The game saw ...
28...Rb4?
... after which 29.Ke2 would more-or-less have equalised.
Instead ...
29.Qc3?
... could have been met by 29...Rb5!, after which ...Qg1 could not be stopped (its strength will soon be clear).
Instead ...
29...Rd4+ 30.Ke2
... was soon followed by a draw being agreed.
Correct in the diagram is 28...Qd4+ 29.Ke2 Qg1, which Stockfish16 and Komodo14.1 agree wins. One line runs 30.Kd3 Kg7! (but not 30...Qxh2 31.Kc4 Rc5+ 32.Kb4 Rxc2 33.Qxc2 h5 34.Kxa4, which is equal, according to the engines) 31.g3 Qa1, after which the a2 pawn falls as 32.a3? runs into 32...Rb3+ 33.Ke2 Qh1.
