QGD Vienna Variation Learning With Master Games
First steps in learning this opening for me is to look at a few master games where ideas that I feel I may come up against are played. I will list a good amount of games and make some notes in my head or on the pgn with a # to denote frequent plans, or piece placement or tactics by white or black. Finally each game will be focused on a moment in the game where a tactic was played to finish off the game or on moves that were interesting to me etc.
At the end is a blitz game I played shortly after looking at these games
