d5?
Restraining white's centre pawns with moves like Re8, Nc6 & d6 followed by aiming for counter-play based on b4 would keep white's advantage to a minimum.

Do not make unnecessary pawn moves where your opponent is attacking. Re-centralisation by 14..Nc6 or 14..Nc4 was indicated.

With the possibility of meeting Bf7 by e6 clearing e5 as well as g5 for the knights. 20 Rf2 intending N-f1-e3 and Raf1 was an alternative.
20...Kh8?
With a draw offer. As the king is much better on g8 the text simply wastes two tempii. Counter-play with b4 was still correct.
