The last post is way off. Cheaters (I have, I am sad to say, done it before) want to play in the same pot. The jist of it is for one guy to have a monster hand, and his partner help him either get more money in the pot and possibly shut out opponents by re-raising (say if there was a draw on the board). Say you raise with AA in EP and get 2 callers. The partner would reraise, keeping the betting/raising alive. It is more difficult than people think; especially in NL games. You have to have some very well thought out signals. And the partner has to be fairly intelligent. Two dumb guys would not do very well cheating - that is why I don't worry too much about it, most players would be incapable of effective team play. Also, you can shoot yourself in the foot. What happens if an opponent flops a set. Then both cheaters lose big. Ultimately, the partner with the rag hand would fold to a bet/raise by the AA hand. That is why you can't catch it. One of them will always muck.

Chip dumping is where in a tourney one guy loses all of his chips to another player. This has marginal benefits, so don't lose any sleep over it. It would be equivalent to one player paying 2x buyin and doubling his/her chip stack.
