Chess.com had bid difficulties with our server. We couldn't play online chess without internet problems. Lichess came in and solved it all.

One more thing I would like to add was that I benefited financially when lichess came out as I reported bugs to @utopian back then on steemit.

If my contribution was okay, I was upvoted well. Lichess being an open source helped me alot.

They have been great ever since, Thanks for writing about them. You are right, we just play and forget them :)
