This time I'm going to talk about games with 1-5 minute timers. I hope you'll find this helpful!
Keep an eye on the clock at all times
This is a simple rule that can be the difference between winning and losing. Try to keep your timer higher then your opponents. If you don't then you can have yourself trying to make up for that time with bad moves.

13. a3, Nc6 14. Nd5, Nxd5 15. Bxd5, Qxb2 16. Bxc6, bxc6
So, time can play a huge factor. A good thing to do is to:
Use opening traps
A personal favorite of mine is this:
1. e4, e5 2. Nf3, Nc6 3. Bc4, Nf6 4. Ng5, h6? 5. Nxf7
This is a simple rule because of time. Their time can run out and you can still win.
