Learning from GM-Annotated games from the 2009 Canadian Open Chess Championship
The 2009 Canadian Open Chess Championship is currently happening over in Edmonton, Alberta, Canada from July 11th-19th 2009. Top players participating include GM Alexey Shirov, GM Ni Hua, GM Michael Adams, GM Surya Ganguly, GM Victor Mikhalevski, and local GM Mark Bluvshtein. Being a Swiss, the first round saw the usual mis-pairings but which can be beneficial for us woodpushers at club level. As previously noted, it is instructive to see how a lower rated player match wits with a higher rated player. In addition, some the Rd 1 games were annotated by US (formerly Latvian) GM Alexander Shabalov (well-known for the Shabalov Gambit within the Botvinnik Semi-Slav system). I post his annotations together with the game in replayable format. I trust Club members can learn and benefit.
One of the best way to improve is to follow the Kotov Training method: Play through a game to the finish and try to identify the critical moments in the game. Then backtrack to the critical moments and analyse it for a set time period (say 10-2omin max). Compare your analysis with GM analysis. Note that this is Kotov's real contribution to chess improvement. His more well-known "candidate-move" theory has been disputed in recent years and has been subject to many imporvements and modifications. But this Kotov Training method has never been "refuted". Also note that in some games below the GM may not have noted those critical moments.
