Dark and Light Square Weaknesses

by Natalia Pogonina for her Tuesday column

Maybe you have heard of light and dark-square strategy. It is associated with exploiting weak squares of a certain color in the opponents camp.

The main reason why squares can become weak is lack of control over them by pawns. If, additionally, the opponents pawns control them, the squares are even weaker. Your own bishop of the required color can be useful in terms of protecting the squares, while the opponents bishop of that color is dangerous since it can easily sneak into your fortress.

How does one take advantage of the weak squares? Here is a plan. The order of the first three points depends on the situation.

1.      Transfer your pieces to the weakened squares.

2.      Fix the opponents pawns to make sure the weaknesses dont disappear. For example, play h5 for White while Blacks pawns are on h6-g7-f6.

3.      Trade pieces that act as guardians of the weak squares. Especially the bishop. Try to keep your own pieces that can burst into the opponents camp via the cracks.

4.      Once your opponents position becomes constrained, its time for the final assault. For example, a breakthrough on one of the flanks. Or an attack aimed at the king.

How does one create a weakness in the opponents position?

Make him move his pawns in an unbeneficial way. Weak players often forget that pawns cant move backwards, and tend to push them every time there is a chance to attack the opponents piece. Therefore, it is not difficult to provoke them. Then take control of the squares using your own pawns. The latter is not a must, but is often a good idea. Remember: to exploit weaknesses, you need pieces that can take advantage of them.

A typical example of creating dark-square weaknesses is losing the g7-bishop in the Dragon. Black usually tries to avoid it at all costs, and prefers to sacrifice an exchange instead.


Vlastimil Hort, at one point ranked #6 in the world, has a great chess experience. For example, against Boris Spassky alone he has played at least 42 offical games!

In my game against Czech legend Vlastimil Hort both sides had weak squares. In Whites case it was the dark squares that became weak after 13.c4. The intrusion squares were d4-c3-b4. One of the plans was to play Bc5 and Nd4, potentially targeting a2. Meanwhile, some of Blacks light squares became weak. White could have forced Black to stick to the h6-g7-f6-e5 setup, and exploit the light squares by Nh4-Qh5-Be4. However, my opponent didnt find that plan and ended up in a passive position. It was hard for him to cover his own weaknesses, so he should have concentrated on creating counter-play in Blacks camp via the light squares.

White didnt do well in the opening; Black got a comfortable position. After e4 the weakness of Whites queenside pawns became obvious. However, by making a few careless moves, I failed to win a very promising endgame. The mini-match was a tie: two draws.

Thanks for that short lesson and game, Natalia. I heard about it via Twitter, as we follow each other there. There is always a new wrinkle in such strategic concepts, and I'm always happy to better my game in any way.
