Yes, but that looks like about the worst possible case for White to test the usefulness of his a3 versus that of ...Nc6.  After 5. Qh5 Black can play e.g. 5...Nd6 6. Ba2 g6 7. Qf3 Nd4 8. Qd5 Qe7.

I would presume that 4. Bc4 is well-met by 4...Nxe4, and 4. f4 by 4...d5.

Why 4. Nf3. I'd rather Bc4 or f4...

I advocated 3...Nc6 4.Nf3 Be7 as a safe way to equality. There is no need to hurry with d7-d5.

Back at school most of us seemed to prefer language to algebra, so... but if youinsist : 1. e4, e5 2. Nc3, Nf6 3. a3!? (Or 1. Nc3, Nf6 2. e4, e5 3. a3!?)

Put some more effort into your questions and I may put some more into my answers. For instance some moves would have been nice as some Openings lines are referred to by different names depending on which part of the Globe you live.

If you are indeed referring to 3.a3 as others have mentioned, then there is no refutation, as 3.a3 is a useful move in many e4-e5 Openings and perhaps more importantly does not harm White's position. White is simply playing as Black with an extra tempo while at the same time avoiding Black's most testing response, namely a reversed Ruy Lopez. The line is not as innocuous as first appears and black must exercise some care in order to equalize.

I would recommend that Black head for a reversed Scotch Game as this seems to be his most solid and reliable answer:

1.e4 e5 2.a3 Nf6 3.Nc3 Nc6 etc. or the alternative move order 1.e4 e5 2.Nc3 Nf6 3.a3 Nc6 intending 4.Nf3 d5! with an equal game.

I think that 3...d5 is dubious because of 4. ed Nxd5 5. Qh5, since Black doesn't have recourse to ...Nb4.

Actually there are a few variations of the scotch four knights where, if black had a pawn on a6, there would be a promising alternative involving the bishop retreating to d6 I believe, so a6 as white would come in useful with a scotch.
I'll try to dig the exact line out. 3...d5 certainly is no refutation though, and the scotch is known not to give white an advantage with best play, so I'd imagine white is happy with this.

Wasn't our previous conclusion that black should play a Scotch with 3...d5 as white's extra move a2-a3 wouldn't be too relevant in that opening? I advocated 3...a6 but then white can play 4.d4 instead...

There is no refutation, black's basic plan is to show that 3.a3 is a wasted move, when he will have equality. However 3.a3 is not a weakening move and can be useful and therefore it is a fully playable move.

Craig

Thanks, that's really very helpful : I'll contact Bondarevsky immediately !

As every Russian school boy knows, the refutation is the Bondarevsky counter attack.
