Although chess can be played online, it is best played over a board. To get even more out of the games, I have created a webapp to record the moves along the way. It is designed for training and friendly games and give you the stockfish evaluation. However, not the actual variation. What the best move is, you have to figure out yourself. Unless you decide that you want a number of hints available.
The interface will rotate every half move, so you don’t have to turn the phone/tablet over.
The app is located here https://snart.com/chess. All processing takes place locally, so no data is shared. The source code is open and available at github
