Then again, you're right, this certainly isn't an opening you would play in blitz or quick games. It requires too much thinking, and is therefore boring compared to others.
lol, it requires too much thinking, and is therefore boring?
too much thinking = boring?
Again, you guys are discussing the VARIATION, not the SYSTEM. This variation might favor Black, and others might favor White. I'm only using the diagram as an example; I didn't intend for it to be analyzed for advantages and disadvantages. The point of this thread is to discuss the Colle as a whole, not just one variation.
There is no "system", there is only a collection of variations. It makes no sense to discuss all of them at once without going into detail on any of them, there would be nothing to discuss.
