All Stars competition

I already in Round 1 leading the board with around 200K points ahead of my opponent. I got a lead when I noticed she suddenly stop playing around midnight. So I got lead. Now I noticed she resume playing and I am very surprised that she got back to lead that so fast within only atleast 2 hours. I wonder how it is. I know playing takes times too mostly if moves is less. I able to spend a lot too for buying boosters. Crazy but fun. But this one is just makes me wonder. I get to have a lead for the whole night playing without sleeping too, but she only took it hours. Can you able to check if there is no cheating involve? I just can't get over this. Thanks
