From the diagram after Black's 38th move, Dragan recommends 39.Qh4!, instead of the game continuation 39.a3?? Qb3 40.Qc2 Rxc3! winning for Black . Play might continue 39...Bxc3 40.Qxb4 Bxb4 41.Rxd5 Rh8 42.h4 Be1 43.Rg5 with good drawing chances.
A likely continuation would be 43...Kb7 44.h5 Bxg3 45.Rxg3 Rxh5 with a book draw.
