Gn 2   -   CLASSIC BISHOP SACRIFICE: 

This position shows a variation of the classical Bishop's sacrifice which comes out of a French Opening. By 
sacrificing the Bishop, White destroys the Black King position and then engages in what is known as a “King hunt”. 
When Black plays the French defense in particular it is always wise to keep a lookout for the possibility of this 
sacrifice.

Gn 4   -   PHILIDOR's LEGACY: 

This pretty mating idea has been known since the time of Philidor (late 18th Century). The finish is a pretty 
smothered mate following the Queen sacrifice.

Gn 5   -  MORPHY MATE: 

This position comes from a famous game played by Paul Morphy versus the Duke of Brunswick and the Count 
Isouard during a performance of “The Barber of Seville” in 1858. The culmination of the attack is a strong statement 
of the importance of development. Paul Morphy's superior development crashes though in fine fashion.
