tafl,

I agree wholeheartedly with you.  There seems to be a trend here lately to throw in a2-a3 as early as possible and then try to create lines to study. 

As far as I can tell, the main point of White playing an early a3 is either to get away from computerised analysis or to get out of bookish openings. 

In either case, spending a great deal of time on this when much more challenging and common opening ideas are out there doesn't make much sense to me. 

Then again, I'm something of a classicist at heart and like the idea that the three main goals of any opening are: develop your pieces (especially your minors), protect your king, and control the center.  I don't see how an early a3 solves any of those main issues in most lines.

Kaissiber 20 has a long article on the Halloween Gambit (p22-51), and mentions briefly that white has even tried 'Die Verfeinerung 4.a3', giving the game Carlsen-Nyysti Finland 2002 as example. (see link below)

(Yes, it's *the* Carlsen, though in 2002 his rating wasn't all that terrifying yet - still, it's an indication that the whole idea might not be all that dubious...)

http://www.shakki.net/4si/games/gra2.html

Btw, Kaissiber also contains a report from a corr theme tournament, and the theoretical improvements found as a result of it.

One point of 4.a3 g6 5.Nxe5 is that the knight retreat to g6 was the defence that scored best for black (Ng6 + 7...d6 +2 =4 -12 and Ng6 + 7...d5  +0 =4 -6 (from white's point of view)) and obviously that ain't possible with a3 g6 inserted...

PS: When I give 7...Bg7 an exclamation mark, it's purely a practical solution. If you like to invest a lot of analysis in a peripheral line, 7...Nb8 probably should objectively be annotated "7...Nb8!! -+"

There are lots of names and lots of analysis.

However, it's utterly harmless after 5...Nxe5 6.d4 Nc6 7.d5 Bg7! 8.dxc6 bxc6, which is almost identical to 4...d5 5.exd5 Nxd5 6.Bg2 Nxc3 7.bxc3 (which again is identical to 4...Nxe4 5.Nxe4 d5 6.Nc3 d4 7.Bg2 dxc3 8.bxc3).

It is hard to imagine how the extra a-pawn move may become significant.

Has anyone come across this interesting looking sacrifice? Does it have a name and does anyone know of any analysis?

1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.a3!? g6 5.Nxe5!?
