I have accidentally deleted my previous post about threefold repetition.
In summary, I asked why in the game I was not given the option to claim draw by repetition since I had the positions:
20. Bxh7+ Kxh7 (first time)
21. Qxd4 Kg8
22. Rbe1 Kh7 (second time)
23. Re4 Kg8
24. Rfe1 Kh7 (third time, draw?)
Someone answered saying that this is because my opponent was moving different pieces, which makes sense, but then I don't understand how Bobby Fischer claimed draw by repetition as described by wikipedia here: http://en.wikipedia.org/wiki/Threefold_repetition
He was playing white. It says he had the positions:
30. Qe2 Qe5
31. Qh5 Qf6
32. Qe2 (second time) Re5
33. Qd3 Rd5?
and then Fischer wrote his next move
34. Qe2 (third time)
on his scoresheet, which is the third appearance of the position with Black to move, and he claimed a draw.
In this case the opponent was moving different pieces too! So how could he claim and I could not? I don't understand the difference between these two scenarios. Looks like a bug in the web site to me, but I'm probably missing something...
Any help is appreciated!
Thanks!

The snapshot of the pieces on the board is not the same , just the position of your pieces only.

The rule applies to positions, not moves. Whybish is right. Snapshot#20 can't be a replica of snapshot#22 because there is a capture Qxd4 on the 21st moves.
