The Semi-Slav and Slav Defenses
Today marks the start of a new project: assembling a 1.d4 repertoire by mining MCO. For now I have only one other teammate for the project, chessicstudent, who will be working on the King's Indian Defense. If you're interested in joining the project, please check out the defenses listed here and comment what you would like to work on. If you're interested in another opening altogether, feel free to get in contact and we'll see what we can work out.
Below you'll find in puzzle-format (right now they're invisible, give it a week) all of the MCO variations for the Semi-Slav and Slav Defenses. For the sake of being thorough every MCO line is included. Don't be overwhelmed. By no means should all of these variations be memorized, nor do I plan to do so. I've created this as a document for all 1.d4 players looking to develop a full repertoire.
