2012–13 Canadian Junior Chess Champions Toronto (2), 26.12.2012
The year's Canadian Junior was a strong 10–player round robin. It was a well organized even by the Chess'n Math Association, which I would gladly play again next year. The event was run at the Britton House Retirement Home, and the venue was quiet and spacious.
In the end, Richard Wang emerged victorious after beating me in a critical game in the 8th round. I was planning on annotating that game, but it already appeared in the CFC newsletter. The game I decided to annotate was my round 2 game against Razvan Preotu. It was an interesting positional battle, which I believe is instructive. 1.e4 c5 2.Nf3 Nc6 3.Bb5 g6 4.Bxc6 dxc6 5.h3

In my opinion, this is the most flexible move, because it prevents Black from having the option of placing the bishop on g4. The next few moves are typical of this sort of position.
