Hi,
Is in cvs since yestereve. A '!?' nag mark is added for each
move in the game that is stronger than the engine-anticipated
best move; that is, respecting the delta from the informant values.
The (less optimal) engine variation is added in best-move-annotation only.
Cheers,
Joost.

Hm! Of course, there is another possibility!
Due to the horizon effect it can happen that the engine realizes in
hindsight that the game move is actually stronger than the best move he
expected. Such move should probably deserve a '!?' or even '!'
annotation (while possibly adding a '?!' to the best engine line). This
is still marked as TODO in a comment section in the code.
As an example: Analyze the Najdorf sicilian opening moves with stockfish
90 secs, no book of course, in all-moves mode:
After 1.e4 c5 2.Nf3 stockfish expects 2...Nf6 (+0.60) as best move. Once
the actual move 2...d6 is played and the engine is given another
thought, stockfish adds a score of +0.44 to this move, yet annotation
still adds the engine's the best line, which is actually worse than the
game move.
I like it!
Of course this will not happen if you do only blunder annotation.
Cheers,
Joost.
