This is an idea that was proposed to me by Richard Patterson, that I now swear by. I always use this strategy in my solving, and have even used it in official competitions. My fastest official competition solve using my opposite color is 12.87 seconds achieved at the Rubik's World Championships in 2005. Basically all opposite color solving means is that you solve either your regular cross/2x2x2 color or also its opposite.

The below function is exactly why you want to use opposite color solving.

Notice that using two faces

For example, I have a roughly 25% chance of doing an extended cross if I restrict myself to using only one face. Plug this as 0.25=x into the formula and you get F(x) = 7/16 = 0.4375. This means that if I solve extended cross with a 1/4 frequency, then by choosing to solve the opposite face too I now have a 7/16 = 43.75% chance of seeing an extended cross on either my regular color or its opposite.

The hardest thing about opposite color solving is that the colors on F,R,B,L will be seemingly in the "wrong" order. This can be confusing at first, but over time you get used to it. I would not let this initial difficulty deter you though, as your odds of getting even just a good cross will increase by the graph shown above. Say you have a 10% chance of getting a really good, super fast cross on your solve based on your solving style/method/etc.. Well if you choose to also solve your opposite color you now have a 19% chance of getting a super fast cross. And you did this

The purpose of this page is to convince you that solving just the extended cross is not enough. Call this advanced extended cross solving if you want, but I think it should be absolutely required to solve opposite color as well, if you plan on solving with extended cross. As a combination this strategy is so powerful, and I see no reason to only use one part of it and neglect the other part. I now advocate using both strategies together, as it really can aid in your solving times.
