ABSTRACT:
A clock, especially suitable for playing the game of chess, includes the standard two clock face system with an activation button for each player. A delay feature is included so that there is a delay between the time the activation button is pressed and the time that the activated clock actually commences movement. The benefit of the clock is to reduce the likelihood that a player with positional and/or material superiority will lose a match solely because of the expiration of time on that player's time clock.
