No. After 27 Qxb6 Rxe5 White has the much stronger 28 Bd5, threatening 29 Bxb7+ Qxb7 30 Rd8+, and Black has no good defence. After 28...Kb8? 29 Bxb7, the best Black can do is the completely hopeless 29...Rb5 30 Qxb5 axb5 31 Bxc8, while 28...Re7 allows 29 Qxa6+ Kb8, when White is two pawns up without even having lost the initiative.

His actual choice, 27 Qa5?! Qg4 28 Re1?!, was unfortunate, as Black replied 28...Qd7, giving White more significant back-rank issues. After 29 Bf4?! Rxe1+ 30 Qxe1 Bxf4 31 gxf4 Qd4 32 Qf1 Nd7 it wasn’t even clear if his advantage should be enough to win, and the game was eventually drawn after tenacious defence by Black.
