I need to correct things a bit. Actually, it's not Black's 20th move and
White's
first move (1. e4) in the next game that cause the problem. It's White's 20th
move in game 1 and White's 1. e4 in game 2 that can cause this as well as
Black's 20th move in game 1 and Black's 1st move in game 2. I just saw an
example where 1. e4 is rated as within the blunder threshold but 1... c5 was
more than 0.5 worse than the previous game where Black's 20th move was highly
rated by the engine.
Hope that's clear...

Subject: SCID - Annotate using "find opening errors" - bug
I took a collection of games and wanted to analyse the openings (defined by me
as first 20 moves of a game) of the games in this particular database. I
selected "find opening errors" and set that parameter to 20. I also set the
blunder threshold to 0.5 pawns. I set the options to analyze both white and
black moves but to not analyze any variations that may be present.
As the engine (Stockfish-1.9.1 in my case) analyses away, when it moves from
the
end of one game (it has analysed the first 20 moves of the first game and thus
skips the remainder of that game and starts analysing the next game in the
database. Sometimes the eval generated for the first move of the second game is
significantly different from the eval of the previous game's last analysed
position (black's move 20 of game 1 had eval of 0.8 for example and white's
first move of game 2 (let's say the move is "e4") is perhaps 0.2 and this
triggers the "this move (1. e4) is a blunder because it is more than 0.5 pawns
worse than the previous move.
This obviously is a bug and I would appreciate thoughts as to when this might
be
fixed.
Thanks,
Roy
