Dou you all remember some posts ago I would try move 4. c4 in a game with the Exchange Variation? And if Black would get dangerous with moves along the d-file? Well, I played a game and indeed bungeled up, with a Black Queen getting out to d5. Eventhough I still think any early outings by the black queen should not be a problem; apparantly the were nonetheless mine
Look at the following game. I gave some comments, but if others have any suggestions and their own comments, please add these!
there is one line you should consider vs a super early d5. 6.e3 nc6 7.cxd5 nxe5 8.qa4+ c6 9. qxb4
as for early nc6 before d5, here is an improvement over your line. i personally dont like dxc3 at all.
Would you all be interested if I made some videos on Sokolsky opening theory?
They would be similar to the ones I've made on the French and Reti where I introduce the theory before jumping into some model games. I can't promise a full series (as there are some lines with very few games or where FM Hansen's novelties have not yet been tried).
