White is still better, but all of Black's pieces are in play, while White's Bishop and Queen's Rook are still at home.
It is not a good time for White to relax. Imperceptibly, he does.
Suddenly Black is winning! His most blatant threat (besides attacking the Queen) is ...Ng3+, cutting support off for White's Rook.
White can try the counter-attack 20.Nd5, but after 20...Qd4 both of White's Rooks are vulnerable, and after 21.c3 Ng3+ 22.Kg1 Qxd5 White is up material, with better development and more threats.
20.Qg4 Qxf2 21.Nd5 Qd4 White resigned
Black wins the Knight and remains with the better position and continued threats.
