@CrowChessI use Win XP and at the moment you can play the latest version of Mozilla. But still not visible clock. Therefore, I do not know how to play yet... I will not change the operating system. XP it was the best of all Windows - I have several of them and I can modify them as I please. If the bugs are not corrected, you will have to find a PC specifically for chess. I think playing with the phone is complete nonsense.
@GrimpeurIf you are talking about Linux, you are right. This is more versatile, up to and including the use of multiple virtual OSes on a single machine. But for Windows this is nonsense. Over the past two years malware Petya and other extremely malicious viruses infect all operating systems other than XP. More precisely, it had the least vulnerability to modern viruses, even if you have open ports. And I will not list viruses for Linux. All the latest windows is sorry sucks. The latest version wants 32 GB minimum for a system disk. And it is full of hidden services and other unnecessary and harmful things. Just like android.
I urge people to look at the clones of Lichess and develop them if it is interesting to anyone.
