Internet Chess Club (ICC): currently the best platform for playing exercises with Sharp Endgames. Both players are able to move the pieces on the board, and the chess clock works satisfactory (although this function could be improved).
Playchess: direct access from Chessbase 14, and thus all the valuable features from board notation are kept in a broadcast session.
Skype: in my view, with better sound performance than similar platforms. Has a screen sharing function.
Team Viewer: enabling remote control of another device, thus making support and installation of software easy.
