The difference between Greens and Greats/Unicums

pizzastorm: You don't need to know all the ins and outs of a map to be successful on it. You just have to make the best out of what is available to you.

For instance, I have done well on the new maps that have come out since I can recognize how I should play the areas that I wind up in. There are so many maps that somewhere in your past experience you will have run into a similar area, if you can apply this past experience then you will be fine.
