Hi José,
>> I just had a discussion about draws in the winboard forum... In my mind
>> there is the following theoretical game:
[Event "Test game for Andreas"]
[Site "Virtually in my head"]
[Date "2003.06.17"]
[White "Left part of my head v31"]
[Black "Right part of my head v31"]
[Result "1/2-1/2"]
[TimeControl "endless"]
1. h3 h6 2. Rh2 Rh7 3. Rh1 Rh8 {in fact this is the first repetition, because
of changed castling rights, Quark would think that it is NO repetition}
4. Rh2 Rh7 5. Rh1 Rh8 6. Rh2 Rh7 7. Rh1 Rh8 1/2-1/2 {draw it would take Quark
one repetition more to see that - of course I see no importance in this
example, I have no problems with draws announced a bit to late if they are
anyway correct - but I have problems with draws that are announced to early}

when I am thinking about that game and playing on a board, I think it should be
already claimed as a draw after 5. ... Rh8 ! Because it is the same position
then after 1. ... h7 and 3. ... Rh8... I think that the castle rights do not
play any role here, because afaik the rule goes a bit like this: Three fold
repetition can be declared when a position occurs the third time with the same
side to move and the same possible move - because after 1. ... h7 there is no
draw possible, the possition after 5. ... Rh8 IS the same... What do you think ?
