One point to make is that with today's engines, since they are essentially just doing search, once you manage to beat an engine once, and you have the game recorded, if you were to replay the game move for move, leaving the engine's settings unchanged, you will beat it again and again forever!

Not true! I have tried this myself and seen the computer play different lines than it did before. On the internet chess club they even have a rule that if you do play the same line over and over again against a computer opponent simply to boost your rating, there are penalties for that.

Yeh I too have tried to be clever and use the exact same line on the same level however it played a different line then before and ended up wining..

Cheaters never prosper PPWPFL!

With some of the laest computer chess programs like Rybka 3 having ratings around 3200, its doubtful any human could compete on that level. However, I don't know how they calculated a rating above 3000 for any program. They don't play grandmasters that often, so how they came up with those sky high ratings I really don't know.
