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.

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)

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.
