FICGS - Wikichess, open chess repertoire project

1/Played by French amateur chess player Charles Amar in the 1930s, this opening is also known as the Drunken Knight Opening, or the Ammonia Opening (NH3 is the chemical formula of the ammonia).

There is no particular interest in choosing to play NH3, and it is therefore considered as an irregular opening. It prepares for kingside castling, but so would NF3...

2/Here is the "Sodium Attack", an very rarely opening played in profssional tournaments,the interest of this
Non-orthodoxe opening,is to control cells g5
and f4 in One also move... to prépare the attack on column f, with bishop on c1 at thé 3th.move, and to prépare the casting, so of course!
