#1 Diamond 2v2 Strategy (T,Z)

This is a non-standard build you and a friend can execute to easily get to a top diamond rank in 2v2. It focuses on early aggression (some call cheese), communication, and unit composition effectively working together.

Terran
As Terran, you will be doing a proxy 9-Rax Reaper rush.
Set the waypoint of your first SCV to right outside the enemy base in a spot that won't be scouted.
As the SCV is moving over there, build 2 more SCV's, giving you a total of 9 population.
Once you have 150 minerals, build a Barracks with that close SCV.
As soon as you've built up 75 minerals, build a Refinery.
Build two more SCV's, so your population is now 11/11.
*Make sure you have 3 SCV's harvesting gas when refinery finishes*
To keep harvesting/mining efficiency highest, build a supply depot with your proxy SCV as soon as the barracks is finished.
After the depot, add a tech-lab to your barracks (these should be almost simultaneous).
Begin making the first reaper, an SCV if you wish, and move your proxy SCV into the opponents base you are close to.
Try to sneak a bunker in, most will pull a lot of workers off the line, which is good. If they don't, and you get the bunker up, it is basically GG right there.
If the bunker fails, that's ok. Go for the mineral line with your bunkers, micro intensively.
Once you have your 2nd reaper going, the next 50 gas can be used on speed upgrade for them. This is important, don't forget it.
Keep the pressure on, if you can't break the first guy, move to the other guy's base.
DO NOT ENGANGE: STALKERS, MARAUDERS, OR ROACHES.
Leave these guys for your teammate. Help your opponent if you can, as in the video.

While all this is happening, don't forget to build up your main. Upgrade your OC, throw down more barrackes, it doesn't really matter what you do as long as you spend your money and can respond to what the opponent seems to be trying to do.

Zerg
Very simple strategy for the Zerg player.
Move overlord to enemy for sight.
-10 spawning pool
-10 extractor (build replacement drones!)(put 3 in when finished)
-10 overlord
NO QUEEN
-Make nothing but zerglings.
-At 100gas (~3min mark), research speedling upgrade (metabolic boost)
-Pull the three on gas, put them on minerals.

As the game progresses, it may not be a bad idea to drone and tech up to roaches, most games this is completely unnecessary though.

The most important and difficult thing for the zerg is to KNOW YOUR JOB!!!
Let the reapers do their damage, don't throw away zerglings on zealots or wall attacks. Your job is to protect the reapers from stalkers, marauders, and roaches, which you will easily be able to do simply because of the numbers difference that early in the game.
You must also chase and kill retreating units, metabolic boost helps this incredibly. You need to communicate with your partner where the enemy is so the terran's reapers don't get sniped, and so, when they decide to attack, your zerglings are in front taking the damage and going after the tier 1.5 stuff, while the reapers melt away the tier 1 stuff.
