Comments.Text: Maybe you could switch up the move order, and play c4 first. That way Bd6 is impossible, due to c5. And one more note: it's never very interesting to know the "the best move for you". A move is either good, ok or bad, and that NEVER depends on the player. It ONLY depends on the current position on the board.

Comments.Text: If Rc1 then Ba3 (noted by **CognisMantis**) actually traps the Rook (Ra1 Bb2).  Since you're going to lose the Exchange, you might as well continue with c4, but it seems a rather speculative sacrifice.

  Stockfish thinks `1. Rc1` leads to a even game or maybe a draw. It's undone immediately by `1. ... Ba3`.
  
  Stockfish preferred `1. Nh4` with a 60 centi-pawn advantage to White.
  
  ```
  [FEN "2kr1b1r/pp3p1p/1q2pp2/3p1b2/3P1B2/1PP2N2/P4PPP/R2QR1K1 w - - 0 1"]
  
  1.Nh4 Bg6 2.Qf3 Be4 3.Qh5 Rd7 4.Rad1 Rg8 5.c4 Bb4 6.Re3 Qc6 7.Qe2 Bd6 8.Bxd6 Qxd6 9.f3 Bg6 10.c5 Qf4 11.Nxg6 hxg6 12.b4 Qc7 13.b5 Kb8 14.Rb3 b6 15.Qe3 g5 16.Rc1 Qf4
  
  ```
  
  The `1. c4` move fares ok at about 40 centi-pawns but by the end any winning chances look like an illusion.
