Basic tactics in chess part 4- Discovered Check

Till now we saw tactics with all sorts of frontal attacks. Pins, Forks, Skweres, Double attacks. All of them were done with the attacker having one piece which attacks the target. Today we will see how to do surprise attacks in chess. Discovered check and Discovered attack

Frontal attacks are easy to expect and judge and also easy to prevent. Hidden or surprise attacks need to be predicted and for this, it is really a task for the defender to ensure that he is not on the receiving end of something nasty! In wars, a surprise attack was a common tactic that was done to dismantle opponents harmony of forces.

So, similarly, when you are playing a game of chess, the position is totally under control, and suddenly there comes a check which leads to either heavy material loss or direct checkmate. Discovered check and discovered attack is a lethal weapon in chess tactics. One must have a good practice of the same.

Discovered check and discovered attack is a theme where a long-range piece (Queen, Rook, Bishop) is behind a piece that cannot directly give a check or attack the targeted piece. For example, if the opponent’s King is on e8, And we want to give a discovered check from the same e-file, then the piece between the opponent’s and our Queen/Rook needs to be a bishop or a Knight or sometimes a pawn.

Positions –

Today we see a few positions on the discovered check as well as the discovered attack which will be followed by a popular opening trap! So let’s get started with the same –

Basic position of discovered check

In the above position, white moves his bishop and gives a check.

White to play

The above position arises from petroff defence which is a popular opening now a days. Also the position comes after a blunder from black side.

Black to play

Black can win material with a check. So check wisely!

White to play

Here white has a clear way to win Queen with a discovered check.

Again, white to play. This position pans out from French Defense advance variation. Grabbing material early on in the game is bad and here is a good example of it.

So lets see on how do we reach both positions where discovered check leads to decisive advantage.

Petroff Defence Trap-

I remember when I was playing chess in my club, Someone did beat me with this trap. I felt very bad but soon I got a few victories with the same moves!

1.e4-e5  2.Nf3-Nf6 (This is called the petroff defence while Nc6 protecting e5 pawn is also a natural reply.) 3.Nxe5-Nxe4?!(Already a dubious move. The correct reply is 3. …-d6 4. Nf3-Nxe4) 4.Qe2!(Setting a trap) Nf6??(falling in the trap!) 5.Nd6++(Discovered check as well as discovered attack on the d8 Queen) Be7 6.Nxd8 (Queen lost.)

French Defence Trap-

I have played french defence for most of my life and this opening trap is quite common. Beginners often fall for it.

1.e4-e6 2.d4-d5 3.e5(Here white has a lot of options like Nc3,Nd2,Bd3,exd5 etc)-c5 4.c3-Nc6 5.Nf3-Qb6 6.Bd3(A sneeky trap which is misjudged as a pawn blunder.)-cxd4 7.cxd4-Nxd4? 8.Nxd4-Qxd4?? 9.Bb5+!(Discovered attack on the Queen on d4!)-Kd8 10.Qxd4.(and black loses his queen and also the game soon.) Now lets see, how black could have correctly reacted. 7.cxd4-Bd7! and this move will stop Bb5+ in future and now black is ready to grab the pawn on d4. This is a theoretical position in french defence advance variation.

So you can try both the traps, They are quite easy to miss. I would love to hear from all of you regarding your opinions on discovered check themes.
