best,
Rg6 by one of the Rybkas on ChessOK seems to be slightly positive:
1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. Nc3 e6 5. e3 Nbd7 6. Bd3 dxc4 7. Bxc4 b5 8. Bd3 a6 9. e4 c5 10. e5 cxd4
Weaker was 10...Nd5 11.Nxd5 exd5 12.dxc5 Nxc5 13.Bc2 and White has advantage
11. Nxb5 axb5 12. exf6 gxf6 13. O-O Qb6 14. Qe2 Bb7 Rare move. 14...b4 is typical in this position 15. Bxb5 Bd6 16. Rd1 the only active move is 16...Rg8. 16... Rg8 17. g3 If 17.Rxd4 then 17...Rxg2+! 17... Rg4 Novelty 18. Bf4 Bxf4 19. Nxd4
If 19.Rxd4 then 19...Kf8! 20.Bxd7 Rd8 21.Rad1 Rxd7 22.Rxd7 Bxg3 23.hxg3 Rxg3+ 24.Kh2 Bxf3 25.Qe3 Rg2+ 26.Kh3 Qxe3 27.fxe3 Rxb2 and White is not better
