Dekker Gambit games...via Google Docs

Mention "Microsoft" in polite company and, like Pavlovian dogs, it'll bring out the usual litany of complaints about rubbish software, greed and so on. As a developer, I actually regard Microsoft highly, they look after developers very well.

Curiously, this same response is not evoked by Google. Perhaps that's because Google has offered its services for free for so long. Perhaps it is because Google has not been around long enough to earn standard disparaging remarks. Who knows.

Today, Bronwen showed me Google Docs and its pretty awesome. I've taken the opportunity to publish, in PGN format, a list of the Dekker Gambit games played so far. This list will be kept up-to-date as new games are played, including games played by other people.

Please review the list and if you are inspired to play the gambit (its quite sound and a very fair judge of chess skill of both players, apart from being a lot of fun) then please drop me an email to send me your thoughts, game scores or questions.

Here's the link:

Dekker Gambit


Since 1998, I have been playing a certain variation against the Najdorf that very pleased with. As discussed later, while I am not the first person to play this opening, the idea was original to me and nobody has attempted to name the opening before. This is the story of how I came up with the variation.

One day I was playing blitz with a chess friend of mine, Hans Steyn. At that time, Hans was trying out the Schevenengin (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e6) to which I was invariably playing the Keres attack (6.g4) which results in a superb attacking game for both players. Well, during one game, Hans threw in 5...a6 (the Najdorf) instead of the expected 5...e6. On autopilot, I continued with 6.g4 and we both found, to our mutual surprise, what wonderful positions arise from this move.

Over the next few weeks, I experimented with the move in a few blitz games as well as looking at the positions at home. Feeling confident that this was a playable move, well suited to my style, I essayed the move in a serious game for the first time on 05 July 1998. The tournament was the South African Open (held in Pretoria that year) and my opponent was Robert Mills, a former junior star in South Africa. After a very interesting struggle, Robert did win the game. Taking on the lessons from that game, I again played it against Robert in early 1999. Having improved the placement of the pieces (advancing the "theory"), I won this game and subsequently got it published in the November 1998 CHESS Monthly magazine.

The Dekker Gambit moves are: 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.g4!? White should expect 6...Bxg4 7.f3 when Black can choose between 7...Bd7 and 7...Bh5. I consider the latter to be the better move.

Initially, the gambit looks crazy, but White achieves some important counterplay:
a) The g-file is opened for a rook on g1;
b) The f3 pawn supports the centre e4 pawn and frees the Nc3 from its defence;
c) White has easy development choices, targeting the kingside or queenside (eg. the weakness on b6);
d) Psycology: Black is immediately out-of-book and besides which must withstand an easy-to-play attack.

It is true, it must be stressed, that the Dekker Gambit is probably not 100% sound. This is not in the sense that Black is winning, but that with best play Black reaches an endgame with slightly better chances and a draw will probably be the result. Against committed and accurate play by White, however, Black must withstand sustained pressure where White enjoys enormous fluidity. Since 1998, I have played the Dekker Gambit in well over a hundred games, winning the vast majority of them.

Interesting post-scripts: In 2005 I went to a book signing of "My Great Predecessors" by Gary Kasparov in London. While signing my book, I had the opportunity, very briefly, to discuss the opening with one of the greatest Najdorf exponents ever. "What do you think of 6.g4!? in the Najdorf, Mr Kasparov?" I asked. "Ahh I've seen this" Kasparov answered to my surprise, "but it isn't so good". He then proceeded to rattle out around a 12 move variation which I gathered involved ...Bd7 and ...g6 and ...Bg7. Who am I to argue with the great one? But...I'll still play the DG on very possible occasion. My heart lights up, I cannot help smiling and the lust for battle is aroused when I see 5...a6!

2nd interesting note: I have subsequently found that I am *not* the first to play 6.g4, though I do believe I am the first to claim naming rights for the opening. I certainly came up with the opening idea myself. The other games can be found on the on-line database at www.chessbase.com and are:
Padevsky, Nikola - Petrosian, Tigran (0-1) 1965
Ciocaltea, Victor - Vaisman, Volodia (1-0) 1967
Navas, Miguel Angel - Mansilla, Raul Oscar (0-1) 1998
Peters, Charles William - McGary, Fred (0-1) 1999
Fargnoli, Rodrigo Veloso - Gonzalez, Bolivar Ribe (0-1) 2002
Wieczorek, Oskar - Mertens, Fridolin (1-0) 2002
The quality of the above games is generally quite poor, though the Fargnoli game is to be recommended.

Players interested in receiving a database of good quality DG games, are free to contact me at abdekker@fsmail.net and follow the anti-spam instructions in the replying email. I'd be most interested in any comments, players who try the opening, criticisms or attempted refutations.

My first blog

Jumping on the bandwagon. I've decided to create a blog website. Bronwen has already done so at www.brondekkerhome.blogspot.com. When she'd done that, I searched for my own name to discover a young Dutch boy with the same name as me (yes, even the same spelling!) had beaten me to it.

Alain and Bronwen:
Grew up in KwaZulu-Natal going to Hillcrest High and Northwood Girls High. University at Unversity of Natal-Durban (now the University of KwaZulu-Natal) . Both did Chemistry, though our majors were Physics and Biology respectively. Married in 1998 and Bronwen came over to the UK in 2000 for PhD

Alain is the creator of the Dekker Gambit in Chess (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd5 Nf6 5.Nc3 a6 6.g4!?) more of which will appear on this blog later. I am also interested in many other games such as Xiangqi, Go and pacru (www.pacru.com).

If you hit on this blog, why not comment on it, or drop me a line at abdekker AT fsmail.net.
