mulde: IM Krzysztof Pytel is called the founder of -Qd6 in the Scandinavian : 1.e4 d5 2.exd5 Qxd5 3.Nc3 Qd6 which is frequently played by GM Sergej Tiviakov (2601) and GM Alexander Rakhmanov (2654). It should be said, Bożena Pytel (Krzysztof's wife, not sister) seemed to be the first one who gave -Qd6 a try in the following:[Event "POL-chT Augustow"]

If you can have a Scandy with Black and O-O-O, you might have a real fun-game with all risks. It develops quickly, and it might be a good opening for those who have not too much time for theory. But as Tiviakov shows us: It's a grandmaster-opening.
