In a couple of days I will play a NL Holdem tournemnt at my job. It is a mix of maniacs and people that are pretty good. I have a pretty bad idea about how good different people are. What would be a good approach to play here? A very solid (TAG) game or try to mix up the hands? It's hard to play maniacs. Especially it's hard to keep track of how maniac different people are. Last time the CEO folded his hand on the flop, but since it was kind of half teaching mode, we let him keep the cards since there were no raises (you get the level). Then his opponent went all in on the turn. Then the CEO calls it ... nut flush.

Any hints how to approach the game would be appreciated.
