That didn't seem so bad. You can see with how much he was toppling pieces that he was having trouble with nerves, which would make the situation all the more frustrating. When players have an increment to play with rules should be decisive on "loss on time is a loss, doesn't matter the position". But here we have some edgecase which settles on some crazy sequence for black to ever win (if white didn't have pawns, the game would've been declared a draw)

Basically have some empathy, losing is rough & in a tournament most players are losing, for all we know he just needed to sleep on it & came around the next day
