This is a tricky call. Who defines 'understanding' a game?

This is a subjective measure. I can think of two examples to illustrate this:

a) on Tim Krabbe's pages he sometimes has the topic 'computers can't play chess'
and demonstrates positions where the computer does really awful things (in his
eyes)
So 'computers can't play chess'.

On the other hand in his analysis he sometimes refers to a move found by the
computer. Often this is a good move the human would have a lot of trouble
finding. 'Humans can't play chess?'

b) my own program plays several variants which it has very little understanding
of. In one variant is just picks the move that offers it the most options not
to get mated. In another the only heuristic it has is 'put pieces near the
opponents king'. In a way it does not understand the game at all, by human
standards. Yet it is at the same level of top human players. It makes awfull
moves by human standards. Yet it often wins with those moves.

I think this holds a lot of truth.

This assumes you can express GM in term of an ELO rating. I do not think
that is possible, or at least has any meaning.
