In books etc. use the move that change the score between += and = normaly be
annotated as ?! (dubious move).

In my first chess-program I own (Zarkov 2.6 by Stanback) he was giving this
change a score of 0.2 pawn value. He gives the score between '+/-' and '=' to
0.6. (+/- -> White is clearly better or White has the upper hand.)
In normal language this change between +/= and = could be writen 'white stands
slightly better' and 'even'.

The use in Chess Assistant seems to be between 0.4-0.5 pawn value but they have
added a definition between these two scores (+=/=). I haven't tested the CA
score because I always use symbols when analysing to not be disturbed by the
small decimal changes.
