Online chess textbook: Open (opened) attack. What is a double attack in chess? open attack

In this lesson, we will talk and analyze the chess combination "Open Attack". An open attack is a chess combination in which two pieces participate - the one that moves, and the one thatopens as a result this move. The piece that makes the move can be anything: , pawn, bishop, etc. and the figure which opens the move, the rook, bishop and queen.

Let's look at a couple of examples of open attack combinations. Diagram 1 the white knight moved from the “g4” square to the “e5” square, simultaneously opening a file for the rook, which attacks the opponent's king and . The second example is diagram 2. The white pawn from the “c4” square went to “c5”, opening the move for the white bishop, which in turn attacks the black queen.

What is the tactical application of the chess combination open attack? Most often used to gain a material advantage, attack the opponent's king, gain a positional advantage in the form of a spatial advantage, gain a tempo, and much more.

An example of a successful attack on the king using the “open attack” combination, white checkmates the black king in 3 moves (diagram 3). 1.Nh6+ Kh8 2.Rg8+ Rxg8 3.Nxf7x.

The following example (diagram 4), winning using an open attack combination 1.Nd4xe6! White beat the black bishop (gained a material advantage in the form of a bishop) and at the same time attacked the black queen with his rook, the knight from e6 now threatens f8 and g7.

As can be seen from the examples, the combination of an open attack is widely used to fight for a positional advantage (attacking the king, etc.) and acquiring a material advantage.

With this tactical element, an attack on an enemy piece is carried out as a result of the withdrawal of one's own piece or pawn from the line of attack. As a result, the attack of our linear figure on the enemy object opens. Consider examples.

Played option. White set a trap. If black plays now 7. ... Nxd4?? 8. Nxd4 Qxd4??, then after 9. Bb5+! they will lose the queen. The white bishop opened an attack on the strongest piece with a check. Black is forced to defend against the latter and does not have time to leave the line of attack with his queen.

A comical incident occurred in the next game.

Popil - Marco, Monte Carlo 1902

In this position, black resigned because he thought he was losing the bishop on d4 due to . Meanwhile, they had a spectacular move at their disposal. Cg1!!, combining an open attack on the queen and the threat of mate on h2. White would have to surrender.

In general, a pin to a long-range piece can turn into an open attack at any moment. You should always be alert. Here's another example:

1. d4 d5 2. c4 e6 3. Kc3 Kf6 4. Cg5 Kbd7 5. cd ed

The following situation is also quite typical.

This position came about after 1. d4 d5 2. c4 e6 3. Kc3 Kf6 4. e3 Cb4 5. Cd2 Ke4? Black made a mistake with the last move. Now after 6. Nxe4!(open attack on an elephant) C:d2+ 7. K:d2 White is left with an extra piece. A similar scheme of open attack occurs quite often in the opening and middlegame.

Good day, dear friend!

One of the most common tactics in chess is the double attack. Today we will consider this element of chess tactics in more detail.

Definition

A double attack is a simultaneous attack of a piece on two (sometimes more) enemy pieces.

This tactical tool is very effective. The reason is simple: the opponent can withdraw only one attacked piece in a counter move and only in some cases can protect both at once.

Often one of the two objects of attack is the king, for example:

White checks on e5, simultaneously attacking the rook and taking it on the next move.

We will consider a broader interpretation of the double attack, when two pieces attack one or two pieces - in paragraphs 2 and 3.

1. A piece attacks two opponent pieces

Queen

The queen, which has great mobility and striking power, has the greatest opportunities for inflicting a double attack.

For example:

Black played 1…Ng4, apparently intending to weaken White's kingside. However, after 2.Qd1! it turns out that the queen attacks two pieces at once - the bishop and the knight. One of them is lost.

Horse

A double attack with a horse is usually called.

A typical situation for a knight fork is a fork with a check as a result of a combination:

Whites play 1. Qb3:g8+ Nh8:g8 2.Nd7:f6+ making a fork and calmly take the h5 queen on the next move.

Rook

In practice, quite often there is a situation when the rook breaks into the 7 (2) rank with a double attack. For example:

The rook attacks two pawns - e7 and b7. In chess slang - a gluttonous row.

Elephant

There are also elephant forks in chess. It's just that they are less often talked about, they are so spectacular than horse ones. But no less effective.

1.Rxe8+!! K:e8 2.B:c6+ Ke7 3.B:a4 b2 4.Bc2 and white wins.

In this example, during the course 2.С:с6+ one of the objects of the double attack was the king. This happens quite often - a check and a capture on the next move.

King

The king is strong in the endgame and is able to single-handedly deal with a couple of pieces with the help of a double attack:

Whites play 1.Kd2 and Black loses either a pawn or a knight. In both cases, it's a draw.

Pawn

Double pawn attack - pawn fork. For example:

Whites play 1.d4! and after the departure of the elephant 2.d5!. A fork is a double attack on a knight and a bishop, winning a piece.

2. Two pieces attack an opponent's piece at the same time

The most spectacular example of this type of double attack is the double check. We have dedicated this technique and will not repeat it.

3. Two pieces attack two enemy pieces

The most studied case of such a double attack is the revealed check. Example:

Black's position looks critical: a capture on d7 threatens, followed by checkmate with the rook on b8. However, using the revealed check, they not only successfully defend, but also win!

1...Qd3+!! For a moment, Black gives up the queen, but at the same time attracts the opponent's king under the revealed check.

On the 2.K:d3 should 2...С:c6+ with a simultaneous attack on the king and queen. And after the departure of the king from the check, the black bishop takes the queen.

On the 2.Cre1, rejecting the queen's sacrifice, the queen simply captures the rook on b1 and there is not a trace left of White's attack.

In conclusion, I note that a double attack is a special case of a broader concept - a double strike, and not the same thing. We'll talk about double whammy in another article.

An exercise

Try to solve an example in which the double attack is applied twice, on the 1st and 2nd turn.

White starts and wins
