Suspect line in Cambridge-Springs

Hi guys! Was reading Panczyk & Ilczuk (hope got the names right!) and saw a suspect variation (although played by the likes of Reti, RUbinstein, Teichman, Ljubojevic, Smagin et al,):

1. d4 d5 2. c4 c6 3. Nc3 Nf6 4. Nf3 e6 5. Bg5 Nbd7 6. e3 Qa5 7. cxd5 Ne4 ?!?!

The authors say that although white needs accurate play the line is inadiquate for black, giving the following variation as one of the possible refutations:

1. d4 d5 2. c4 c6 3. Nc3 Nf6 4. Nf3 e6 5. Bg5 Nbd7 6. e3 Qa5 7. cxd5 Ne4 8. dxe6 fxe6 9. Qa4 Qxa4 10. Nxa4 Bb4+ 11. Ke2 b5 12. a3 Nxg5 13. Nxg5 Be7 14. Nxe6 bxa4 15. Nc7+ at this point Rybka suggests 15...Kf7 16. Nxa8 Bb7 17. Nc7 Bd6 18. Rc1 Bxc7 19. f3 Ke7 20. Kf2 Bb6 21. Bc4 which the authors of the book analize up to here giving +/-. However the fish goes c5 22. Rhe1 Rb8 and says the position is =.

What do you guys think?!
In my view white's pawn center may be scary in the future, but at the moment it is... scared by the black pieces and I do not see how it can be preserved.

The other assumed refutation is based on the game Cvitan-Ljubojevic:

[Event "YUG-ch"]
[Site "Vrbas"]
[Date "1982.??.??"]
[Round "?"]
[White "Cvitan, Ognjen"]
[Black "Ljubojevic, Ljubomir"]
[Result "1/2-1/2"]
[ECO "D52"]
[WhiteElo "2430"]
[BlackElo "2600"]
[PlyCount "38"]
[EventDate "1982.??.??"]
[EventType "tourn"]
[EventRounds "17"]
[EventCountry "YUG"]
[EventCategory "9"]
[Source "ChessBase"]
[SourceDate "1999.07.01"]

1. Nf3 Nf6 2. c4 c6 3. Nc3 d5 4. d4 e6 5. Bg5 Nbd7 6. e3 Qa5 7. cxd5 Ne4 8.dxe6 fxe6 9. Bh4 Bb4 10. Nd2 Nxc3 11. bxc3 Bxc3 12. Rc1 Nf6 13. Bd3 e5 14. dxe5 Bxe5 15. O-O Bg4 16. f3 Be6 17. Nc4 Qc5 18. Nxe5 Qxe5 19. Qe2 O-O 1/2-1/2
where 16.Qc2! would have been difficult to handle for black.

Here however Rybka suggests as an improvement: 13...0-0 and onkly after 14.Rc2 (in order to castle) 14...e5 with a slight advantage to white.
Best should be 14.Qc2 Bb4 15.Rd1 Qh5 16.Bxf6 gxf6 white is slightly better, although it doesn't seem so dramatic to me or Rybka.

In my view this may be the critical line.
