That it is impossible to learn fast. But actually modern engine software makes learning and progressing much easier than ever before. training with top engines would mean that you will be able to see some pattern in their approach to the game that would facilitate learning enormously, in sharp distinction to engine software dating back a decade ago, when trying to learn with Fritz would be difficult basically because it would be close to impossible to discern a pattern in its moves, they were like on a random basis. With state-of-the-art engines of today one should be able to progress several times quicker than otherwise, not to mention training with books and a chessboard, where already energetically producing the moves would deprive you of some learning advantages.
Big difference between playing a couple hundred elo about current rating (happens all the time) and playing 400+ elo higher than current rating. Combine that with the fact that most of his moves match Houdini 3's top moves and it's quite obvious he is cheating.
What is annoying to me is that people take the evidence one point at a time and think that is an effective way to refute it.
For example:
1. Anyone can have a good tournament.
2. Everyone matches Houdini's moves sometimes.
3. Anyone can have a bad tournament.
4. Just because he started playing bad when the broadcast went down does't prove anything.
5. It's possible to play 400 ELO over your head or below your rating.
Each issue, taken one at a time seems like a reasonable argument. So people who want to defend the person to the point of unreasonabless just pick one issue and make that the entire justification of the argument. They might talk about each issue in turn but they won't "combine" the evidence in the end, they will image that they refuted this 10 times. Note that in the above example point 1 and 5 are basically the same point, but if you rephrase and repeat you can make it seem like you refuted it twice. It works best when combined with an anecdote about how you once had a great tournament, etc .... SEE, IT CAN HAPPEN so therefore he is not guilty!!!
To show how ridiculous this is, suppose that you are depending on someone to roll 10 dice and report the results truthfully and you will pay them for each 6 they report rolling and that you must pay them the same amount for each 1 that is rolled. It's a silly scenario to trust someone with a private roll, but bear with me. Suppose they report that they threw 10 dice and all 10 came up 6 and you must pay them. Probably, you would suspect them of lying about it because the odds of that happening are 1 in tens of millions. But then someone will argue, "but rolling a 6 is not that rare, I can see me throwing a dice and rolling a 6."
You can really twist this by reasoning illogically and saying, it is expected to roll at least 1 or 2 sixes and perhaps 3 or 4 would not be that far fetched - let's say 4. Not that unusual to roll 4 of them - so that leaves only 6 out of 10. It's not likely but it's certainly POSSIBLE, therefore this is no evidence at ALL!
It's not matching Stockfish, or Komodo, or Rybka, or even Houdini 1.5 or Houdini 2, it's specifically matching Houdini 3. Even that alone is enough to make it obvious that he's cheating and using Houdini 3.
We have shown time and time again that even computers of equal strength have their own styles and will not match the moves of each other consistently. There is still a very strongly held misconception that if you keep getting stronger you are going to match the moves of a strong program a lot more. The reality is that you might match the moves of a strong program SLIGHTLY more and that is it. This misconception give the fallacious argument that "of course he matches Houdini, he is playing really strongly!!!"
It has been pointed out that great care should be taken when chaining together arguments. One could cherry pick what they choose to use as evidence to combine and especially if you are a prosecutor you might sub-consciously be ignoring some evidence that doesn't support you, in the same way that the defenders seem totally blind to most of the evidence. I don't know if it's possible to get a number of "totally independent observations", but you have to use some degree of reasonableness. In my dice example either side could start making up other things to pile on. Perhaps the suspected cheater has a reputation for honesty? Or you can ask, "why would he lie, he already has a lot of money of his own" and you can add that to the defense evidence and try to make that be the one that stands out. You basically just hammer on the ones you want to emphasis and ridicule the rest of the evidence and pretend you are being objective.
Capital punishment would be more effective as a preventive measure if it were administered prior to the crime.
