"my question is what should we do off break? do we lane or run?" -
In 3 man play, I recommend shooting your lane always. Whether you are running, walking, or just standing. You want to have balls in the air at all times of the game or as much as you possibly can. Whether you run, walk, or stand depends on variables...
- What is the field setup like?
Is the middle clustered?
Is there a large X?
Is there a snake bunker that you can cut off?
Is there a "God" bunker that you need to cut off or take yourself off the break?
How aggressive is the other team on the break?
Does the other team have a star player that needs to die on the break?
You want to run (and gun) to a key bunker that needs to be taken right off the break.
When you need that key kill or containment on the break, it is better to just walk (or stand) and lane. Accuracy is the key in this type of breakout. Once your opponents get to their initial bunkers, then you want to get to your bunkers.
"i have seen alot of teams win and they just stay home back left and back right." -
This is how inexperienced teams play. The Alamo method sucks. Don't do it. Use your aggressiveness and teamwork to win the game.
"my next question is when to move?" -
Always move, take what your opponents give you. If you snap out and your opponent ducks into their bunker, stay on them and make your bump. Paintball is a game of angles. Constantly moving will refresh your angles and causes your opponents to play on their heels in reaction to you. This is when that player is basically your *****. As long as you are shooting your gun to suppress your opponent, you can almost do anything on the field (within reason). A basic rule that you should use till you gain more experience is this, "If no one is shooting at you, move."
"i have ran up the field lots of times and found myself locked down at like a 40 tumbstone. What should i be looking for when choosing my spot to bunk up to?" -
If you ever are in a spot that more than one gun is flailing away at you then that is good. You need to communicate this to your teammates as the both of them only need to worry about one gun (or maybe none) and your teammates could do damage. If you get pinned by multiple guns, your job at this point is to lock off a key zone to your immediate right or immediate left and communicate as much as possible to your teammates. You will do your team a diservice by getting shot. Once your opponents react to your teammates and stop shooting at you, be prepared to do some damage of your own.
Hope these tips helped you out.
