Analyzing Games Best Software
I have found that the fastest way to improve in chess is to analyze the games you have played, especially those you lost, and find your errors. Then hopefully in the future you will not make the same mistakes. I have been testing free software to find out which is best for doing this. So far I have found Lucas Chess to be the best one. You can download it freely and it has many neat features. To analyze games we click tools--pgn viewer--paste pgn and then we click utilities--analyze. If you have any problems with this software you can contact Lucas himself and unlike other developers of free software he is happy to help you out!
