Tactics trainer analysis

Hi,

Sorry to be so thick , but how is one meant to use the tactics trainer "source and analysis" information

Obviously I can read it and play it out on a (physical) board, but is there a way withing chess.com to play through the different variations? Should I be using some other software?

Thanks.

If you don't want to play it out on a physical board, click on "Open Analysis Board" which is next to "View Analysis & Source". You can have both the board and the analysis open at the same time. With a little adjusting of window size, you can fairly conveniently go back & forth between the two. One thing I especially like about the Analysis Board is that when it opens the pieces are already arranged as they are at the beginning of the problem.
