A remarkable position. Black is totally helpless. After he runs out of pawn
moves he will only be able to move his rook from a8 to d8 on the back rank. In
the meantime the White king will come and take his Q side pawns. It is
interesting that the White position may well be won without any pawns at all!
It is funny that some annotators didn't realise how grave the situation was
and as the material situation is even, they assumed that Black had lost on
time!} 1-0
