Gibbins-Weidenhagen Gambit THE GIBBINS-WEIDENHAGEN GAMBIT by Clyde Nakamura
------------------------------------------------------
In early 1982 I had discovered an amazing gambit in one of my blitz
games with Malcolm Kirkpatrick. I did not know what to name it.
Therefore I used a combined name of another familiar opening, the
Grob's Attack. It was thus named the Queens Pawn Grob. My first
actual game with this opening did not occur til my 2 game match with
Reynolds Takata in 1982.
It was not until I had written a letter to Hugh E. Myers of Myers
Opening's Bulletin, that I had discovered that the Queen's Pawn Grob
had been played much earlier by other players and Masters dating to
the 1930's with Humphrey Bogart's game and to Bronstein's game during
the 1950's. It was also known as the "Bullfrog" and "Weidenhagen
Gambit".
This gambit is very transpositonal in nature. It could easily
transpose into a number of other openings such as a form of the
Budapest Defense, Alekhine's defense, Sicilian Defense and etc.
The opening moves are 1.d4 Nf6 2.g4! The move 2.g4 tends to disrupt
Black's normal development. If black declines the gambit with 2...d5
then 3.g5 can be very troublesome. In some lines white gets play on
the
half open g file with Rg1. If black captures the g pawn with 2...Nxg4
white picks up 2 tempi and a long lasting strategic attack. Like most
other gambits White gets good control of the center, good development
of his pieces and a strong center. Black may have to defend
throughout most of the game.
One of the most interesting ideas that has been tried against the
Gibbins-Weidenhagen Gambit has been Oshima's line (1.d4 Nf6 2.g4
e5.). This is a form of the Budapest Gambit. This was first played
by Oshima against me in 1985. And also in 1986 where Oshima had
analyzed this line extensively but was still busted over the board in
1986. Black gets good development and counterplay for his e5 gambit
pawn.
It has taken me a long time to fully realize that the Gibbins-
Weidenhagen Gambit is not a true Queen's Pawn opening. A good
majority of the games lead to king pawn positions. This is the very
reason that the gambit is so potent.

really tied down. For a long time I had thought that White's game
was unsound. But recent practice games with my Chess Programs has
proven that White has good winning chances.] 7.Bd3 [The other option
was to play the Q to d3 then g3 with other moves such as Bf4 and h4,
if Black decides to castle kingside.] 7...Nf6 8.Nf3 b6 9.Qe2 [9.Qe2
had a twofold function. 1. To prevent Black from playing Ba6
exchanging my attacking Bishop. 2. To attack the weak point at e6.]
9...Nc6 10.c3 Bb7 11.Bf4 [I could have played 11.Qxe6 but Black could
free his game by exchanging Queens. The other interesting move was
11.Ng5 which required exact calcul- ation. I opted instead to
further develop my pieces.] 11...Nh5 12.Bg3 Nxg3 13.hxg3 Qd6 14.Rxh7

free his game. Otherwise the B at f8 could be trapped at f8.]
17.Bxg6 Bg7 18.Ng5? [This was too dangerous. 18.Nbd2 was much safer.
I got too greedy. I saw a chance to win the Black Q at d6 by playing
my N to f7. Also if Black played 18...e5 then I had some tricks with
19.Bf5+ Ke8 20.Qh5+ etc.] 18...Rh8! 19.Nd2 Nxd4! [The first shock! I
did not expect this N sacrifice. 20.Qf1 or 20.Qe3 were not possible

also not possible because of 23...Qxb2+.] 23...Qb4+ 24.Kd1 [At this
point I already accepted the fact that this game would be drawn by
perpetual check.] 4...Qa4+ [Black could have tried for a draw with
perpetual check with 24...Qd4+ but tried for the win instead.]

