It seemed about time to do a Budapest Fajarowicz (A51) Webliography and Bibliography, if only because there has been such a proliferation of good material on this opening in recent years. And the Fajarowicz deserves the attention it is getting, since it is a fascinating line, especially at the amateur level. In the regular Budapest Defense, Black generally recovers his pawn following 1.d4 Nf6 2.c4 e5 3.dxe5 Ng4 since the only way for White to hang onto it is by making major positional concessions with moves like 4.f4?! But in the Fajarowicz with 3.dxe5 Ne4!? Black generally foresakes his pawn and focuses instead on rapid development and tactical threats. Often, after exchanges, Black will eventually be able to recover the e-pawn in normal Budapest fashion to achieve an equal game, but this is rarely the second player's prime motivation for playing 3...Ne4.
The line was first developed by Sammi Fajarowicz (1908-1940), a Jewish chessplayer who lived in Leipzig through the beginning of WWII and died of tuberculosis under the terrible conditions of Hitler's Germany. He played a number of games (not all successful) with the line in the late 1920s and early 1930s (see, for instance, Glig - Fajarowicz, Bautzen 1929).
I became interested in the Fajarowicz rather indirectly from researching the "Reversed Faj" positions that can arise from 1.e4 c5 2.f4 d5 3.Nf3 dxe4 4.Ne5!? and I became intrigued enough to make this an occasional weapon and a third way (besides 1.d4 Nf6 2.c4 d6 and 2...Nc6) of sidestepping lines of the King's Indian when White does not commit to Nf3. I'm not sure the Faj is really sound, but it can definitely be fun and its tactical themes are worth knowing.
As always, I invite additions to this list from readers in the comments section below.

Available from USCF Sales, reviewed by Seagaard, Elburg, and Hansen. By far the most thorough analysis of the Faj, offering useful lines for both players. Though this is an indispensable reference work, especially for correspondence players, it is not what I would recommend to anyone trying to learn the line for the first time. The Faj is actually pretty simple, with just a few themes to learn and a few critical lines, and Gutman's book can be quite intimidating.
