Beware of the Re-Buy tournment
When you play in a re-buy tournment it is much harder to bluff and push people off of their hands. Unless you are willing to do a lot of re-buying yourself, play tighter as people will tend to chase hands since they know they can always buy more chips. This is especially true at a charity event where people have a few drinks and chalk it up to the money going to a good cause. I found that out in a recent charity event with a very high buy-in. If people seem to be very loose with their money stick to playing quality hands.
