OPENING LINES

Just a short T-Notes this week. This issue is also a bit early, as I'll be at RFK Stadium on Sunday the 21st watching DC United whup up on the Tampa Bay Mutiny.

I'd like to take this opportunity to remind you that Electronic T-Notes is your publication. Please write to me with your suggestions for topics that you'd like to see covered in upcoming issues. You'll find a link to my e-mail address at the end of every issue of Electronic T-Notes.


EVALUATION COLORS IN FRITZ4

by Steve Lopez

I'm still awaiting my copy of Fritz5, so this week I'll take a step back and answer a question about Fritz4.

Many people have asked for an explanation of the colors in the evaluation profile of Fritz4. To be honest, this feature is not at all intuitive and does require a bit more explanation than is provided in the Fritz4 manual.

I fired off a letter to Mathias Feist, co-programmer of Fritz4. Here is his reply, with my additional commentary given in brackets:

"The bar graph gives the evaluation [in 100ths of a pawn]. Red means the engine has an advantage, the height of the bar denotes the amount of the advantage. Green bars show the advantage to the user [i.e. the user has the advantage]. Yellow bars denote an advantage (or disadvantage) bigger than the maximum scale of the window, which is + or - 9.0 [in other words, add or subtract 9.0 from the number given in the upper left corner of the evaluation profile window]."

Additionally, if the bar is above the center line, it means that White has the advantage. A bar below the center line means that Black has an edge.

What the evaluation window does is provide you with a picture of the game's "ups and downs" at a glance. Unfortunately, when you save a game, the evaluation profile is not saved along with it in Fritz4. I understand that the profile will be savable in Fritz5.
