I just played a 3 0 blitz game, and got a position where we repeated the same position FIVE times. This means there were 3 times I could have claimed a draw.
On the third, fourth and fifth repetition, I clicked "claim draw" immediately. Each time, it took a couple seconds to go through, and before the draw was officially claimed, my opponent made a nother move, canceling the draw claim. This seems like a pretty big problem, since as long as you spend less than 2-3 seconds per move, it is impossible for your opponent to claim a draw. Maybe this could be changed so that as long as one player claims the draw, even if the opponent makes another move, the draw still stands, since this seems like an issue on the site, not with my connection (I have about 150ms ping).
