A game analysis and how to read it

This is an analysis of the second game of the 2001 World Championship final between Raphael Schreiber and Brian Rose. Below to the left, you find an applet in which you can replay the game. Below to the right you find the moves of the game as well as WZebra's analysis of it. The columns of the analysis have the following interpretation:

Move number.

The move actually played in the game.

Zebra's evaluation of the move played. This value is the estimated number of discs that the player wins with if he/she plays this move. E.g. "+4.1" means that Zebra think that a probable outcome is 34-30 or so for the player to move.

The sequence of moves that Zebra that thinks is the best for both players from this position. This sequence may or may not begin with the move actually played, sometimes Zebra disagrees with the move played.

The evaluation of the move sequence in Analysis. If it differs a lot from the first Eval, then Zebra thinks that the move played in the game was a blunder. A number with two decimals, e.g. "+1.38", is a heuristic evaluation of an opening or midgame position. An integer, e.g. "-8" is a proven endgame result - "-8" is a proven loss by 8 discs, or simply 28-36. There are some special values: book means that the line is in Zebra's vast opening library, win and loss mean that the position is a proven win or loss resp. for the player the move.

The lookahead (number of moves) used to derive the Analysis. The higher this value, the more accurate the evaluation.

Below the game you find some comments about the analysis.
