History

The Fried Liver Attack has been known for many centuries, the earliest known example being a game played by
Giulio Cesare Polerio Giulio Cesare Polerio (c. 1555, – c. 1610; reconstruction of places and dates by Adriano Chicco) was an Italian chess theoretician and player. Name affixes used for him are ''l'Apruzzese'', Giu io Cesare ''da Lanciano'' (Salvio/Walker), and ...

programs, including those on large mainframes, were reportedly still vulnerable to the attack in 1980.

recommended, but Black is quite strong after 9.a3 Nxc2+ 10.Kd1 Nd4 or 10...Nxa1! 11.Nxd5 Qh4! when White's attack runs out (12.Nxc7+ Kd7 13.Qf7+ Qe7 and the queens come off; after 12.Nb6+ Ke7, 13.Nxc8+ is met by 13...Rxc8 14.d3 Kd8, and 13.Qf7+ is met by 13...Kd8 14.Nxa8 Bd7; either way, Black's king is safe and Black has the advantage). Thus, 9.Bb3, 9.Qe4, or 9.0-0 are better choices. White has a strong attack, but it has not yet been proven to be decisive. Because defence is harder to play than attack in this variation, the Fried Liver is dangerous for Black, particularly with shorter
