An unexamined life is not worth living.

The test would have to check both that the problem is correct, and that the problem one and only one solution. Loading a position into Fritz is obviously going to show that, but how would one automatically run a test on the entire database of checkmate problems/studies/tactical solutions?
Has anyone heard of such an initiative and whether this has been ever done either by chess composers or engine authors?
I would imagine those two categories of people are probably quite interested in doing something like this.

If anyone is aware of any new source of a relatively consistent free chess database for offline download in PGN, SCID or Chessbase formats – please post a comment or let me know!

A large opening repertoire
- takes longer to build in the first place
- needs to be memorized and recalled during games
- is more prone to errors in evaluations of critical positions, and as computers get stronger – needs to be periodically reassessed
- may become useless when chess fashion moves to a different direction, and everybody stops playing those “sharp popular lines”
- is more difficult to maintain and update over the years, even if it is digital
While you hope a larger opening repertoire gives you more flexibility, usually the reason your opening files grow large – is because your favourite opening lines give opponent a lot of options, and you have to consider all of them in your preparation. The key to making it manageable - is to limit those options by finding early but solid deviations that you are comfortable with, striking a balance between playing sound lines, and not falling into your opponent’s favourite variations.

I am continuing to play 15 + minute games online in my quest to play 100 “Standard” games online this year, and I prefer games with small increment (15 +2) to avoid being flagged in ridiculously trivial positions, and also to emulate what it’s like to play in real tournaments, which also use increments. I mostly play on ICC, but I am occasionally struggling to find a game with my preferred time controls.
But there is no 15+2 pool or anything similar, which I think is a shame.
I’d be curious to hear if there is a playing site that has such a feature.
UPDATE: as of July 30th, 2015, it seems that ICC heard this request from many other users as well, and added 25 + 10 and 10 + 5 pools, which roughly is what I was looking for! Here is their newsletter.

Here are some that come quickly to my mind:
- Using the engine for analysing your games
- Book flipping
- Chess News reading
- Video watching
- Excessive blitz playing
- Hoarding - books, software, etc
- Caring about rating at the expense of improvement
- Memorizing opening moves without understanding their meaning
- Jumping openings when results don't improve quickly enough
- Finding excuses for losses without looking at root problems
The list is definitely not complete, and there is something that is more true for some chess players than for others.
