What do you say about durkins attack?

This is an opening i played only once in a chess game (and won). I wonder if is this worth the losing of tempo and just if you like this opening.

The opening for everybody who didn't hear about it (I think most of you):

Then what do you say?

1) not worth the losing of a tempo, --  I don't like it,  --  and never play this as white,  --  is rarely played I think.

2) 1. ... e5  or 1. ... d5 is equal, pending on what you normally like as black.

3) I should play 2. ... d5 instead of 2. ... Nc6 to gain space and to hinder him.

4) Robert Durkin of New Yersey (1923) played this Na3 a.o. in many correspondence games ; someone who is playing this more often, usually knows the sequences to follow, --  and that costs black a lot of time to find out, important in over-the-board games

5) By the way : it is the Durkin Opening, not an attack...

I thought this was the Saragossa opening??

@mcjpd: I believe Saragossa Opening is 1. c3.

I stand corrected 

1.Na3 is the Sodium Attack (derived from "Na")

It's not worth its salt. Though there are interesting lines in other openings where the N goes to a3:

1. Nf3 d5 2. c4 dxc4 3. Na3 is common in the Reti. But this is after the center has had a brief dust-up.

When I play this opening, which is quite often, I have learned to play 2. b3 if black plays 1...e5. It helps develop pieces faster and keeps from moving the N all over the board. I have played over 300 Durkins opening matches and have won close to half of them in my career.

Who the hell is durkin, and what time does he open?

Greetings Sir,

(1) Durkin's Attack does not lose a tempo, it just does not invest it specifically. This may seem like a contradiction in terms but you can not assume it to be a lost tempo until Black shows his hand with his method of attack (and or defence). For arguement sake: 1.Na3 d5 2.Nf3 c5 3.c4 d4 4.Ne5!? Is the Vulture with an extra tempo or 4.e3 Nc6 5.exd4 cxd4 6.d3 is a Benoni with an extra tempo.

(2) To say 1...e5 or 1...d5 against Na3 renders an equal position pending on what Black plays , for what it is worth, is misleading. It presupposes that (a) 1.Na3 induces a signifcant weakness (b) 1.Na3 is ENTIRELY a wasted tempo and (c) there is no relevant follow up to 1.Na3 for White. (a) is a moot point based on the fact that Black hasn't moved yet. (b) is simply wrong which means (c) is a matter for analysis and debate.

(3) >I should play 2. ... d5 instead of 2. ... Nc6 to gain space and to hinder him.<

In which case 1.Na3 e5 2.Nc4 d5 is simply meet by 3.Nxe5

(4) A while back I researched and wrote an investigation peice on Robert Durkin and his attack for a web newsletter (Following the plagiarizing of one of my articles by the editor of this toilet paper I will no longer write for them). According to an article written by FM Alex Dunne of the US, Durkin's rating at one stage crossed the master threshold of 2200 elo

(5) A matter of semantics, 'BCO 1' refers to it as an attack while 'The Oxford Companion to Chess' calls it an opening.

Thank you
