Kramnik became world champ in 2000 after beating Garry Kasparov. At 10-years-old, he'd beaten two grand masters.
David also shook the chess world in 1999 when he beat a grand master at his own game.
He's already won the under-eight, nine and 10 British Chess championships and came joint first in the European Under-12s.
Now David plays mostly on the adult circuit, only competing against children his age in major championships.
