I've not played blaickner but in my opinion I would not accuse someone of cheating unless you have solid proof. Some people are just that great at a game. And i'm sure if you gave those people the chance they could help to improve your game as well.
And Gary, yes people do use cheating materials for the games at Pogo. I knew someone who was a pro card player and she played one of the games there (i don't remember which one) they said they had only played once or twice and totally beat her and not by luck...i mean the game went on for like an hour or so. She said she had pro tactics but got beat anyways.
