Tactics can quickly decide the games of beginning and intermediate players, so knowing how and when to employ them is crucial if you wish to improve your game. Of course, tactics are not a guaranteed way to win but they can change the material balance in your favor and thus make it easier to win due to having a larger army than your opponent. We looked at pawn and minor piece (Knight and Bishop) forks in the last two articles. Now we’re going to look at major piece (Rook and Queen) forks. There is a difference between pawn, Knight and Bishop forks versus Rook and Queen forks. That difference has to do with the value of the material doing the forking. Pawns, for example, are great at forking because they have the lowest relative value. When a pawn forks two pieces, you automatically end up with a material gain. Knights and Bishops, when forking major pieces, (Rooks and Queens) also lead to a material gain. However, when you’re using a Rook or Queen to fork, you have to be careful because of their high relative value. If you have a Rook forking two minor pieces, and those minor pieces are protected by pawns or other minor pieces, then you’re apt to lose material should you follow through with the fork and capture one of those minor pieces!
We’ll start by looking at Rook forks. Rooks have the ability to move along the ranks and files. Unlike the Bishop who can only control diagonals of one color, the Rook can cover both black and white squares simultaneously. Because a Rook is worth more than a minor piece or pawn, your target pieces when using a Rook to fork should be a piece of higher value, such as The King or Queen and an unprotected piece of lower value, such as a Knight or Bishop. Why not a piece of equal value? Well, a piece of equal value would be another Rook and you can’t fork another Rook because that other Rook would simply capture your Rook! As with all forks, the set up is critical to your success. Take a look at the example below:
This is an extremely simplified example but it demonstrates what I just mentioned above regarding the idea of forking a piece of greater value than the Rook and a piece of lesser value. In our example, the White Rook moves to d6 (1. Rd6+) where it checks the Black King on h6 while also attacking the Bishop on a6. The King moves (1…Kg5) and the Rook captures the Bishop with 2. Rxa6. Nice and easy. However, if Black had a Knight on b8, this fork wouldn’t work because the Knight would protect the Black Bishop and following through with the exchange would leave you trading a five point Rook for a three point Bishop. Forks work when the piece being captured after the other piece has moved isn’t protected. However, what if we substitute A Black Queen for the Black Bishop and the White Rook we’re using to fork King and Queen has a bodyguard? Take a look at the example below:
Here, the Rook moves to the forking square, d6 (1. Rd6+). Since it’s checking the Black King, Black has the choice of moving the King and losing the Queen (and the game) or Capturing the Rook. Black opts to capture with 1…Qxd6. Now we see why the Rook needed a bodyguard. Remember, the Queen moves like both a Rook and Bishop, so forking a Queen with either of these two pieces requires a bodyguard for the forking piece. White plays 2. Bxd6, winning the Queen at the cost of a Rook. The net gain of this tactic is four points of material, trading Rook for Queen. With major piece forks, you often need a bodyguard to assist the forking piece to ensure a gain of material. Thus, the more valuable the piece doing the forking the more carefully you must set up your fork. There is one place where Rooks can can be highly effective against lower valued material, namely the pawns!
Rooks love to reek havoc on the seventh and second ranks, especially when the initial pawn structure (pawns on their starting squares) is somewhat intact. Let’s take a look:
White plays 1. Rd7, forking the Black pawns on c7 and e7. Black can only protect one of those pawns which means White captures the other one free of charge. After 1…Rfe8, White plays 2. Rxc7 winning a pawn. Black blunders with 2…Rac8, attacking the White Rook, thinking White will trade Rooks. However, the White Rooks says “time to take another pawn” and plays 3. Rxb7. Black decides to cover his a7 pawn with 3…Ra8 and the White Rook runs away after creating a three to one Queen-side pawn majority for White with 4. Rb3. This actual tragedy was from a student game in one of my beginner’s classes. White went on to win after being able to promote a Queen-side pawn. Of course, we can thank the Rook for creating the pawn majority!
The above example shows how powerful the Rook can be when it comes to rounding up pawns. However, you must be careful when going on a pawn hunt with one of your Rooks because of the Rook’s value. Hunting pawns with Rooks and Queens can be hazardous to your position’s health. It’s better not to hunt pawns in the first place because you have greater tasks to be tackled, such as winning the game by creating strong positions! Now we’ll look at some Queen forks.
Since the Queen is the most valuable piece aside from the King, you have to be extremely careful when using her, especially when it comes to forks. If you miscalculate your tactical assault, you may become the victim rather than the other way around. When forking with the Queen, it’s best for the beginner to only consider forks that involve the opposition King as one of the forked pieces. Take a look at the example below:
In the above example, Black is threatening to capture the a2 pawn. White could simply move the Queen to b1 or c2 to defend it. However, wouldn’t it be better to win the Rook outright? White can further improve upon his material advantage by employing a fork. Using a Queen fork, White plays 1. Qb3+ which forks the Black King and the annoying Black Rook. After black blocks with 1…Rf7, White plays 2. Qxa2 equalizing the material balance. Of course, if the Black Knight was on b4, this fork wouldn’t work. You should always make sure the pieces you’re planning on capturing after employing the fork aren’t protected.
When using Rooks and Queens for forks, you have to take care because these are your major pieces, having the highest material value. Therefore, you need to make sure they can’t be recaptured after you execute the fork. As I mentioned in the previous two articles, the way to find potential forks is to look for pieces that share a rank, file or diagonal. Rooks fork on the ranks and files. Queens have an advantage in that they can fork on the ranks, files and diagonals. Their disadvantage is that they’re at the top of the relative value scale so if you lose your Queen due to a faulty tactical execution, you’re down a lot of material. Next week we’ll start our examination of pins, a deadly tactic you should know how use. Until then, here’s a great gambit game from the romantic era of the game we all love. Enjoy!
