The Tarrasch Defense has been under a bit of a cloud since this line came into fruition:
At this point, I cannot recall if White is supposed to go to a4 or e4, I think a4 makes more sense, but I do not play this defense and I am not a d4 player any more.
Problem is after 7...Bxc5 8.Nxc5 Qa5+ and 9...Qxc5, the Bishop pair is a problem for Black.
I played the queens gambit opening with a friend today, and they played this defense, I got kinda thrown off, what is this best way for me to counter this?
