Stop and Go Answered
This is a pretty easy trick. I will tell you that it does not look cool, but it does come in handy. See, stop and go is a trick where the yo-yo literally stops, then starts sleeping again. This comes in handy if you are in a tournament and your yo-yo's sleep is about to die.
First, get into a brain twister mount:
Throw a strong sleeper. Point the index finger of your non-throw hand out and bring the yo-yo up. Now move your throw hand under the yo-yo and up again on the other side.

The trick itself
Okay, now that you are in the brain twister mount, bring your throw hand up and under your non-throw hand so it forms a sort of cup. Now move your hands up a bit and the yo-yo will come up to your hand. Be prepared to catch it. This is the "stop" part of the trick "stop and go".
Now for the "go" part. Bring your throw hand under the yoyo and twist it so your fingers point away from you. Now pull your throw hand down and leave your non-throw hand where it is. The yo-yo should start spinning again and you are ready for more tricks.
