Sherlock Holmes: A Game of Shadows question

[Gendo]

Ok, just rewatched this, and there's still something that I don't understand/ didn't catch. What clue did he find that made him think the bomb was at the Opera? And then, when he saw the chess piece (which I understand was a clue that let him know he'd been fooled), what led him to know it was at the hotel across the street? There must have been some clue leading to the hotel that he misinterpreted as leading to the Opera, but what was it?

Also, why'd Moriarty have that guy shot? The one whom he used the bomb to cover it up. The bomb itself would have killed him; it killed everyone else around him. So why bother shooting him first? Just to make sure I guess? But he could have just done the bombing, and then if it didn't happen to work kill him later.

I have seen the film like 3 times and I still don't think I have any answers to your questions.

I had trouble getting into this movie, which was surprising as I enjoyed the first one. I stopped watching after 20 minutes or so and have never tried again.

I had real trouble getting into it at the cinema even though I adored the first film. I got over it by about 45 minutes or so but it's not as good.

I didn't feel it was quite as slick and smart as the first one initially. The second half of the film was up to scratch though.

I like it ok, but not as much as the first.

Someone answer my question! I'd post it in the IMDB forums but jerk-face Vegas got my account killed.
