Chess Opening Theory/1. e4/1...Na6

= Lemming Defence/Mirrored Amar Opening =

1...Na6
The Lemming Defense is a very rare and rather weak opening in response to 1. e4. The knight develops to a square that doesn't control the centre and as such, it's a wasted opportunity.

This opening is very rarely seen among serious chess players, and it's classified under the code B00 (Uncommon Opening).
