Body: <p>I would like to receive some feedback on my mistakes of the <a href="https://lichess.org/B7FLCZBd/black#13%E2%80%98" rel="nofollow noreferrer">below Lichess game</a>, if possible from someone above 2000.  I an unsure about the reason of the mistakes I did in the game. When I finished the game I thought I had won quite convincingly, but apparently, I made some mistakes early in the game.

  <p>I played 7... e4. Later, I realized that d4 was probably better but I get the feeling that after 7... d4 8. Ne4 Be7, Black has lost some initiative. </p>

  <p>I played 8.. h6 as White’s Bishop is forced to be exchanged on f6 or to retreat to a passive position. I calculated 9. Bxf6 Qxf6 10. Nxc6 bxc6 with a more or less favorable position in which the powerful center, which will be stronger after c5, is an advantage for Black. However, Stockfish evaluation drops around 1.</p>

  <p>I played Bb4 threatening to win a pawn. However, it is considered a blunder. I do not understand this. I do see that 12.Qd4 forces the Queen trades, but to me, the position is not much worse for Black for it.</p>

  <p>Given that the g3 pawn of my opponent is on a dark square, I thought of trading the bishop. I now realize that maybe this bishop had some prospects on the g1-a7 diagonal, but again I am not sure why this qualifies as a grave mistake.</p>
  
  <p>Note: If possible, could you please also tell what move number you would stop at in order to calculate variations? I am unsure if I am doing this at all, but all my calculations take only 6 moves at best by each side. I know that in the middlegame, I should probably do some analysis of variants but in games I am not sure how deep these analysis should be.</p>
