question for you guys.. this is a game from another site.. I put a ticket in to the admin saying this game is threefold repetition, because the board was in the same position three times, but their admin said no because it wasn't the same colour that did all three moves into that position.. Here is the game.. moves 44, 46, and 49 have the board in the same position. Am I incorrect? that it has to be the same person to move last to make the board in the same position each time?

sorry. .other site doesn't give FEN's that I can find., and I don't know how to create them.
One other thing about the 3 fold rule, FYI...
I have also read that not only must it be the same player's turn to move each time, but castling privileges must be the same all three times as well...
For example, take a position which occurs twice, and a King (doesn't matter which King) is eligible to castle... if that King subsequently moves, and then moves back to it's original square (i.e. it is now ineligible to castle), and then the same position occurs a third time, it is not considered a draw by repitition, because castling privleges are different the third time the position occurred. (First two times, King is eligible to castle, third time, King is not eligible to castle).
Sometime, even the greatest players misuse this rule... In (I think) the 20th game of the Fischer-Spassky WC match in 1972, Fischer incorrectly claimed a draw by 3 fold repitition...but although the position had occurred three times it had not been repeated with the same player to move each time...(However, the draw stood, as Spassky did not dispute the claim).
and... to add one more, but almost never seen possibility that the admin told me after.. was even the same en passent capabilities.
so., if on the first repetition, the next move someone can use en passant but they don't.. the next two repetitions, even though the board is the same, its not exact, because the player can no longer use en passant.
