  After `16... Bxa6 17. Qxa6` the problem is that black has **no play**. His white-squared bishop is really important in the upcoming attack on the white king (this is the only play black can try), so if he exchanged it on a6, white would have a very comfortable position (mainly thanks to the attack on the black's weak queenside) and nothing to fear.

  You may oppose me with the fact that white managed to exchange these bishops anyway (see move `18. gxf3` later in the game), but at least black destroyed white's perfect pawn structure.
