I liked (ChessBase 13)

1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 {Kramnik chooses a different approach in the
battle for the full point. He does not want to burn bridges like Caruana did
yesterday but remains true to his positional style.} 4. O-O Nxe4 5. Re1 Nd6 6.

arose which is a clear sign of equllibrum. If the players like then can bring
their heavy pieces along the "e" file and then outside the board, shake hands
and go watch Wimbledon.} g6 14. h3 $5 $146 {[%csl Yf5][%cal Gg2g4] Diagram [#]

light-squared bishop compete for the same good square on f5.} ({The only

for his style.} 15. Bd2 f6 16. Qc2 Bd7 17. b3 Rc8 {Both sides finished
development. The last move is also prophylaxis against the possible c3-c4
advance (White would be very happy to grab space with c3-c4-c5 on the
queenside.) Black also prepares the c6-c5 advance himself.} 18. Re2 ({After}
