Ammonia Opening[edit]

1. Nh3[edit]

The Ammonia opening is based on the chemical formula of ammonia (NH3) and the fact that ammonia, like this opening, 'stinks'. An alternative title is the 'Amar' opening (other names are the "Paris Opening" and "Drunken Knight Opening"). Chess author Tim Harding has jokingly suggested that "Amar" is an acronym for "Absolutely mad and ridiculous"; that sums up this move!

It's not bad, it just does not improve White's position, as such it's a wasted opportunity.

Normal replies would be

as this has effectively given the first move to Black (though the Knight may, of course, change the way Black proceeds).


No statistics as 1. Nh3 occurs rarely among serious chess players.
