Blitz testing
In chess, the idea of a blitz game is that each side is given less time to make their moves than under the normal tournament time controls. It's also often used to help a chess player who's learning chess develop their intuition. When playing a blitz game, you don't have time to think 30 moves out (or for us mere mortals, 5 moves). The idea, when used as a learning tool, is to compare your first impression of positions with the way they are actually developed during the game.
I think this can also be a good learning tool for testers. For me, a normal test session is around 45 minutes. One way for me to practice is to give myself 5, 10, or 15 minutes instead of my traditional 45. I'll want to achieve the same level of coverage in that small amount of time, so I'll need to move incredibly quickly to do so. At the end of that blitz session, you go back and execute the full session (or the rest of the full session). When you're done, you can go back and analyze what you missed in your blitz session and try to understand why. You can also look at things that you found that you think you might not have found if you were being more slow and deliberate. (However, that analysis is more difficult to do.)
The goal here is to try to understand both how your testing changes given the amount of time you have (which is valuable to understand), but also to help you develop your intuition for where risk is within the product and which techniques are going to be most helpful and under what conditions.
