The Highlights
Mordiabadi,E-Sambuev,B was the game of the round so far as far as action is concerned but IM Richard Wang got the big result by beating GM Arencibia.

Game 1-Short,N-Hansen,E
GM Short played for a long massage based on better structure and eventually won a pawn. But GM Hansen calmly held the R-R ending for the draw.

Game 2-Sokolov,I-Gerzhoy,L
GM Sokolov built up a nice position and had a vice like grip. However the details of the game are incomplete.

Game 3-Hambleton,A-Bruzon Batista,L
GM Bruzon won a pawn early but could not convert in the RRB-RRB with opposite color bishops ending.

Game 4-Mordiabadi,E-Sambuev,B
This was a real action packed game. GM Sambuev went for the win on the black side of an exchange Slav but took too many risks. The allowed GM Mordiabadi a chance to finish the game with a bloodthirsty attack. 

Game 5-Arencibia,W-Wang,R
GM Arencibia allowed the d-pawn to be cut off and surrounded deep in enemy territory and IM Wang converted without incident in a N-N ending where white labored with marooned Nh6.
