What are common strategies for beating the robot in Race For The Galaxy?

  To beat the robot you need to understand how it works and know how to minimize the chances of indirectly helping it. Knowing that sometimes it "copies" your actions, you need to think twice before selecting Consume x 2 if the robot's economy size is 5 (i.e. it would score 10VP if it also does Consume x 2). The robot's main ways of scoring are the 6-cost development tiles and the victory points. I find that usually it doesn't score much from worlds or normal developments. The 6-cost dev tiles (as opposed to dev cards) are a mechanism to adjust the difficulty level. The robot most of the time will be able to play all of its 6-cost dev tiles, unless you are really really quick in ending the game. So when you decide to play with 1 6VP tile (easy), 2 6VP tiles (medium) or 3 9VP tiles (hard), you are more or less already deciding that the robot will at least have 6VP / 12VP / 27VP.
  
  You need to watch the robot's economy size closely. It's kind of a countdown timer. The robot's economy will grow, sometimes quickly sometimes not, and the bigger it grows, the more dangerous it will be. You cannot allow it to do Consume too many times, especially when its economy size is big. It can earn lots of VPs this way, and also end the game very quickly by exhausting the VPs.
