I have 3 recommendations for you.
If you want a book that covers all lines , but not in too much depth, then 'The Scandinavian Defence' by James Plaskett is a good bet. The presentation is a bit haphazard at times, but it's a reasonable overview of the defence.
If you intend to go down the ; 1.e4, d5 2.e x d5, Q x d5, then a book that may give you an edge over your opponents is 'Scandinavian Defence; The Dynamic 3....Qd6' by Michael Melts . Loads of games, well annotated, by someone who champions this line.
In my opinion, if you want to play for a win ( and not afraid of losing ) then the 2....Nf6 line is well worth investigating. Although a bit dated, get a copy of 'Center Counter Defense; The Portuguese Variation', by Selby Anderson. It covers all white's possible replys, and gives black real counterattacking possibilities.
It will worry most e4 players!!
And don't forget, Capablanca used to play this defence before he took up the Caro-Kan, so it can't be all bad.
I need some help. Can anyone tell me of a good book to read which deals with the Scandinavian Defense? How about a few masters that employ this defense whose games I could study? It's one of the oldest, so there's a lot of stuff. But I'm looking for the good stuff. All suggestions are welcomed.
P.S.
No Englund or Charlick Gambit.
