I think it was just your connection. Also, you can't name and shame in the forums. If you really think he was cheating (which I doubt he was), you can report him.

Cheaters are banned when they are detected. There are various tools that are used to keep them from returning without permission; these tools are familiar to anyone who has run an online forum.
However, discussions of cheating in the main forum is not permitted, as it tends to become very heated and result in lots of public accusations, many of which are completely unfounded and, if aired in public, it would just cause an ugly flame war. I am therefore locking this post.
To report a suspected cheater to the Support team, please select Report Abuse under the Help menu, or use this link: https://support.chess.com/customer/portal/emails/new. All reports are investigated, even if there is no immediate visible action.
To discuss the matter of cheating further, or to learn more about cheat detection, please join the Cheating Forum: https://www.chess.com/club/cheating-forum
