Weaver Warren Adams (April 28, 1901 – January 6, 1963) was an American chess master, author, and opening theoretician.
[9] Adams' greatest competitive success was winning the 49th U.S. Open, held in Baltimore in 1948, for which achievement he appeared on the cover of the August 1948 issue of Chess Review magazine.
[10] Adams played in the 1950–51 Hastings Christmas Chess Congress, but finished 9th out of 10 players with 2½/9 (two wins, six losses, one draw).
[11] Grandmaster Larry Evans wrote that Adams' "tournament results were damaged by his dogmatism.
Playing under the self-inflicted handicap of arming his opponents with advance knowledge of his 'best' lines, he felt honor-bound to steer straight into them even though his adversary invariably had a cook up his sleeve.
Ultimately giving up on the Bishop's Opening, he switched to the Vienna Game, claiming a win with White after 1.e4 e5 2.Nc3 Nf6 3.Bc4 Nxe4 4.Qh5 Nd6 5.Bb3 Nc6 6.Nb5, a sharp line that has since been dubbed the Frankenstein–Dracula Variation.
He explained his repudiation of 6.Nb5: "it is antipositional to move a developed piece a second time, and masters have long given it up as hopeless.
[21] Larry Evans wrote that "Mr. Adams and his cronies may be linked to the radical right wing of chess.
[24] Although Adams was rarely successful at the top levels, his ideas were studied and sometimes adopted by strong players.
Future world champion Bobby Fischer scored notable wins using the Adams Attack against the Najdorf Variation of the Sicilian Defense: 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.h3!
[30] Here is a game Adams won using the Albin Counter Gambit, a favorite of his, against National Master Erich Marchand, after White made an oversight on move 13.
