If you are interested in hitting hard with Black, then Gambiteer 2 may be just the thing for you.
In this straightforward book, GM Nigel Davies presents:
-
the Schliemann Gambit in the Ruy Lopez
-
Albins Counter Gambit (1.d4 d5, 2.c4 e5!)
-
spectacular, yet playable gambits against boring stuff like the English, 1.Nf3 and the Italian
If you like to dictate play from the very beginning, I advise you to take a look
here.
