''XBoard'', also known as '''''WinBoard''''' on Microsoft operating systems, is a Free Graphical User Interface Client developed by Tim Mann that is compatible with various Chess Engines that support the Xboard Communication Protocol such as '' GNU Chess ''. It also supports Internet Chess Server s, E-mail Chess , and the playing of saved games.

A notable feature of this software is that it doesn't allow chess servers to monitor window input switching, one of their anti-cheating mechanisms.

A notable alternative protocol is the Universal Chess Interface (UCI).


TIMESEAL

The Timeseal program was an add-on for XBoard/WinBoard (though it supported other interfaces as well.) It was designed to solve the problem of network latency introduced in short (blitz/lightning) games. Timeseal would record the actual amount of time the player spent making the move and send that to the chess server. Without it, network latency time would be added, giving a significant advantage to users on faster connections.

Timeseal introduced a security hole with XBoard/WinBoard. It kept track of how much time the player spent on a move, and it was running on the player's machine. Thus it could send back an incorrect value. Not surprisingly, this was eventually exploited. A variant of Timeseal appeared that applied a 0.5 multiplier to a player's move. So if a player took four seconds to move, Timeseal would report that they only took two seconds.
