The reason no one can find a name for this opening is, I think, because there is more than one dubious move here. First of all, 3. Nc3?! You don't usually want to block your c-pawn as White when opening with d4. The only virtue of this move is that it can support an e4 advance, which is why here I think Black should play 3... d5! Now I suppose we would be in some sort of London system, which should be harmless for Black. Or, if Black prefers to play 3... Bg7 and allow 4. e4, then instead of 4... d5?! Black could have played d6 and suddenly we have a main-line Pirc. I don't like 4... d5 because after 5.e5 Ne4 6.Nxe4 dxe4 I think Black will be hard-pressed to hold onto the e4 pawn in the long-term.

So, basically my analysis would be that White made a dubious third move, but that Black failed to take advantage of this on his third and fourth moves and as a result White got a nice game. The final position is rather interesting however, and unbalanced enough that either player can still have good chances.

After writing the above I've looked at the line a bit more with Fritz; one other possibility is instead of 9.Be3, White could try 9. e6! with the idea 9... Bxe6 10. Nxe6 fxe6 11. dxc5.

No, I used chess base, the on-line version.

a bigger data base might have some more games.
