I'd suggest focusing on tactics, really. Chess.com's tactics trainer is all right, but I also warmly recommend the tactics trainer on Chesstempo.com. One benefit is that it has a non-blitz mode for tactics, where you're given infinite time to solve your problems. It's great for letting you analyse things thuroughly, especially as a newer player. Chesstempo also has an endgame trainer which is both useful to learn typical endgame themes and also great for calculation - something you can even transfer over to the other stages of the game. Also, tactics in general are perfect to improve consistency, since this is typically where most games are decided on sub-master level.
Otherwise, I'd say a simple understanding of strategy is enough to have, really, so just catching the basics should be enough for a beginner. Something akin to what you find on the Wikipedia entry over "Chess Strategy" should suffice. I don't really think studying master games that much will lead to a lot, as the relevant themes are typically very hard to fully comprehend. If you insist, though, finding annoted games that explain things suitable for your level could be worth considering, and if you're up for some reading, people typically recommend Chernov's Logical Chess - Move by Move for that purpose.
Hi, I'm new to chess study and am looking for foundational information and peer guidance. What I've learned so far is that a student of chess needs to:
And to a degree I'm doing all of these things. But, with so much info out there, I could use help focusing my efforts on what's important and quality (as defined by enlightened minds).
I'm also curious to know if there is any kind of exercise to improve consistency since that seems to be the key to anything where success is determined by one or two mistakes (and my biggest weakness)?
Thanks guys and glad to be part of the group.
