The entire board position has to be repeated three times *and* every time
the player who moves has to be the same.

I'm not sure if castling-rights or en-passant-possibilities affect the
counting.
For example assume a position where white can castle
0. ...   Bxc3+
(first occurence of position, castling possible)
1. Ke1f2        (now white can not castle anymore)
1. ...   Bc3d4+
2. Kf2e1 Bd4c3+
(second repetition of position, but this time no castling possible)
3. Ke1f2 Bc3d4+
4. Kf2e1 Bd4c3
(third repetition and draw or second repetition if castling affects counting)
3. Ke1f2 Bc3d4+
4. Kf2e1 Bd4c3
(now it is draw for sure)
