Turbo Chess is a tiny program (it doesn't reach 100 Kb.) That allows you to play some chess games facing other players through a direct connection. One of the players will be the host, who has to invite the other player. The latter can only access the game as a client using the same IP as the host.
Being so small, it is logical that Turbo Chess cannot offer too many benefits, but it is always an entertaining way to hang out playing chess. It includes a Chat that will allow users to comment on the progress of the plays. It also has a history that can be consulted to study the movements made. In addition, you can save the disputed moves to study them carefully, and find out where you failed or where you hit.
The problem with Turbo Chess is that it does not allow you to play against the computer, which means that there are always two online players available to play a game. Still worth a try.
You can free download Turbo Chess 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
