The Black Diemar Gambit (accepted)
I want to go over a very aggressive opening from white, that isn't played very much at master level, but sub 2000, it works well for a couple of reasons. First, it gets people out of memorized lines fast, so it isn't like the sicilian where people can literally memorize the "best play" first 50-60 moves. Second, you are getting all of your minor pieces out before your opponent develops more than two pieces usually.
So a bit about the Blackmar: It is a true gambit. You dont usually get the gambit pawn (or pawns) back in the next two to three moves. You have to play aggressive to really use this line, if you prefer slow positional play, this is not for you. And again, not everything here is memorized, you will have to be creative in your attacks as this really is a deadly line, if you can find great lines.
So lets take a look at how the Blackmar starts:
Okay, so as you see, no matter how white takes back, We are down at least one pawn and our opponent is thinking we are idiots, just throwing pieces at them. Now there are two continuations. Nxf3 or Qxf3 (also known as the Ryder Gambit).
We will look at Nxf3 a bit first.
Now, out of all my games with the Blackmar, I can only find 3 where I castled king side. If instead of developing their bishop, Black develops the knight, and it looks like a slightly messed up 4 knights, then we will castle king side.
Now, If instead, you are like me, and you want to play even more aggressive, then I suggest Qxf3 early on. Which will give up yet another pawn, and leads to even more lethal lines, and an awesome trap as well.
And from here, Black needs to be really careful. Black is looking at the board, and sees a tactical nightmare for white. The queen and the rook are on the same line, the bishop could hit both, and is protected by the knight right? This is where the Halosar trap comes into play.
So black cant take the Queen or white goes 1-0, which I have seen a good number of times.
There are many other lines that this opening can get into. And no victory is guaranteed. Black, only needs to castle, trade pieces, and go into an endgame up the material, and this game goes much different for white. One way of doing this is like I mentioned above is best play of an early trade of queens. Let's take a look.
So, as you can see, this isnt a line where white just recaptures the material quick fast and in a hurry. But instead takes the tempos, and control over the center, owns the open d file, all to get to a point of being able to attack much faster. White wants to take this lead in development and try to keep black from castling, play Nb5 or Nd5 to threaten mate or fork the rook, and white has real fighting chances.
Anyways, I hope this gives you a bit to think about. If you want to see games I have played with this opening, hit me up and I can add to this or just put them in the comments. If you have questions about the opening, feel free to comment or message me.
