A short game (usually no more than 20 to 25 moves), for example: 1.e3 e5 2.Qf3 d5 3.Nc3 e4 4.Qf4?? Bd6! and White resigned in Spiel–Künzel, Europe 1900, because the queen is trapped. However, a significant minority of authors include games up to 30 moves. Usually only decisive games (not draws) are considered miniatures. Ideally, a miniature should not be spoiled by an obvious blunder by the losing side. A miniature may also qualify as a brilliancy. The Opera Game is a famous example. Sometimes called a brevity [chiefly British]. See also Glossary of chess problems#miniature.
