A Gambit in the Dutch

by lefthandeddragon, posted in Dutch, gambit, Opening, Uncategorized

The opening 1…f5 can be played against 1.d4, where it is known as the Dutch Defence. Against 1.c4, it is known as the Anglo Dutch. Against 1.Nf3, it is known as the Reti Dutch. And against 1.e4, it is known as bad move.

 

Nevertheless, the move 1…f5 leads to many tactical tangles with Black having a fair chance at emerging victorious.

The sequence 1.d4 f5 is the most common way for Black to play the Dutch. It is this approach we will look at now.

 

White has several ways to reply to Black’s aggressive move. He can play 2.Nc3, 2.Nf3, 2.Bg5 (stronger than one might suppose), 2.g3 (a safe, positional approach), and 3.c4 (a classical reply).

 

But he also has a gambit he can attempt; the Staunton (1.d4 f5 2.e4!?).

 

Black almost has to take the pawn. Otherwise White has a greater control of the center and declining the pawn can also easily lead to bad positions from the transposition of other openings.

So, Black usually takes the pawn. White can respond a number of ways. One good try is 4.Bg5!?

White also has 4.f3, paralleling the Blackmar-Diemer Gambit (BDG).

 
It is usually not in Black’s interest to immediately take the pawn, as these games illustrate.

Instead, Black can try moves such as 4…Nc6 or 4..d5. While these moves are not a panacea, they do offer Black better chances than simply taking the f3-pawn and be defending the rest of the game.

I played in a Women’s Team Championship.

by lefthandeddragon, posted in championship, Dutch, Humor, Uncategorized, women

Just in case you couldn’t figure it out, I’m a male.

  

So how did I play in Women’s Team Championship? This is the story.

 

Back in 1989, the Southern California Chess Federation had a very active women’s group with their own league and some very good players. It was this year they had a  Women’s Team Championship.

  

But let me step back for a moment. It was in 1988 that I started to play correspondence chess. I only mention this because my opponent I was due to play was also a correspondence player. And being a fairly strong one at that (she was a Master in correspondence).

 

 

Back to the story.

 

 

I had several female friends that were playing in this match, so I decided to drive down and watch (and hopefully get a chance to cheer).

 

 

It soon became apparent to all the players that one of the participants had car trouble and couldn’t make to the event. How she made the phone call, I don’t know – this was in the days before cell phones. But news like  this travels fast and soon they were looking for another player.

 

 

After half-heartily looking for another female player (as most of them were already playing in the event), they decided to ask me. I think it was due because of my rating, and the fact that most of the other players personally knew me.  The two games I and my opponent were to play were to be rated but not counting towards the overall score in the match.

 

 

I agreed and my opponent, Dr. Christine Rosenfield drew White for the first game.

 

Now I knew she was a good correspondence player – but I didn’t know how good and I didn’t know a thing about her 1.d4 openings. Remember this is before cell phones, the Internet, and chess web sites.  I played loosely with my response, a little loosely as it turned out. She had a strong d-pawn in the middlegame and I couldn’t do anything about it. I lost the game. Badly.

 

 

So we take a lunch break. And we both chatted about game, as well as other games that were played in the first round.

 

 

After the meal and the chatting, we started the second game. I didn’t know anything about Christine’s openings, and I felt sure she didn’t know too much about mine either. I began with my favorite opening and played 1.e4.

 

 Now I was in my territory.  I have always been good with tactics and this game featured  open lines, control of queenside and two pawns that couldn’t be stopped. 

 

So we tied with one victory each. A good way to start off any friendship. But, if I remember correctly, she had to move to another state the very next year.

 

 I enjoyed my experience and my games. I enjoyed my company and I got another view into chess. Dr. Christine Rosenfield has my respect. I’ve studied her correspondence games and learned how sometimes it is necessary grind away to victory. And how to use a very strong d-pawn.

 

Oh, that was an experience!

Here are some correspondence games from the Christine Rosenfield.

I should also mention that correspondence players are noted, and notorious, for slowly eroding away any advantage that their opponent might have.) 4.Nc3 g6 5.e4 Bg7 6.Bd3 O-O 7.Nf3 Bg4 8.h3 Bxf3 9.Qxf3 Nbd7 (The game is about even here.) 10.O-O Ne5 11.Qe2 e6 12.Bc2

The Dutch is an aggressive response to 1.d4. It is also extremely risky.

Here are some miniatures showing how White (and Black!) can win quickly.
