  <li>Nh4 is a blunder since after 14..., Bxe2 to save the bishop (the bishop could also retreat to f7 or e8 to save itself), 15. Qxe2, the pawn fork 15..., g5 will win a piece for Black (this fork could also be made after the bishop retreated, again winning a piece), whereas 14. Nxd4 (discovering an attack on the bishop) will win a pawn for White after 14..., Bxe2 (to save the bishop) 15. Nxe2. The bishop could also retreat in this last line to save itself, but the Black &quot;d&quot; pawn would still be lost to the knight, which could then immediately retreat to save itself. Incidentally, these actions (duscovered attacks, forks, along with several others such as pins) are known as tactics, skill at which is considered one of the most importanct elements for chess success.

  14.Nxd4 takes a pawn on d4, *and* it attacks the bishop on h5. So if black takes back with 14...cxd4, then white has 15.Bxh5, leaving white a pawn up (knights and bishops have roughly the same value). And if black wants to avoid this with 14...Bxe2, white can take back with the knight on d4 (15.Nxe2) so that it is safe too; again, white wins a pawn. And if black retreats the bishop, white retreats the knight, and is again up a pawn.
  
  14.Nh4 does not win a pawn, so that already makes it a bad move when winning a pawn is available. But that is not all: black can first exchange bishops (14...Bxe2, forcing 15.Qxe2) and then *fork* the bishop on f4 and knight on h4 with 15...g5, winning a piece and opening lines against the white king.
  
  That makes 14...Nh4 a blunder.
  
  More importantly, I am not a chess.com user, but can't you press on those magnifier icons to see the line the engine has in mind after each move?

  14. Nh4 is a blunder since after 14..., Bxe2 to save the bishop (the bishop could also retreat to f7 or e8 to save itself), 15. Qxe2, the pawn fork 15..., g5 will win a piece for Black (this fork could also be made after the bishop retreated, again winning a piece), whereas 14. Nxd4 (discovering an attack on the bishop) will win a pawn for White after 14..., Bxe2 (to save the bishop) 15. Nxe2. The bishop could also retreat in this last line to save itself, but the Black "d" pawn would still be lost to the knight, which could then immediately retreat to save itself. Incidentally, these actions (duscovered attacks, forks, along with several others such as pins) are known as tactics, skill at which is considered one of the most importanct elements for chess success. It can be developed by working on tactics problems, which are readily available online.
