The Curling School
This chapter will provide the new and experienced curler with an outline for strategic decision-making. Each player, team, game situation and ice conditions are different so we'll concentrates on the decision-making process and not on individual shot calling.
Basic Strategy Someone once said that curling is chess on ice. This is true to some degree because, in addition to throwing and making shots, the skip must determine the course of action to be taken during the game, what shots to call and when to call them. This is known as game strategy or "calling the game."
Strategy has two separate components:
1. Overall strategic game approach
2. Shot-by-Shot Tactics (shot calling)
The term "strategy" is often used to describe both of these components, but we want to concentrate on the differences between them.
The term strategy best refers to the overall course of action taken by any team during the game. This "game plan" is determined before the game starts and is based on known variables like your team's general skill level, the opponent's general strengths and weaknesses, general ice conditions, etc. Even the format of the competition can impact the game strategy. Strategy can change, and sometimes should, during a game. For the most part, the game strategy is determined before the game and all shots called during the game are in support of the overall strategy.
Some examples of overall game strategy are:
Once the game strategy has been determined, the skip must support it by thinking about how each end will be played. In each end, the skip then must determine what shots to call and when to call them. Shot calling represents the tactical support of the larger strategy.
There is no such thing as textbook strategy. There are guidelines, however, that apply in many cases.
The first and most important component to strategy is execution. Without proper execution of shots and sweeping, no strategy will be effective. The best strategy is the one that plays to your team's strengths and takes advantage of the opponent's weaknesses. Any type of strategy or tactics is appropriate if it's effective.
"Aggressive" vs. "Conservative" Game Strategy
The term aggressive refers to calling and executing shots that, when executed properly, have the highest potential for forcing the opponent's mistake (or inability to score). Aggressive shots usually include different types of draw shots like "come-arounds," freezes, tap backs, etc. In curling, as in other sports, this strategy has a high degree of risk and a high potential pay-off. For example, a perfect freeze almost eliminates the opponent's ability to remove the rock, increasing the chances to score more than one. On the other hand, poorly executed freeze may leave a rock wide open for a hit and roll, resulting in the opposition counting or scoring two.
A conservative strategy is used by teams who want to keep the game free of clutter. The shots most likely played in a conservative game would be mostly take-outs or shots thrown into the rings without cover. Teams playing a conservative game throw so many takeouts that some people believe the game has become boring to watch. Because of this, the World Curling Federation adopted a rule that would force teams to play more aggressive games. This rule is called the "Free Guard Zone" rule. This rule was adopted for spectators. You won't find many people watching your league games, but the National and World Championships enjoy a sizable crowd, live, on television and on the Internet.
The "Free Guard Zone" Rule
The rule reads like this;
"No rock lying in the free guard zone can be removed from play by the opposition until the first four rocks of the end have come to rest. The free guard zone shall be the area between the hog line and the tee line, excluding the house."
Note: The rule states that; no rock can be removed by the opposition, this means that you can remove your own rock from the free guard zone.
Because rocks thrown into the free guard zone cannot be initially removed, teams are forced to play with one or more rocks in front of the house. This creates a certain degree of excitement with more aggressive shots being played.
All games leading to the world championships use this rule. However, not all leagues or bonspiels use it.
Shot-By-Shot Tactical Guidelines There are many factors that determine what shot to throw. Because of the infinite number of possible options, no strategy plan is absolute. Most of the time, shot calling in any given end is determined based on who has last rock. With last rock advantage, the idea is to score, usually more than one rock. If more than one rock cannot be scored, many teams will decide to blank the end, retain the hammer, and try again next end. Without last rock, the idea is generally to steal one or more or, in some cases, to force your opponent to only one.
Generally, with last rock, try to keep the center of the sheet open. Since you have the last rock, you will need to have access to the center of the house for the last shot (the four foot). By not keeping the center open, you will run the risk of having the center of the house blocked for your last shot. Having last rock is not an advantage if you can't score with it.
Without last rock, most teams try to steal one or more rocks. To do this, try to throw rocks short of the house, preferably in the center of the sheet. With these rocks in place, a rock can be drawn in behind, under cover. This represents the best chance to not only prevent the opponent from scoring but to steal the end.
