I've always had a problem with staying focused in big MTTs. I couldn't even imagine how these guys are doing it at the WSOP. Today, I ran across this quote and a light bulb came on in my head.
“I’ve just been playing table by table,” said Hoyt Corkins, one of the day’s survivors, “and whatever happens I just want to win that table.”
Perfect sense. Take it like an SNG, more or less. Just focus on winning the table you're at. Cool.
