This endgame features a quite surprising defensive resource by Black to save what should have been a lost endgame.
The 7-man ending began after Black's 46th move. Initially White was winning.
Black chose an objectively inferior line of defence that offered practical chances and this paid off.
At the critical moment GM Nisipeanu failed to see the necessity to give up his rearguard pawn.
The second diagram shows the position at that point. Young Indian grandmaster Adhiban seized his opportunity.
With a succession of threats to force repetition, win the advanced g-pawn or even to deliver checkmate (from two different directions!) he forced his opponent to underpromote to a knight.
Adhiban then held the resulting knight-down ending quite comfortably.
