Why sacrificing a pawn in this situation, 19... h5
is slightly more preferable by engine over more materialistic g6
or Kh8
? This is in fact what Ding chose to play actually. Obviously, this is to protect from 20. Bh6
, but I myself try not to give away pawns when I have reasonable alternatives.
Why protecting dark squares was so important for Blacks even in the presence of the dark-squared bishop?
