Automatic Analysis

Most chess engines can analyze your games automatically. Either a single game or a group of games in your database can be analyzed. Time for each move to be analyzed can be chosen. More time is required to analyze master games while a few seconds per move is sufficient for beginners’ games.

The game given below is analyzed with ‘Rebel Tiger II ‘ with a Pentium 500MHz computer with  192MB RAM.

Only 30sec per move was selected and here we have an amazing quality of analysis.

  9.Ne5

{Score: 1.34   depth: 12      Nb5 Qd8 }

Move 9.Nb5 is recommended as it has an evaluation of +1.34 meaning that it is advantageous to the extent equivalent of winning one and one third of a pawn. The average depth is 12 ply, meaning 6 full moves for both sides.  Rebel engines indicate + score when the side whose first move is shown has advantage. Chessbase engines indicate + to show white is better off while negative score to show black is better off, irrespective of the side to move.

    [Thirty seconds to produce a gem!
    Instead of the actual move 11.Qb3 , if 11.e4 was made white would have been two and a half pawns better off.
    See how a pawn can be sacrificed to keep the white queen in an attacking position while the black bishop's defender can be distracted using
   
the tempo gained on attacking the black queen!]

But, if the knight is going, let it go after storming at the white king's castle and creating some weaknesses.]
