Davies, Nigel. Play 1.e4 e5! A Complete Repertoire for Black in the Open Games. Everyman 2005. 156-161.

Davies recommends the traditional Spanish Four Knights from the Black side with good coverage over two games.

Emms, John. “The Spanish Four Knights.” Play the Open Games as Black: What to Do When White Avoids the Ruy Lopez. Gambit 2000. 142-158.

Emms recommends Rubinstein’s 4…Nd4, for which he offers excellent coverage. This is one of the few sources to take 5.O-O seriously as a significant variation.

Evans, Larry M. and Ken Smith. An Unbeatable White Repertoire After 1.e4 e5 2.Nf3. Chess Digest 1988.

Seeing this book suddenly back in print was the first thing that got me to take the Four Knights seriously again. Evans’s coverage of the main lines is very fair and balanced (if occasionally dated) while Smith offers a good standard treatment of all Black alternatives after 1.e4 e5, finding an advantage for White at every turn. This is an excellent repertoire book for anyone interested in the Four Knights.

Kaufman, Larry. 327-342

Kaufman recommends the odd-ball 4…Bd6, which he claims leads to equality.

Pickett, L. M. Four Knights and Belgrade Gambit. Notingham: The Chess Player 1976.

This 80-page pamphlet devotes nearly half its pages to the Belgrade Gambit, yet it does a fair job of covering the main Four Knights lines. I always like to look at older materials as they often discuss lines that current works take too much for granted

Pinski, Jan. The Four Knights. Everyman 2003.

I must say that I was very disappointed in this book and consider it practically worthless for anyone interested in learning the traditional Spanish Four Knights lines, which receives a scant 9 pages of coverage, while the Scotch Four Knights, Belgrade Gambit, and Glek System (with 4.g3) receive over 40 pages each. Also, his coverage of Rubinstein’s 4…Nd4 completely leaves out 5.O-O.

Nunn, John. New Ideas in The Four Knights. Batsford 1993.

This may well be the best book on the Four Knights ever written, with an excellent division of the material and choice of games.