Other Considerations When Determining Shots Called
End - The strategy in the late ends of a game may differ from the strategy earlier in the game.
Score - The score of the game may determine strategy. A sizable lead will look different than trying to catch up.
Ice - Ice that does not curl much may warrant a different strategy than ice that curls a lot. The same is true with fast ice and slow ice.
Skill - You and your opponent's technical ability should drive many of your strategic and tactical decisions.
Some examples of how the "End" will determine shot calling
Considering your game strategy, you may want to play more conservative shots early in the game. This will allow you and your team to become acclimated to the conditions, allow you to read the ice and to assess the opponent's strengths and weaknesses. This may also keep the game close by not allowing either team to score a big end.
Later in game (the last three ends) is the time to stay steady. Many games are won and lost in the last three ends. Teams must concentrate on a good balance between aggressive shots and good execution. Now is the time to protect your lead or to make a move if you're behind.
Some examples of how the "Score" will determine shot calling
Again, based on your game strategy, the score will help determine the shots called. For example, in a close game (difference of one or two rocks) the shots called should not stray from the game plan.
If your team is down by a considerable margin, the game strategy should change to a more aggressive one. This is the time to call freezes, center or corner guards, close come-arounds, etc. If the opponent puts a rock in the house, you may want to ignore it and put up a corner guard (you can remove the shot rock later). Another approach is the freeze. The best freeze situation is when the opponent's rock is behind the tee line. This is a low risk freeze if you have the hammer because the button is still open for your last draw. Even if the rocks are in front of the tee, try freezing to them. This will make it difficult for the opponent to remove them. The old phrase "live and die by the sword" certainly applies here. Aggressive shots can backfire if not executed properly and you may end up shaking hands earlier than anticipated. Aggressive shots will yield a higher return (more rocks).
If you are leading by a considerable margin, consider changing the strategy to keep things open. This, if executed properly will limit the opponent's ability to get back into the game. This is risky because any dramatic change in strategy must be accompanied by solid execution or it will backfire. A good example is the team trying to keep things clear that cannot make a peel therefore leaving rocks in front of the house without any counters.
The throw-through is an important tactic late in the game with a sizable lead. The theory behind the throw-through is that if there are no rocks in play, there is nothing for the opponent to draw around or freeze to. Usually, teams wait until the last few ends to throw rocks through. The throw-through being executed in the middle ends is a strong statement that you believe the opponent can't catch you. This is embarrassing if they do.
Some examples of how the "Ice" will determine shot calling
This refers to ice conditions. Certain ice conditions favor certain shots. For example, straight ice (less than two feet on a draw) does not favor the come-around. In many cases a come-around attempt on straight ice will result in a rock that is wide open for the opponent to hit and roll. In this case, the promote is a better call. The promote is easier to throw on straight ice because it removes the variable of a large curl. Sweeping is also very effective in keeping a straight rock even straighter.
On the other hand, ice that curls (more than 2 feet on a draw) favors the come around and not the promote.
In some cases, the ice will curl on one side and run straight on the other. If available, always choose the straight side for hits and the curl side for draws.
Another ice condition that drives shot calling is the speed of the ice. Fast ice (23 seconds or higher) will favor the aggressive shots like the freeze or the tap back. Sweeping is usually more effective on faster ice therefore players can be sweep a rock to a more precise location. Slow ice (22 or less) does not favor aggressive shots but favors the conservative approach of heavier hits or hits and rolls.
Remember, ice conditions change during the game. The pebble may be heavy to start then as it begins to breakdown the ice gets faster. If the pebble breaks down too much, the ice may slow down again. This is the best reason to time shots to determine relative change in ice conditions.
Some examples of how the "Skill" will determine shot calling
This refers the skill of you own team as well as the skill of your opponent. Skill is broken up into two categories.
1. The ability to hit the broom on line
2. The ability to throw the proper weight
You should already know the basic skill level of your teammates. Common sense applies here. Don't call delicate draws for someone who can't even hit the house. You are usually better off with a rock in play than with a rock in the garage. On the other hand, heavy hits are not a good idea for someone who can't throw more than draw weight. Just as you avoid these weight-based situations with your own team, try to exploit them from your opponent. Try to force the opponent to a draw and so forth.
