In addition to that, how is it possible to check some players ratings related to their variants?
I suppose there are a bunch of shortcomings, and I hope these problems will be solved.
Atomic chess

I've emailed the moderators a bunch of times, but they seemed to be unresponsive…The thing is that without engine analysis, people who are not experienced enough could not check their games in a timely manner - also it allows so many cheaters to enter the leaderboard (as far as I know). I honestly hope that they can add engines just like lichess do - it is far more anti-cheating and helpful to newbies in Atomic.
Hello everyone. I was wondering, probably, if it's possible to add some engine to analyse and evaluate each position on the board after game? Maybe creators and moderators would answer to this question. Also, I think other variants such as horde don't have any engine to analyse the game. So, I guess it would be really helpful for all chess players who are playing atomic chess and other variants.
