Anyone play 4.Qc2 or 4.Qb3 against the slav?

I am trying to prepare for an opponent who plays this line (I play the slav as black) and is roughly 2150 FIDE. Would anyone able to play some blitz games against me or discuss the opening? Thanks!

Or play 4 Nbd2, also a safe protection of the c-pawn. Maybe you can trick your opponent with de.lichess.org/nGHu9VQs

Sry, you have the black pieces. Don't get tricked! ;)

thanks for the nice trick :)