When it comes to hitting the broom and line, avoid hits with the person who can't hit the broom. The draw may a better option.
Now is a good time to watch the releases of your opponent. Many curlers (even the advanced players) throw rocks off line during the release. Try to spot patterns with your opponent. If your opponent has the tendency to toss out the out turn, then force that person to throw that turn. Sometimes a partially covered rock is better than a rock fully covered because it tempts your opponent to go after it, perhaps on their weak side.
Free Guard Zone Strategy Guidelines As mentioned earlier, the Free Guard Zone is the area between the tee line and the hog line, excluding the house. See the rules of play for details. No opponent's rock can be removed from play until four rocks have come to rest. Generally, there are three tactical approaches to playing with the Free Guard Zone Rule in place:
1. Be the first team to the four-foot by drawing around a center guard.
2. Begin clearing rocks from play once four rocks have come to rest.
3. Ignore the center guards and draw to the sides
Unlike regular tactical guidelines, deciding when to use the above guidelines depends more on the end and the score than who has last rock.
Early in the game or in a game where the score is close, even with last rock advantage, many teams decide to draw behind a rock in front of the house, after all, your options are limited because you cannot remove the front rock from play. This is an attempt to be "first in" meaning the first team into the four foot. There is risk however, when deciding to play in the house. The opponent uses front rocks to hide behind in order to steal the end.
Put up a corner guard and try to force the opponent to the sides. Eventually, you will have to move the front guard and play aggressively for multiple points.
Option #3 Another option, particularly if you are ahead on the scoreboard is to wait a few shots then begin clearing the front rocks in order to expose the four-foot. Usually, by the time you're allowed to remove rocks, there are multiple rocks in play. Teams that have players, the second in particular, who can throw heavy weight are more likely to be successful with this option. The key to this approach is the heavy weight take out. The weight needs to be heavy enough to move multiple rocks.
Option 4# The last option is used primarily with weaker teams. Try drawing to the sides. This increases the risk factor for the other team to steal. If they truly need to steal, they will ignore the side rocks and concentrate on center guards needed for the steal. If they are not committed to stealing, they will chase you to the sides. Eventually, one team will hit and roll behind the center.
Tactical (shot calling) Options
We'll cover some actual shot calling but will concentrate on the first few rocks of each end. It would be exhausting to think of all the possible shots so we can try the first few.
Without the Hammer.
The aggressive starting shot without the hammer is to place the rock in front of the house, on the center line anywhere from 1/2 in to 2 feet out. Since it cannot be removed from play, it will allow you to build up front guards in order to draw around or promote. Remember, asking your lead to throw this shot is like calling for yourself to hit the button.
A conservative starting shot without the hammer would be a draw to the four-foot. If this is the decision, be sure that the rock is not behind the tee line. Your opponent may take the opportunity to freeze to it, forcing you to throw more difficult shots.
With the Hammer.
Of course, if you have last rock, you will need to wait for the opponent to throw before you throw your first rock. Where the opponent's rock ends up will then determine your course of action.
Let's use the above examples and respond to each.
If the opponent places the rock directly in front of the house about one foot, then the most aggressive response would be to draw behind it. For the most part, the Free Guard Zone game is played inside the four foot and the first team in has a definite advantage. This is a difficult shot, particularly on straight ice. You run the risk of leaving it wide open where your opponent can hit it and roll behind the guard.
Your options are limited here. Another choice would be to draw to the side of the house, ignoring the center guard.
Another would be to split the guard and the shooter onto the rings. This is effective when you're trying to keep things clean because you can remove it with your next rock if it's in the house.
Summary Obviously there are a lot of variables that come into play with game strategy and shot calling. As you see more and more situations, you'll begin develop a sense of what works and what doesn't.
Never criticize anyone's strategy until you have all the information. It is very difficult to understand all strategy calls from behind the glass. What seems to be an obvious strategy blunder may turn out to be a game saver or a brilliant assessment of conditions. It's better to ask, "why did you call that shot" than to assume the call was bad to begin with.
