Scotch Opening - How to play Does anybody have some indication of a book, site, video, etc,, which explores this variation of Scotch Opening for Black? 

[fen ""]
1. e4 e5 2. Nf3 Nc6 3.d4 exd4 4. Nxd4 Bc5 5.Be3 Qf6 6.c3


I have lost a lot of games playing 5...Qf6. Does there exist some good continuation for black here? If not, what should be the alternative to 5...Qf6?
I'd recommend Starting Out: The Scotch

It covers everything the Scotch has to offer, and it is written by an expert player in it.

Like the rest of the Starting out Series, it explains everything you will ever need to know on the opening. It offers great tips on whatnot. 

There are lots of sources for minor stuff. Chess Caffe is a great source.

Also playing makes you understand it more. Hope it helps!
