Na3 as a first move also simply allows black to take the center with ...e5 or ...d5, so white would want to prevent this first by playing something normal like d4 and then into the london system.

Na3 is known as the Durkin or Dunst opening--playing a bunch of useless games on the Internet is not going to get an opening name recognized.

On a side-note, how can we call Na3 the Tapel-Tomas when it is already the Sodium Attack?

Na3 is the atomic name for sodium. And I already explained how to get it recognised as an opening.

Well, the 'atomic name' for sodium is... sodium. Na is the chemical symbol. And it IS the name of the opening- the recognised name. Nobody is going to rename it any time soon.

From that famous Internet source: Wikopedia.....

The Durkin Opening, also known as Durkin's Attack, or the Sodium Attack, is a very rarely played chess opening beginning with the move:

1. Na3

This awkward development of the queen's knight does little to utilize White's advantage of the first move. From a3 the knight does not influence thecenter or possess much activity. It is likely that White will move this knight again soon, perhaps by playing c4 and either recapturing on c4 (e.g. 1...d5 2. c4 dxc4 3. Nxc4) or playing Nc2. If this is White's plan it is stronger to play c4 on the first move (the English Opening). As such, this opening is probably most valuable as a way to avoid opening preparation.

It is named for Robert Durkin (1923-?) of New Jersey. The name "Sodium Attack" comes from the algebraic notation 1. Na3, as Na is thechemical symbol for the element sodium.

The game of which Robert Durkin is named after is posted as the first game in the intro of this forum and many are not impressed,and seconded by my actual game with a National Master.ChessTrainor.

ChessTrainor, I am impressed with your innovation for the London System, just not the idea of playing Na3 as the first move in the London System.

What, showing it to the officials in a FIDE tournament? What do you expect will happen?

There are no official names for openings.

I just move my moves and the more important thing is it is my contribution to chess itself.Coming from and Asian country,where the ancient chess not modern chess came from.Im just happy to contribute.Our site's motto is Play,Share and Learn.Bringing joy to the Five years old who discovered it is a joy to me,The Tomas side of the Tapel -Tomas the little boy  who discovered it and my participation is to develop it to a viable opening that really win games.Being an engineer our role in Society in general ,from the word engineering,is design and constuction.We invented a four player chess game,we design and constructed.fulfilling the engineering side of me.Same thing with this opening,design and development.CT,Just happy to share.If someone gives you a gift or knowledge for free it is up to the recepient what to do with it,the main thing the Giver has given you something it is up to you what to do with it.If in the tournament,you just neglected this opening,a beginner,intermediate,or advancing beginner would have a hard time defending or may eventually loss,it is there, already i turn it loose again Durkin was first because in this site someone is using it already.Like any good player we must prepare for any opening,Bookline or Irregular.same.

Sodium attack is a general term,if you just call it that,the Durkin attack is also called Sodium and is totally different in approach,you would have difficulty of wfhich is which because the durkin attack called sodium follows a different idea belonging to the Bird system,it has F4 ,andmy opening does not have that and does not take on that idea,placing them together is very wrong for my Tapel-Tomas Opening follows The London System-Torre Attack and Colle System, a totally different approach and idea from Durkin.Calling them by the generic name sodium will be very,very confusing,E4 is generally called King's Pawn Opening,To call Sicilian with E4 as King Pawn because of the first move and the French also King's pawn is confusing because their move orders are very different from each other same thing with The Durkin Attack and The Tapel-Tomas.CT

Contribution to chess? AHAHAHAHA. Nice joke lol!!!!

lol

however, chesstrainor has a point. If Black takes it, the open b-file can give White play. If black doesnt take it, c3,Nc2 and d4

I still think taking gives black a slight edge. But it's more flexible to take the center first. As long as you take it seriously, if these odd moves (not just na3) are played you have good chances to win. Just play your best and don't underestimate it. The psychology is the only possible gain from the series of move. If your opponent plays like a normal person after Na3, his position may be fine but black will still be at least equal. It may transpose into a reversed q pawn opening where the knight goes to a6 or some kind of english but it's still rather passive anyway you put it. Although taking isn't as good as it looks, even this seems pretty fine for black as white gets a bishop and b file but black still has the center. Bottom line it just doesn't create enough problems for black.

You all can be jerks, but I will play Na3 in my London System from now on- Nd2 was too cramping for me. Thank you, ChessTrainor, for showing me this. 

ps. I still won't play Na3 as my first move, though.

Now that is smart. I didnt say Na3 sucks. I said 1. Na3 (take note of the number 1) sucks. But still, london system Nd2 isnt too bad

Isn't Nd2 in the london system theoretically better than na3 though?

Theoretically, Hannibal should have conquered Rome and communism is great. Every time I played Nd2 in the London System, I found myself too cramped. Also, part of the London System is a King side attack, which I always difficult to accomplish when the opponent countered in the middle. The Knight on a3 helps keep things relatively stable, but it does compromise the idea of the king side attack.
