Nakamura Escapes With Draw

14 September 2010, Kuala Lumpur – During the US Chess League, week 4 going into its sixth season, GM Hikaru Nakamura of St Louis Arch Bishops met GM Becerra of Miami Sharks. Internet Chess Club showed the games live on ICC this morning.
Julio Becerra pushed Hikaru Nakamura to the edge on Board 1 of this match, but Nakamura's defense was too stubborn, and it allowed St. Louis (2-2) to hold on to the draw. This was Miami's (0.5-3.5) first score of the season, and will need a strong finish to qualify for the postseason. If GM Renier Gonzalez can continue to play at the level he showed this week, you can't count them out.
The Nimzowitsch- Larsen Opening transpired during the game.

Pix 3. White played 28.Qxe4 taking the bishop. At this point, black missed a stronger move then the one played during the game. Black could have played the stronger 28…Rxe5! keeping the knight at g4 and the possible black check Qe2! as strong counterplay!

GM Becerra of Miami, could have better winning chances had he played 28…Rxe5! earlier in the game but at last the St Louis GM escapes the possible loss and gets a draw for St. Louis Arch Bishops in the 4th round of the US Chess League 2010 shown live on the Internet Chess Club (ICC) this morning.
