3.Nc3 dxe4 4.Nxe4 Nf6
If you don't want to play the Tartakower play the alien gambit, I said this in my original post. In order to play the panov per your move order you have to play 3. exd5, which is an exchange of center pawns, so I don't know why you are mentioning other Panov lines. The exchange of the center pawns is more passive then advancing which is the more confrontational line. That is what I am trying to say, I don't know what else to tell you. If you don't want to play passive don't exchange the center pawns.
