I've had this idea in my head for a couple of years but today I got to play it for the first time:

1. e4 e5  2. Nc3 Nf6  3. f4 d5  4. fxe5 Nxe4  5. Nf3 Bb4 and now 6. Nb1?! 

I hadn't even conceived of the following "trap" but it is precisely what my opponent fell for (albeit in a 3-minute game):  6...c5??  7. c3 Ba5  8. d3

More critical would seem to be 6...0-0 or 6...Bg4 but then I like the idea of simple development by White with Be2 and 0-0, and then ejecting Black's pieces with c3 and/or d3.  Possibly Black's best as in a lot of these lines is ...0-0 followed by ...f6

Nice idea. Probably 6.Qe2 (mentioned by MNb) is objectively better, but 6.Nb1 is quite interesting. I'd suggest 6.Na4!? as a slightly stronger alternative. The idea is similar to Nb1, but it controls the square c5.


Sorry to necro this (I'm returning to the Vienna after 4.5 years with the Spanish), but whereas I no longer think 6.Nb1?! or 6.Na4!? are especially good, White has 6.Bd3 and if 6...Nc5 7.Be2 Ne4?! then 8.Na4 might be worth a serious look e.g. 8...O-O 9.c3 Be7 10.O-O

Unfortunately, there is 5...Bc5, mentioned by MNb, and 5...Be7 is another problem.

To lure the bishop to b4, years ago I analyzed 3.a4!?. If Black replies 3...Bb4, we have the Popov Variation of the Spanish Opening with an extra tempo: 1.e4 e5 2.Nf3 Nc6 3.Bb5 a5!?. By the way, Mr. Popov's 4.0-0 [4.c3 f5] Na7 is dubious according to Lev Gutman, but I'd like 4...Nd4, a version of Bird's 3...Nd4. The move a7-a5 is useful.

For adherents of Bird's 3...Nd4, even 3.Nd5 in the Vienna can be an option (3...d6 4.Nc3 d5 Scotch; 4.Nxf6+!?). Not worse than the Fyfe Gambit...

I would be tempted to play 6...Bf8!?

Except that White has lost two tempi with Nb1-c3-b1. Black can use them eg by transferring the bishop to b6.
What's wrong with 6.Qe2 Bxc3 7.dxc3 0-0 8.Qe3 ? Two Bishops, halfopen f-file, better control of the centre. I would love to play this as White.
My main problem is 5...Bc5.
  

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.
