Further details on new exciting Vienna line

I was away for two weeks to escape the holiday fuss and have been considering white's chances in the new Vienna continuation I unveiled in my last blog.

By the way, what name should we give it ? Does "De Bouver gambit" sound too harsh ??

Anyway, after 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 Bf5 5.g4 Bg6 6.g5 Nd5 7.Nxe4 Nc6 8.c4 Nb4 9.a3 Qxd4 10.axb4 Bxe4 11.fxe4 Qxe4+ 12.Kf2 Qxh1 13.Nf3, black is fare ahead in material but sees his queen cornered on h1.

I showed that black's only defense consists of 13...Rd8 14.Qa4 e5 15.Be3

White now wins the black queen, so the only question is how much material can black win in exchange for his queen.

After 15...e4 16.Bg2 Qxa1 17.Qxa1 exf3 18.Bxf3, black is still ahead in material and white must capitalize on his lead in development.

a/ 18...Bxb4 19.Bxc6+ bxc6 20.Qa4

...a1/ 20...Bd6 21.Qxc6+
......a1a/ 21...Kf8 22.h4 (+=)
......a1b/ 21...Rd7 22.Qe4+ Be7 23.c5 (+=)
......a1c/ 21...Ke7 22.Bd4 (+=)
...a2/ 20...Be7 21.Qxc6+
......a2a/ 21...Kf8 22.Qxc7 (+-)
......a2b/ 21...Rd7 22.Qa8+ (+=)
...a3/ 20...a5 21.Qxc6+ (+-)

b/ 18...Bd6 19.c5
...b1/ 19...Bxh2 20.Bxc6+ bxc6 21.Qh1 Be5 22.Qxc6+ (=)
...b2/ 19...Be5 20.b5
......b2a/ 20...Nd4 21.Qxa7 (+=)
......b2b/ 20...Nb4 21.Qxa7 (+=)
......b2c/ 20...Ne7 21.Qxa7 (+=)
......b2a/ 20...Nb8 21.Qxa7 (+-)
...b3/ 19...Be7 20.Bxc6+ bxc6 21.Qxa7 (+-)

c/ 18...Be7 19.b5 Ne5 20.b3 (+=)

d/ 18...Nxb4 19.Bxb7 (+=)

e/ 18...Ne5 19.Qa4+ c6 20.b5 (+=)

So it seems the "De Bouver" gambit gives white in all but lines a small but tangible advantage. Talking about a reversal in the Blackmar Diemer theory !
