Actually, it is pretty simple. When you have an all in table going, you can win a lot of chips in a hurry. This last week, I sat several tables in which players were throwing 1m all in, preflop... I was winning 2-3 million pots for hours on several players. I even tried to get them to slow down in the table chat.
Alexander mentions having an obsession for the cups... I have made 4 of them since I started. I could care less about them.
With all the hours I play this game, this was a rare week. SO it's nothing special... I had a few days of really good cards, on a few tables that were playing out of control. Yep, I took advantage of it.
Hope that helps
