Queens Gambit Declined

White can try plenty ideas in that final position, usually after kingside castling because there is no reason why black can't generate as much play against king in opposite castled position as white can king. There are ideas like minorty attack a3, b4-b5, and central play re1, f3, e4 eventually. Black can counter these ideas. Look at games by Short at Candidate Match level against Timman, Geland? for example.

Note that successful for GM's doesn't mean successful for us.

Yeah, except this is a main line Slav rather than a QGD (you don't even have ...e6 in)
...nice collection of super-duper games you have
Nimzo-Indian Defence is my favourite way to play it.
