I find the GM cheating fascinating. I mostly agree with Water Bob: I would call the actions of the GM inappropriate, not cheating. Suppose a chess noob asks his friend who is good at chess to teach him how to play chess. The noob knows his friend can clean his clock anytime he wants to and he tels the teacher not to hold anything back. If he subsequently goes easy on the noob, he would accuse the teacher of going easy on him. But the noob shouldn't call him a cheater.
So, I have a question for the folks who say the GM CAN cheat: Suppose there's a game group where the GM/player contract is the GM will not fudge rolls to go easy on the group: all rolls in the open, etc. The players want a world where if they screw up, they die.
The party has been beat up a lot in a prior encounter and they open the next door and find out 6 skeletons rise up to attack. The adventure says there are 8 skeletons in the room, but he's dropped it to 6 to avoid a possible TPK. Did he cheat? Does your answer change if the module is his own home brew versus a real printed adventure?
Suppose the GM is just whinging it and he decides there are 6 skeletons in the next room on the spur of the moment. But based on the EL of the rest of the dungeon a proper encounter would have 8 skeletons. Did he cheat?
So when does it become cheating? Where's the line? The encounter was designed for 8 skeletons and the GM only puts out 6 minis/only describes there being 6 skeleton. You each seem to say that is not cheating. Do the skeletons have to be "on stage" for there to be cheating?Changing a written module to fit your game better is not cheating the same if you change your encounter on the fly to take out an extra mook because the party is not in the shape to handle it or adding one because the party is stronger then you think.
The GM in all my examples is pull his punches when he said he would not and thus he acted inappropriately. But he did not cheat.

So how about if he describes the encounter and says there are 8 skeletons but two of the skeletons just never attack for various contrived reasons. Is that cheating?
How about this? The party is getting rocked by some unknown new monsters when the party wizard casts sleep in desperation. The GM knows they are 2HD monsters but he treats them as 1HD causing four of them to make saving throws because he didn't expect the encounter to be so brutal. If the players find out later they are normally 2HD can they say he cheated?
The point is cheating is generally a break in some social norm. But not all breaks in social norms is called cheating. The GM in all my examples is pull his punches when he said he would not and thus he acted inappropriately. But he did not cheat.

The implied contract at our table is that the DM is not to be argued with in how he chooses to run the game. If the DM is poor, then his game dies and someone else runs a game. However, even the fudgiest DM knows that to openly fudge robs the players of tension and accomplishment. The only good fudge is the one the player is never aware of, and only enhances their enjoyment of the game.
Now I am not sure most players who want the DM not to fudge or pull punches would have the same issue if the DM is adjusting things on the fly because he made a mistake and the encounter is not one where the party never stood a chance.
