Manual Revelation II

The display
The left side of the display shows a chess board with the position of the pieces that is used by the
computers chess engine. When the physical chess pieces are not moved correctly the position on the
display may not be the same as the position on the Revelation II board. Blinking LEDS on the board
will indicate the differences.
In the display the solid, light chess pieces represent the white chess pieces on the board and the
open, darker pieces in the display represent the black pieces on the board.
The first two top lines display general information, in below picture the first line indicates the move
by the computer. The second line shows a hint for the player. You can switch off this hint information
if you wish. (See Extended Option: ‘ENGINE OPTIONS’ on page 17 of this manual)
Lines 3, 4 and 5 give information about the engine in 2 blocks (left and right).
The left block shows the current variation under investigation. In brackets is shown the expected
move by the human player followed by the moves calculated by the computer.
In the right hand block the best move for the current evaluation is shown (calculation in progress). In
this example the computer calculates the evaluation is -0.40 (1 pawn equivalent = 1.00). This means
the computer values the position favorable for the human. (a negative value means a disadvantage
for the computer).
The next line of the right block shows the move that is now under investigation (e8g8) and that this is
the first move investigated in depth 11. The number 11 is the depth in half plies which were
completely investigated. The number 30 indicates that the engine has also searched 30 half plies
deep for specific positions (mostly capturing variations).
In chess computer terminology: the engine has evaluated 11 half plies brute force, and 30 half plies
selectively.
The 3
rd
line of the right hand block shows the total number of evaluated variations / nodes and the
evaluated variations / nodes per second. If a K is added it means the number is in multiples of 1,000
nodes. So 2370K means 2 million 370 thousand positions searched in total. Same applies to M for
multiples of 1,000,000 nodes. The smaller number 0119K signifies the average number of
investigated positions per second.
You can hide the information about the engine by pressing LEFT or RIGHT. The display does not show
relevant thinking information then so you can play without seeing what the computer is calculating.
The large digits at the bottom of the display show the elapsed thinking time for the player with the
White pieces on the left and the elapsed thinking time for the player with the Black pieces on the
right. These digits will always count up.
