PGN score annotation tags wv and bv

Post by Dann Corbit »

I have seen games with score annotation tags of wv and bv.

For instance, here is a game that uses wv from TCEC:

Who is the inventor of this nomenclature? Is it documented in a standard or at least a manual somewhere? I guess it comes from a chess GUI like Shredder or Chessbase, but I am only guessing. I looked in the pgn extension proposal:
http://www.enpassant.dk/chess/palview/enhancedpgn.htm
and did not find it there.

Also, I have seen games which use bv= also, but I cannot seem to find any right now. Can someone provide a sample game that uses bv for the score from black's perspective?
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Who is the inventor of this nomenclature?
Probably Martin.
Is it documented in a standard or at least a manual somewhere?
Probably not documented as the comment is already clear, also this is part of a comment so practically you can do anything about it to suit your needs.
I guess it comes from a chess GUI like Shredder or Chessbase, but I am only guessing. I looked in the pgn extension proposal:
http://www.enpassant.dk/chess/palview/enhancedpgn.htm
and did not find it there.
ChessGui GUI can output similar to this. cutechess by Jeremy can probably also output something like this. Martin use this move comment info to show in different parts of a webpage including the charts.
Also, I have seen games which use bv= also, but I cannot seem to find any right now. Can someone provide a sample game that uses bv for the score from black's perspective?
When black to move just change the score sign and label it with bv. Writing a script to convert wv to bv or add bv altogether should not be difficult. Or modify the cutechess of Jeremy changing wv to bv, or request Matthias to modify chessgui output.

Jeremy's github repo.
https://github.com/jeremybernstein/cute ... its/master
There is verboseplus and nTCEC branches maybe one of them has wv. I have not tried compiling it.

I the idea "ev" for engines-point-of-view and "wv" for whites-point-of-view came from Martin TCEC. I had it only as a visual aid in ChessGUI, then Martin came along and urged me to put it in his PGN files.

I don't think I did any "bv".
My engine was quite strong till I added knowledge to it.
