You've right here 6.Qd4 ed5 6.e4 is the critical var.

The Pillsbury-Lasker games I'm aware of were with 5. Bg5 (rather than 5. cd) cd 6. Qxd4.

In the famous Zurich 1953 tournament, covered in the equally famous book by Bronstein, Keres introduced the line 1.d4 d5 2.c4 e6 3.Nf3 Nf6 4.Nc3 c5 5.cd5: cd4:!?. He played it a couple of times in the tournament and got excellent results (not a single loss). Do you guys know what the current theoretical verdict is on this line is? 

It's call Pillbury'variaton (D50) There 're some famous games Between Pillsury and Lasker long time ago
If white play 6Qd4 it's old Pillbury And 6.Nd4 is modern Pillbury  and 6.Qa4+ is D41 Eco.
It's compltely playable
But without Nf3 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 c5 is now dubious 5.cd ed 6.e4! It's call the Dutch-Peruvian (D50)

My understanding is that while it's an interesting attempt to side-step theory in an occasional OTB game, White should get an advantage with very precise play.

Having said that, I've never seen any correspondence games in this line.

I like 6.Qa4, but 6.Qd4 transposes to a line of the Symmetrical English that's supposed to be about equal.

This line has some transpositional possibilities with the Von Hennig-Schara Gambit. The theory on that line is that White has a nice advantage, but Stefan Buecker has written more on that on another thread.

It's an entertaining line that I as a first player would challenge with: 1. d4 d5 2. c4 e6 3. Nf3 Nf6 4. Nc3 c5 5. cxd5 cxd4 6. Qa4!? Bd7 7. Qxd4 exd5 (7... Nxd5?! 8. Nxd5 exd5 9. Qxd5 Nc6 10. Bd2!?) 8. Bg5 Nc6 9. Qf4!?..
I think this approach is better for white than the lines beginning with 6. Qxd4 although I admit this is more of a personal taste than an overall assessment.  Cool
