You can clearly see the purpose of this opening, sacrificing a pawn to get a development advantage and controlling the open f and e file. White will have many chances to attack here, and there are many ways to play this gambit.

As we mentioned before, if black takes the pawn (4…exf3) white has two options to continue:

  • Nxf3
  • Qxf3

We will have a look at both moves now:

In the case of simply taking the pawn with Nxf3 White will try to attack the kingside using the open files. The idea will be to put pressure along those diagonals and put pressure using also the space advantage we have.

The game may continue like this in this case:

And we have an ok position, where both sides have chances. But white is probably better in this position.

The second option is the move Qxf3 which is an even sharper option. Even though many people don’t like this position for the simple fact that it gives up another pawn, is interesting.

Many people simply try not to choose this line because the computer hates it. However, in practice, it has worked really well for white, which means at least that black has a hard time defending this.

Plans and ideas of the Blackmar Diemer Gambit


The ideas of the Blackmar Diemer gambit are to attack, simply attack, and you have to follow the attack principles. White will have to seize its space and development advantage, the main idea being that you can checkmate fast.

Or at least, get a position where you have compensation for your pawn. It’s important to know that you can choose to play an opposite castle position or you can castle short. Many people using this opening choose to castle long, which gives more possibilities to attack with the kingside pawns.

But there are also good ideas for black for a quick a6-b5-b4 that you need to look out for. The important principle of not showing your intentions too early in the game enter here.

Focus on developing your pieces first, and try to delay the castle as long as you can, this way you don’t leave the opponent with a clear idea of where to attack.

Honestly, the line with Qf3 is not too recommended, of course, it has possibilities and you can have a decent position out of that. But you shouldn’t try it in so loose time controls, it is something that must be done to surprise your opponent in a blitz game.
