I've been wanting to practice with a program like this for a while, so thanks for making it avaiable.
I also have an idea for a new set pf features, but if this was going to be the last version of the program then I might just write a seperate program for that as it would involve quite an extensive rewrite.
I uploaded the latest (and perhaps last) version of my program "GuessTheMove" to the chess.com download section. Previous versions have had a total of 6500 downloads. Please give my program a try; it is free forever and runs under Windows. I wish to thank the many people who have used it and given me valuable feedback. Bug reports and further suggestions are always welcome. Here is a link.
