Breakaway Elimination Strategy
 
Assuming the following:
Ignore the Qualification Matches, these strategies are only for Elimination, where winning means something.
Assume you can pick any alliance within reason. (i.e. a middle-long range bot+ a defender + a herding bot would be a possible team makeup.)

What were the most effective strategies that you have seen played out?

You should probably change the title of the thread too Breakaway Elimination Strategy so it doesn't look like you are going over other strategy threads that have already made.

Re: Breakaway Strategy
 
In our elimination matches, we went with a standard one robot in each zone setup for almost all cases. The alliance of 217, 1551 and 174 who won the championship, would start out one in each zone, then after 217 shot their balls in autonomous, 174 and 217 would switch places, allowing 217 to continue racking up points. The main strategy to emerge as successful was one strong midfielder with good abilities deflecting balls, an efficient scorer, and a defensive robot to assist the midfielder and slow down the opposition. It also helped to have a hanging robot in the alliance to save a close game at the end.
To defeat 217, 1551, and 174, we switched our formation to one offense and two midfielders, allowing us to box out 1551 and deny 217 balls long enough for us to even the score.

An interesting fact, 174 could only push balls, and it was REALLY GOOD AT IT!

I can't personally comment on strategy during elimination, due to the fact that when our alliance played, two of our alliances robots were offline.
What seemed to work well for other teams was to have your fastest robot in the defending zone, because if they could out-maneuver the offending robot, then it was almost impossible to score.

Another thing, hanging was highly situational, based on the amount of balls in the offensive zone.

Scoring more points than the other team.

I disagree. Playing good defense was just as, or more important.

However, in all seriousness I agree that it would serve wise to have a very strong defense in the far zone. A highly maneuverable robot would possess the qualities necessary to deny the opposing alliance any soccer balls to score.

In BAE 1073 and their alliance reigned victorious over 78 and their alliance members through the aid of this tactic. 78 was in their own near zone and attempting to score. However, whenever their vacuum would gain possession of a soccer ball, the defending robot would tap/ram (perspective) them so they lost hold of the game piece. Hence, denying them from successfully scoring much needed points.

So let me get this straight...in the elimination rounds you do not agree with scoring more points than the other alliance? Well, I'll be dammed...that's one heck of a strategy.

In finals, we *tried* to do what everyone else did, that is one defender in far zone, one ball relayer in the middle and a consistent scorer in the near zone, but all three positions were very poorly executed and therefore we took hard losses.

Re: Breakaway Elimination Strategy
 
I can tell you the best strategy is to not have one strategy. The only loss we took was due to us not changing our strategy when dictated by the other alliance's play. The 1511/3157 alliance changed their strategy and we did not adjust. We learned this lesson and had a few "option" strategies based on how they defended us.

The elimination round version of this game is very exciting.

It would be nice if the whole game was like the elims.
Who know? Maybe people would actually enjoy watching qualification matches!:ahh: (WHAT A REVELATION!!!!)
Ah well, there's always the off season.

Haha, many times it was a lighter ram due to our driver trying to get away from 134 (they are REALLY good at defense), but most of the time all three robots (two red one blue) were together as a group making it impossible for balls to be shot. We have a picture that they sent to us with them pushing our robot and we have two wheels on the ground. With two strong drive trains going at it, you will have airborne robots. :D

Our strategy was very plain. One bot in each zone, one defense two offense.

Re: Breakaway Elimination Strategy
 
In reference to alliance structure for the eliminations a good structure seems to be this:

Striker: The Robot that plays in your scoring zone. They should be fast, agile, be able to take defense, and be well driven. They DO NOT have to have a kicker. They just need to be very efficient at getting the balls on the floor of the scoring zone into the goal.

Mid-Fielder: This Robot plays in the middle of the field. Once the match starts, all balls flow out from the mid-field (ball return), and I found that if you can control the midfield you can control the match. This robot should be reasonably fast, have a strong drive base, good ball control, and a decent kicker. It's a bonus if this bot can hang because it's already close to the tower. This robot's kicking and ball handling mechanism should be the best on the alliance IMO, because in some cases scoring from the midfield is very important if your bot in the scoring zone is d-ed up. This robot should also have an autonomous that can get balls out of this zone. Your Mid-Fielder also needs to be able to get out of this zone to score in the scoring zone if need be.

Defensive Bot/Goalie: This robot plays in the opponents home zone. This bot should have a strong drivebase, a powerful kicker (Kicking across both bumps is best) and good ball handling. This machine is responsible for clearing the scoring zone of your opponent and bringing the balls down to their scoring zone. The kicker here doesn't NEED to be super accurate although it is Preferred. This robot also needs an autonomous mode capable of clearing some or all of the balls out of the opponents zone.

This is also based entirely around playing the game in a certain manner. You get as many balls as possible down into your scoring zone using the mid-fielder and "goalie" and then the striker is responsible for cleaning up any missed shots. In some matches this won't work well because of other factors but it's a good base strategy. In many cases the Goalie will need to move up an assist the mid-fielder to keep strong control there.

But this is just my two cents so feel free to disagree.

We will defiantly be attending this year, as we have for the last few. Wasn't it 25 in '09?

It's a little off-topic, but how do the X-Cats manage to attend so many events?
You guys are going to like, 5 regionals!
