I am sceptical about Qxe5. Of course black should have avoided a Qeen trade by
any means in this game with 19.Qxd2 or should have played other moves before.
19. Ne4 was a huge strategical blunder.
IMO not a single Master would trade Qeens in such a position.
A typical example of short sighted computer play.
