I would like to know where does the analysis takes place. Does it run run on the server or client (pc/tablet or mobile).
The new analysis runs on chess.com's servers.
From the announcement to the Beta group:
Finally, a note on the strength of the analysis this feature offers, because this is a huge difference between the new Analysis and the old. (Thanks for raising this in the Comments, @fayfay1 !) The "full" analysis that runs on your game to create the Report, analysis data, and Retry Mistake positions is extremely fast. It is better than the "Deep" analysis you used to wait for, because instead of leaning on client-side/browser-based tech, the new analysis is done by a large cluster of server-side engines. In ~5 seconds, every move is analyzed to a depth of 20 or more, and we are adding even more muscle there soon. In summary, there is only one level of analysis quality available now, and it's the best we have ever provided! (And you won't have time to make a snack while you're waiting for it.)
