I think that it can't. The third repetition of the position is
a virtual position, which occurs on the protocol. Assuming
that White's last move was 45.Bf4 repeating the position for
third time it is illegal. He should write that move on the protocol
and claim for draw, but not make the move on the board. My calcu-
lations end to 42.5 moves. It is at least fourth different answer.
Someone could show the actual moves rather than trying to get the
answer by addition and multiplication. Olli.