Recent comment by Clyde; Listed below is the email I recently received from Nico Vandenbroucke
about the Gibbins-Weidenhagen Gambit (1.d4 Nf6 2.g4). Yes, I really
racked my brains on this one.
-----Hello Clyde
I've seen on the internet you're also a fan of this opening ! there's
one line that I find interesting and I would love to share some info
on it.it's your game against Rubsamen,Rogelio Nakamura (2105) -
Rubsamen,Rogelio (2000) 2/19/95 [A45] Dick Dole Memorial Rd4 Gibbins-
Weidenhagen 1.d4 Nf6 2.g4 Nxg4 3.e4 d5 4.Be2 Nf6 5.e5 Nfd7 6.e6 fxe6
and now you quote :[White is 2 pawns down, but Black is really tied
down. For a long time I had thought that White's game was unsound.
But recent practice games with my Chess Programs has proven that
White has good winning chances.] Well I tried it out myself but with
few luck.I play 7.Qd3 and after 7...g6 i'm somewhat stuckWith c5,
Bg7, Nc6,Qb6 black has some serious counterplay , and white doesn't
really have a target to hit at !care to share your analysis.
Regards Nico
-----------
Listed below is my reply to Nico:
I spent the last 2 days reanalyzing the Gibbins-Weidenhagen Gambit
line (1. d4 Nf6 2. g4 Nxg4 3. e4 d5 4. Be2 Nf6 5. e5 Nfd7 6. e6 fxe6
7.Qd3) and have concluded that black is clearly better in almost all
lines. Black has the 2 pawn breaks of c5 and e5 and with Bg7 has
pressure on white's d pawn. White's d pawn is actually weak. There
are a few lines that give white chances but black would have to
blunder or play 2nd or 3rd best moves. Once black gets one of 2 pawn
breaks of c5 or e5, black frees his game and activates his pieces.
Black does not seem to have any weaknesses in his game. It is
difficult for white to mount an attack. Below is the analysis that I
did with Fritz5 on this line.

The counter gambit ! A few years ago I often played this opening with good results.
I remember one particular game that started with
1.d4 Nf6 2.g4 Nxg4 3.e4 and now my opponent played the
totaly shocking and unexpected move 3. .. e5
After 4.Qxg4 exd4 5.Qe2 Nc6 6.a3 d6 7.Nd2 g6
8.Nb3 Bg7 it was Black who had initiative for material.
Finally I was very happy to reach a draw after 23 moves.

Another e-mail from Clyde; The Gibbins-Weidenhagen Gambit – Oshima Defense (1.d4 Nf6 2.g4 e5)
was first played against me in 1985 by Daniel Oshima in a tournament
game. He had prepared this line for my Gibbins-Weidenhagen Gambit. It
is said that he had created a mini-booklet on this line. He had tried
the line 2 times in 2 different tournament games against me, but lost
both games. This is a very interesting counter gambit to the Gibbins-
Weidenhagen Gambit (1.d4 Nf6 2.g4). I have taken another look at this
Oshima line and listed below is my analysis. I have compiled a
database of 17 Oshima Defense games plus analysis lines in a file
called gwoshima.cbv a chessbase compressed file, which I posted in
the files section. What really is the Oshima Defense? I realized
before that it has elements of both the Englund Gambit (1.d4 e5), the
Budapest Defense (1.d4 Nf6 2.c4 e5), the Scandinavian (1.e4 d5) and
other independent lines. A good majority of actual games played have
been with the g pawn chase line (13 of 17 games).

2...e6 variation Another e-mail from Clyde, 26.10.02:
Gibbins-Weidenhagen Gambit Theory (The 2…e6 Variation)
In the Gibbins-Weidenhagen Gambit (1.d4 Nf6 2.g4) there exists an
interesting way for Black to decline the gambit. This is by playing
the move 2…e6 which is like a cross between an Alekhine's Defense
(1.e4 Nf6) and a French Defense (1.e4 e6). After 2.e6 White can chase
the Black N at f6 by playing 3.g5. Black has several possibilites:
3…Nd5 4.c4 or 4.e4 then 4…Nb6. Actually 4.e4 is preferable since with
4.c4 Black has 4…Bb4+ exchanging off some minor pieces. This is like
an Alekhine's Defense where Black is trying to lure White's pawns to
come forward and be over extended. Listed below are 2 sample games
with the 3…Nd5 4.e4 line.

This particular variation (2…e6) of the GWG is new territory and has
not been extensively explored. Over ten years ago someone played this
variation against me in a blitz game and gave me a very difficult
game before resigning to my GWG. Unfortunately I do not have that
game score.

more 2...e6 I had a strange thought. After 1.d4 Nf6 2.g4 e6 White can play an
Omega (1.d4 Nf6 2.e4) type of Gambit with the move 3.e4 gambiting the
e pawn. The g pawn is now guarded. After 3...Nxe4 4.Nc3 Nxc3 5.bxc3
White has that familiar Omega Gambit pawn structure with pawns at
d4, c3 & c2 and with the e pawn missing. The only difference is that
White has a pawn at g4. I am not sure if this new gambit will lead
to a good game for White.
