People just need to apply common sense, that"s all. Its difficult to give guidelines to cover all situations, because as well as team mates, there will also be up to 7 other people at the table, some of which may be good enough to exploit a team-mate situation to their advantage.
From my point of view, i will not be "getting out of line" against a team-mate like i may against any other opponent - and i think this should be borne in mind by all team-mates. Therefore just do what you can to avoid team-mates at early stages but i won"t be going to extremes such as folding aces on the bubble or anything like that (although to use Wayne"s example i may fold AQ).
Situation gets a bit more complex when we close in on the points bubble, i will probably fold some hands that i would normally call against anyone else but won"t be folding aces, kings queens etc.
Therefore i dont tend to play these expecting favours from my team mates, just not to do anything unreasonable against me - does that make sense?
