The Perreux Variation of the Two Knights Defense

La variante Perreux della difesa due cavalli mi interessa particolarmente perché derivabile anche dal gambetto Urusov: 1.e4 e5 2.Ac4 Cf6 3.d4 exd4 4.Cf3 - e ora se 4... Cc6, allora 5.Cg5

The Perreux Variation of the Two Knights Defense

"The Perreux Variation of the Two Knights Defense typically arises after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d4 exd4 5.Ng5, or by transposition from the Urusov Gambit. Its name probably derives from the chess club of Perreux-sur-Marne (cercle du Perreux), just outside Paris, where it first became popular in the 19th century. Its sharp tactical themes are easy to grasp and make it attractive to beginning players, but it has also been played by masters who like that many lines lead to interesting endgame positions where good technique can win. As a forcing line, the Perreux Variation also has the advantage of limiting the number of subvariations, so the amount of opening theory is not large. Black is immediately forced to defend his f-pawn by either 5....Ne5 or 5....d5 "
