It's a relatively frequent strategy in 2v2 matches in StarCraft II for one player to immediately leave the game, allowing his ally to have a very strong economy to deal with his two opponents. Of course, this still takes a lot of micromanagement for the player remaining in the game to build up his own base and his ally's economy at the same time.
It is particularly powerful with a Terran/Protoss team, because Terran can mine so quickly with MULEs and the Protoss player, given extra money, can produce such a powerful army.
Is it possible to employ this strategy without the Terran player leaving the game, however? Is there any limitation to the timing and/or amount of resources that can be shared between players? Can the Terran player start feeding the Protoss player extra resources immediately?
