The Ruy Lopez is known as one of the longest-living openings in the history of chess. Players from all generations have played the Ruy Lopez and it is known to be incredibly solid and very difficult to defeat. One line that can arise from this opening is the “exchange variation”. This variation is sometimes used by lower-rated players who want to create doubled pawns for their opponent as quickly as possible.
The variation starts with the moves 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.d4 exd4 6.Qxd4 Qxd4 7.Nxd4. From the very start of the game White has given up his light-square bishop for Black’s knight and doubled Black’s pawns in the process. This creates an interesting pawn structure dynamic between White and Black that will be discussed in this article.
I learned a lot about pawn structure by watching the “Middlegame Pawn Structures” DVD by GM Ivan Sokolov and would highly recommend it if you want to learn more about the topic!
The position to the right shows the basic Ruy Lopez Exchange Variation pawn structure. White already has better control of the center and has stuck Black with doubled pawns. These doubled pawns can either be a weakness or a strength, depending on how Black uses them and how White fights against them.
In a late endgame with many of the pieces traded off, this doubled pawn will be a big problem for Black because his pawn majority on the queenside (4 vs. 3) is nullified. On the other hand, White’s pawn majority on the kingside will be able to be converted into a passed pawn.
With pieces on the board, however, this doubled pawn is less of a liability. Aside from the pawn majority problem for Black, he does have an extra half-open file available that White does not have. Both sides have the open d-file to use but only Black has the half-open e-file leading towards the e4 pawn that could be a potential target.
Black can also fight against White’s center pawn with an eventual f5 pawn push. If White’s e-pawn disappears, then the position will open up more and Black’s two bishops will prosper. Black can also begin to push his c-pawns to c5 and c6 in order to control more space. Factoring in the pieces, White’s best plan is to keep up his control of the center, advance his pawn majority on the kingside and try to trade pieces so that he can be closer to a king and pawn endgame that is winning for him. Black on the other hand should try to open up the position as much as possible so that his bishops will be better, try to trade off the doubled pawn if possible, fight against White’s center and avoid trading pieces.
With all of these ideas contained in this seemingly simple position, both White and Black have a lot of available options. Despite having no queens on the board, this pawn structure is still rich in complexity and very important to understand if you want to play the game optimally.
