What's a miniature?

Just asking.

A short non-drawn chess game. There is no official standard for length, but anything under 20 moves is a miniature in my book.

A game played on a small set. It has to be very small to qualify as miniature. 

I think it has to be 20 moves or less.  It is stretching to call a 20 move game a miniature.

Here is a somewhat relevant question--What is the average length of a chess game?  [you could ask by class  class D to super grand master] A miniature would have to be considerably less moves than average.

I heard it was 31.

I thought it was 26.

I consider a miniature usually below 20.

The average is probably pretty low but miniatures don't include draws so average length of games that aren't drawn should be taken instead.

Most chess games one side or the other has enough to win by the 15th move so a game of  more than 20 moves should not be called a miniature.

Like most chess enthusiasts, I was taught a couple of centuries ago that a 'miniature' was a game that consisted of 20 moves or less - but I think it's time that we consider changing that! If a casual player like me was able to memorize almost every popular chess opening variation for the first dozen moves or so in my free time, then I guarantee you that every GM on the planet has memorized a LOT more than that! Any game played by 2 top GMs today that ends in less than 20 moves will almost ALWAYS result in a draw nowadays (and always by repetition of course). Can you say the Berlin? Ugh!
