Official Site-PGNs Rd4
Part 1 Games 1-8
GM Hansen made winning look easy in game 10 as GM Vera never got any kind of meaningful threats. GMs Short, Sokolov and Bruzon were very impressive but the prize for the most action-packed game must go to Game 6(Wang-Hambleton) where Wang came withing a micron of winning but did not.

The Highlights
Game 1-Samsonkin,Artiom (2557) - Short,Nigel (2697) 
GM Short got a slight edge in RRN-RRB ending and won nicely with the tricky Spanish Cozio variation.

Game 2-Chirila,I(2519) - Sokolov,I(2642) 
GM Sokolov found a nice way to exploit f2 to win a pawn for a nice victory against the Spanish 6.d3.

Game 3-Hansen,Eric(2587) - Vera,R(2514) 
GM Hansen avoided a big theory duel with 3.Bb5+ and got a nice bind on the dark squares. Black gave a pawn for some attempted counterplay but really got nothing but a lost position.

IM Gerzhoy ground out a nice RRB-RRB ending with opposite color bishops.

Game 6-Wang,R(2484) - Hambleton,A(2580) 
This was a titanic battle between two of Canada's rising talents. IM Wang survived IM Hambleton's attacking tries on the kingside and got a winning queen ending. Just as the win was in sight, Wang made slipped up and allowed Hambleton to get a perpetual.

Game 7-Bruzon Batista,L(2758) - Cao,J(2239) 
GM Bruzon got a nice bind on the whole board and finished the game with a kingside attack.
