9...Qe7?
Black clearly hoped to regain the pawn without making any concessions, but he's in for a surprise. [9...Be6
is both obvious and good, as long as Black meets 10.Qd3
with the less obvious 10...Nb4!

Suddenly, the game is as good as over. Black's king is stuck in the center, and exf6 and especially exd6 are crushing threats.

The only sensible move.
12.Rhe1!
Black has no answer to the threat of Nxe5, and so Nakamura already decided to call it a day. Even great players can slip on the proverbial banana peel! [12.Rhe1!
