In this article we are going to summarize some of the most important tactical resources that come into play in those traps that we can raise in the openings of our chess games . Knowing these resources gives us tools that well used will be very useful.
It is an elementary tactical resource in chess. As its name suggests, it consists of creating two threats at the same time. In the openings we will pay close attention to the possible defenseless pieces of the rival . Karpov himself made a historical mistake against GM Christiansen, which led him to lose a piece immediately, as he allowed his opponent to create a double threat. Lets go see it.
Christiansen, Larry Mark (2620) – Karpov, Anatoly (2725)
Hoogovens Wijk aan Zee (2), 01.1993
1.d4 Nf6 2.c4 e6 3.Nf3 b6 4.a3 Aa6 5.Qc2 Ab7 6.Nc3 c5 7.e4 cxd4 8.Nxd4 Nc6 9.Nxc6 Bxc6 10.Bf4 Ch5 11.Be3 Ad6 Black intends to control the box f4, but … 12.Dd1
The white lady attacks the knight and the bishop at the same time. Even a player of the stature of Anatoli Karpov, allowed his opponent this opening trick. The key is in the defenselessness of the pieces. That’s why it’s always good that our pieces are defended against each other.
A somewhat coarser example of the same idea is presented in the following heading:
1.d4 Nf6 2.Ag5 c6 3.e3 Da5 +
White has allowed his opponent to attack both the king and the g5 bishop, which will be imminently captured.
The dunk is a tactical resource that can also be decisive in the opening of our chess games . Nailing a piece means immobilizing it , and in the next two examples we will see how we can apply an opening trick thanks to the fact that we have nailed a pawn, which can not capture the piece that gives mate.
1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nd7 5.De2 Ngf6 6.Nd6 #
The e7 pawn can not capture the horse, since it protects its king from the threat of the white queen of e2. So we found a checkmate very fast, caused by this important tactical issue: the dunk.
In the following example, Black takes advantage of the same idea.
1.d4 Nf6 2.c4 e5 3.dxe5 Ng4 4.Bf4 Nc6 5.Nf3 Bf4 + 6. Bbd2 De7 7.a3 Ngxe5 8.axb4 Nd3 #
The deviation consists of forcing an enemy piece to vacate the square it occupies to stop fulfilling some important function that it fulfills. This tactical resource, like all the previous ones, are very important in the middle game, especially in attacking positions, as we commented in a previous training on the beginning of the annoying piece. But besides being important in the middle game, the deviation can be a decisive tactical resource that gives rise to some trick or trap in the opening of our game of chess . Let’s see examples:
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6 6.Bc4 g6 7.Nxc6 bxc6 8.e5 nxe5 9.Nxf7 +
The black king defends his lady, but now he must capture in f7 … and we already know what will happen.
9 … Rxf7 10.Dxd8
1.d4 f5 2.Ag5 h6 3.Af4 g5 The advance of the black pawns weakens the diagonal h5-e8, something that White can take advantage of later. 4.Ag3 f4 5.e3 h5 6.Ad3 Th6 7.Dxh5 +
The lady deflects the tower of the defense of g6. The deviation is a tactical resource especially useful when our opponent has an overloaded piece, that is, that defends too many things at once (like the tower of h6, which defends both h5 and g6)
7 … Txh5 8.Ag6 #
The attack on the discovery is another tactical resource that we must know. When it is check we talk about “check the discovery”. This check is not produced with the piece that moves, but this, when moving, gives way to the action of another piece, which will be the one that gives the check. Let’s see a well-known application of this idea.
1.e4 e5 2.Nf3 Nf6 3.Nxe5 Nxe4 4.De2 Nf6 5.Nc6 +
White, with this check, force the winning lady, who has been attacked by the horse.
With this tactical resource we force the enemy king to go outside, so that he is no longer protected by his pawns, and is exposed to the attack of our pieces.
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6 5.Nc3 Ag7 6.Ne3 Nf6 7.Bc4 0-0 8.Bb3 Ca5 9.e5 Bb8 10.Bxf7 + Rxf7 If blacks capture with rook 11. Ce6 wins the lady. 11.Ce6 Rxe6
White has forced the black king to leave his refuge. Now mate is inevitable. Note that the horse could not be captured by the d7 pawn, due to the theme of the dunk, since the queen of d1 would capture the queen of d8.
12.Dd5 + Rf5 13.g4 + Rxg4 14.Tg1 + Rh4 15.Ag5 + Rh5 16.Dd1 + Tf3 17.Dxf3 #
1.e4 g6 2.d4 Ag7 3.Nc3 d6 4.Nf3 Nd7 5.Bc4 a6 6.Nxf7 + Rxf7 7.Ng5 + Rf6 [7 … Rf8 8.Ne6 +; 7 … Re8 8.Ce6]
And to finish an example where we see an opening trick where two important tactical issues that we have dealt with are combined: the dunk and the double threat. And it is that with certain frequency the tactical themes come into play in a combined way.
1.e4 g6 2.d4 Ag7 3.Nc3 c5 4.dxc5 Da5 5.Ad2 Dxc5 6.Nd5 d6 7.Bb4 Qc6 8.Bb5 (pinned)
8 … Dxb5 9.Cc7 + (double threat)
