Fischer - Geller Bled 1961: Hoist with his own Petard

Efim Petrovich Geller (1925– 1998) was a Soviet chess player and world-class GM at his peak. He won the Soviet CH in 1953, 1956, 1962, 1965, 1968, and 1971. He won four Ukrainian Championship titles (in 1950, 1957, 1958, and 1959) and shared first in the 1991World Seniors' Championship, winning the title outright in 1992.

Geller was also a coach to World Champions Boris Spassky and Anatoly Karpov. He was also an author. Geller is reckoned to have been among the best ten players in the world for around twenty years. His total score vs six World Champions is +37 -31 =124  https://en.wikipedia.org/wiki/Efim_Geller

As was his wont, Geller gambles with 7...Qf6 in an attempt to assume an early offense. To thwart this manuever, part of a patently prepared line, Fischer sacs a pawn (9.d4). Undaunted, Geller tries to attack. But it backfires. With a series of rapier-like thrusts, Fischer demolishes Black in a mere 22 moves.

Subsequent attempts to improve on Geller's play have failed. Thus, this fruitful encounter offers what has come to be accepted as the refutation of Black's ultra-aggressive system                       GM Larry Evans (introduction to Game 29 in My 60 Memorable Games)
