Analyzing this opening I played I just played what I believe was a set of moves that gave me an overwhelming advantage (I exchanged 2 minor pieces for rook + 2 pawns + prevented castling + doubled pawns + exposed enemy king):

(I am playing Black, so flipping the board is recommended)

[FEN ""]
1. d3  e5 2. e3  Nc6 3. Bd2  d6 4. h3  Nf6 5. Nc3  b6 6. Qf3  Bb7 7. d4  Nxd4 8. Qxb7  Nxc2+ 9. Kd1  Nxa1 10. Qc6+  Nd7 11. Kc1  Be7 12. Kb1  Nb3 13. axb3  O-O


In the final position, one would think black is winning, but in fact engines say I am around -0.50, and I did lose the game. The opponent soon controlled my dark squared bishop after Nf3, and also I couldn't kick the queen away.

What do you think of this position? What color do you think will win more often using non-amateur strength?
In the immediate future Black has major light-square weaknesses and is susceptible to blockade (Nd5, Ba6). It's going to be difficult for Black to break out. Ideally Black would like to get his pawns onto light squares and free his bad bishop but this will be difficult to achieve.

White has an undeveloped kingside, doubled pawns, but easy development and his king is not particularly weak being on a light square. White's ridiculously advanced queen position is surprisingly secure.

I prefer White.
