 Jaffe became involved in a 1916 court battle against 'American Chess Bulletin' co-editor Hartwig Cassel, involving the non-inclusion for publication of some of his chess analysis of the King's Gambit, Rice Gambit, but he lost the case, despite being supported by witnesses who included U.S. champion Frank Marshall.This was apparently the first American case where chess matters made it to the courts.While seemingly frivolous, this case should be viewed from the perspective of Jaffe making much of his living from writing articles on chess for Jewish periodicals, so his professional reputation was at stake.
