.3-D Clock Chess possesses an extensive and objective series of messages. On the top left we have the clock that will inform us of the total time consumed by the players in the game. We also have another digital clock located in the center that gives us the elapsed time and the time for each move made by the player and the program. Below the first clock the information we find is ANALYZE, which notifies us of the best move made so far. Below VALUE reflects what the program thinks about our game. A + sign means that the computer is winning, a - sign means just the opposite, that we are winning. NODES, communicates the number of moves analyzed so far by the computer. I PLAY, indicates the movement made by the program. MOVEMENT, informs of the phase that the game has reached. LEVEL, represents the number of steps that the program has analyzed. Below this appear the last movements made by us (on the right) and those made by the program (on the left). LIMIT, is the time determined by us in the option "Another game" to fix the level of game. I HAVE, is the time in which the program will try to make its move.

Pressing the key that displays all our possible options during the game, we observe the following and interesting menu: change the level of play, return to the previous menu, the computer advises a move, the computer makes our move, display the last 62 moves, invert board, display moves it analyzes, select automatic play, copy the screen on the printer, activate sound and display board coordinates. The latter do not appear initially, which can be a difficulty for the inexperienced.

Returning to the previous menu, and choosing the option to start a new game, a three-dimensional board accompanied by two clocks makes its appearance on the screen, which will control the time spent by each of the opponents.

Previously we will be asked about the level of play, the type of game, normal or problem, and the color of our pieces. In problem mode, the program will request the number of moves in which we want Clock Chess to checkmate.

In the same way, before starting a simple game we will enter the time in which we want the computer to answer us, whose minimum is five seconds. The program allows, of course, to record the game on disk and continue it at any other time.

A curious detail of this program is the option to be able to print during the game all the screens we want.

In general, 3-D Clock Chess, gathered the necessary quality to become one of the best chess programs on the market, being this very good, interesting and easy to use. If you think you have a relatively high level in this, the most curious of sports, face against your PCW, the swords are all over the high. Take a risk!
