After learning some of the easier lessons myself, I consulted with Red who is not only a founder, but has also written the book on it, for some tips. His basic advise was to use betting as a mechanism to make other players reveal their hands was very useful (ie: never just check or call) and I recenly found myself still with a decent pile of chips as the number of players dropped from 28 to 10.
At this point I figured I should get back to work (and as an employee I wasn't eligible for a prize), so I seriously tried to dump my chips as quickly as possible. However this turned out to be harder than I expected.
Since the other players didn't know what I was trying to do (and probably wouldn't have believed me anyway), they were sometimes intimidated by my moves and would fold their hand (leaving me with more money to get rid of). It was very interesting to see how others reacted to my reckless actions.
In the end, I managed to dump my chips; but by this time there were only four other players left. The interesting thing was that some of the strategies I thought would lose actually turned out to be winners. When one is learning something, answers can turn up in the most interesting places.
