No, each informant comes with a handy legend/bookmark. The legend has explanations in multiple languages for all the symbols used.
That was true last time I bought one, anyway.
p.s. Don't worry about the ECO codes, knowing these won't make you play any better.
p.p.s. Informant is rather expensive and really dry. At your rating it will quickly become a doorstop, get something else.
hello group
could somebody help me with this- if you looked at chess informant there are codes for openings
do i need eco to understand informant?
thank you
