Nowhere!
I did not mean mate in e7 in the second sentence. It was a "Lapsus"
after typing the first sentence. I meant mating attack (after taking in e7
and/or in combination with f6 or fxg6 etc.).
Anyway, it is not correct what I meant!. I did not see that Qc5 threats Nf5+!

Still the position is very promising for White, I think, if you let me change
the PV. I will need to check thouroughly but
1.b4 Qxb4
2.Qh6 Nxd4
3.f6 (better than Nd5?) Ne6
4.Nd5 creates a lot of problems to black. After Qc5+
5. Kh1 the threat is fxe7 - Nf6+ and that looks good. A quick check with
Gaviota from this position seems to confirm this.

Anyway, 1.h3 is straightforward. if Be2 2.b4! Qxb4 3. Rfb1! is directly winning
a piece. However, a cook (or more, P. Berger Qh6 looks interesting too)
might exist here.

Regards,
Miguel
