Greatest gap between player skill levels

[Juslas]

During my placement matches, I had not read forum nor learnt about rushes or first player advantage. My placement matches ended 3 won 2 lost. Last three of the games are shown on this screen capture:

Later I read Outwitters news and thought wait a minute, I played against Kasparov (of the Outwitters.) That makes one mighty skill level difference since I ended up starting as fluffy league and my opponent was number one best player of all those Super Titan skill level players.

There was nothing to see on my quick lost, sure I learnt that defending is essential when playing second ... and I also later learnt how to save game replays. This game was already lost then.

Does anybody else recall great skill level differences between players.
Though this one is hard to beat. Number one against not yet ranked player.
