You could try setting up a home computer to run analysis on your practice games. A modern desktop PC has more than adequate processing power for the task. A decent laptop can probably handle it as well, if you have one of those instead. I always play a much stronger game after seeing where I'm going wrong with that.
Chessbase products have a really good user interface and are great for running full game analysis. (If you go to buy chessbase software, make sure you get the USA site. If you buy in euros, the exchange rate will kill you!) A few choices on engines to pick from. When it comes to just analyzing a specific position, I tend to prefer Arena 3.0 for the task.
Also, give the Tactics Trainer on this site a try if you haven't already. That's about the extent of my own wisdom on the matter. I'm still learning the ropes, myself.
Hello, I am a kid with a USCF rating of 1341 (WA scholastic of 1419), and I was wondering what would be the most effective training method. If anyone knows of any books/software/study methods that you think would help, please tell me!
