Finding this thread in the net is great.
After a pause of 20 years of tournament chess I decided to restart with correspondence chess and a completely new repertoire. The book of Vigus is my black bible against d4 atm.

I never played the slav before and it gave me a really good start.
So maybe it's possible to give back some experiences. Relying on the English edition from 2008 there are my first remarks.
- Chapter one - page 58:
1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. Nc3 dxc4 5. a4 Bf5 6. Ne5 Nbd7 7. Nxc4 Nb6 8. Ne5 a5 9. f3 Nfd7 10. Nxd7 Nxd7 11. e4 Bg6 12. Be3 Qb6
13. Qc2 This seems to be a new move here, played by E. Ortiz from Cuba. The book doesn't cover it and I couldn't find a game neither in CA10, nor in several other bases. Atm I'm analyzing 13. - e5 or 13. - e6.
- Chapter nine - page 187:
1. d4 d5 2. c4 c6 3. Nc3 dxc4 4. e4 b5 5. a4 b4 6. Na2 Nf6 7. e5 Nd5 8. Bxc4 e6 9. Nf3 a5 10. Bg5 Qb6 11. Nc1 Ba6 12. Bxa6 Qxa6
Here is the text: 12. ... Qxa6 exploits the fact, that White hasn't castled. (13. Qe2 c5 14. dxc5 Nd7)
But M. Santo from Andorra gives me a hard time atm with his plan of blocking c5.
13. Nb3 Nd7 14. Rc1 h6 15. Be3 Nxe3 16. fxe3 Be7 17. Qe2 O-O 18. Qxa6 Rxa6 19. Ke2 Rc8 20. Rc2 * so far the game has run.
As I'm an otb player beyond the level of 2000 pardon me, if this is bs.
